6 PREFACE Standards for Defence Identification marking of Transportable Containers, Compressed Gas a. This standard provides requirements for the identification marking of MOD owned and hired Transportable Containers, Compressed Gas. It does not apply to containers used in portable fire extinguishers, certain HPPA containers and US DOT standard containers. b. This standard has been produced on behalf of the Defence Materiel Standardization Committee (DMSC) by the Standard Advisory Group E/6. c. This standard has been agreed by the authorities concerned with its use and is intended to be used whenever relevant in all future designs, contracts, orders etc. and whenever practicable by amendment to those already in existence. If any difficulty arises which prevents application of the Defence Standard, the Directorate of Standardization (DStan) shall be informed so that a remedy may be sought. d. Any enquiries regarding this standard in relation to an invitation to tender or a contract in which it is incorporated are to be addressed to the responsible technical or supervising authority named in the invitation to tender or contract. e. Compliance with this Defence Standard shall not in itself relieve any person from any legal obligations imposed upon them. f. This standard has been devised solely for the use of the Ministry of Defence (MOD) and its contractors in the execution of contracts for the MOD. To the extent permitted by law, the MOD hereby excludes all liability whatsoever and howsoever arising (including, but without limitation, liability resulting from negligence) for any loss or damage however caused when the standard is used for any other purpose. 4

7 TEXT Standards for Defence Identification marking of Transportable Containers, Compressed Gas SECTION 1 GENERAL REQUIREMENTS 0 INTRODUCTION This standard is concerned with the identification marking and colour coding of transportable gas containers owned and hired by the MOD and medical gas containers hired by the MOD. It gives details of the stamp marking, labelling, stencilling and the colours to be applied to the containers to identify various gases and gas mixtures. This Defence Standard has been updated to reflect the continuing trend for the MOD to lease gas containers instead of owning them; and, changes in European and International requirements for gas container identification marking. In particular: the withdrawal of parts or all of the BS 5045 and BS 5430 series of gas container standards and their replacement by new European standards; new European and ISO standards for marking and colour coding of gas containers; and the requirements of the Restructured ADR and the UN Model Regulations on the Transport of Dangerous Goods. To reflect these changes, this standard provides dual requirements: markings for existing MOD containers, obtained prior to 1 st July 2003, that need to be maintained in service use, albeit with some changes when next serviced; and the markings for new containers that comply with the EN and ISO standards. Any queries or any discrepancies found between this document and legislation or Industry Standard Codes of Practice shall be referred to the Engineering Authority concerned. 1 SCOPE This standard aims to: facilitate the purchase of new transportable gas containers; assist in the maintenance and refurbishment of the MOD s existing stock of transportable gas containers; act as the UK implementing document for a number of NATO Cross-Servicing agreements; and to help ensure the MOD s transportable gas containers comply with the requirements of UK, European and International legislation. It specifies requirements for the identification marking and colour coding of transportable gas containers owned and hired by the MOD for the storage, transport and use applications of compressed permanent, liquefiable and dissolved gases. It is divided into separate sections covering General Requirements for all applications, Ground containers, Airborne containers, Diving containers and Medical containers. This division reflects the different operational requirements that each type of container may be exposed to. It does not apply to containers used in portable fire extinguishers, as these are covered by European Standards. It does not apply to special to type 0.33 litre, 0.60 litre and 2.40 litre HPPA containers as these are covered by Def Stan

8 SECTION 1 GENERAL REQUIREMENTS It does not apply to US DOT standard containers. The identification marking of self-filled personal use containers which may contain various mixtures of breathing gases is not included in this standard but should be in accordance with its general principles as far as possible. 2 WARNING The Ministry of Defence (MOD), like its contractors, is subject to both United Kingdom and European laws regarding Health and Safety at Work, without exemption. All Defence Standards either directly or indirectly invoke the use of processes and procedures that could be injurious to health if adequate precautions are not taken. Defence Standards or their use in no way absolves users from complying with statutory and legal requirements relating to Health and Safety at Work. 3 RELATED DOCUMENTS 3.1 The publications shown below are referred to in the text of this standard.

11 SECTION 1 GENERAL REQUIREMENTS 4.1 Certification Marks A group of Stamp Markings, defined in the Restructured ADR and UN Model Regulations: covering the UN mark, the container s technical standard, symbols identifying the Country of Approval, the Inspection Stamp and the Date of Inspection. (See Annex A and BS ISO 13769). 4.2 Colour coding Defined as, a system of colour coding Containers as a means of identifying their contents by reference to the property of the gas or gas mixture. For compliance with BS EN , colour coding only refers to the identification colour, or colours, on the shoulder of the container. 4.3 Container Defined as, a generic term covering bottles, cylinders, etc., which are used as vessels to contain and store compressed gases. 4.4 Manufacturing Marks A group of Stamp Markings, defined in the Restructured ADR and UN Model Regulations, including the container thread Identification, the manufacturer's mark (preceded by the country of manufacture code when this is different), the serial number, the letter "H" when applicable. (See Annex A and BS ISO 13769). 4.5 Nitrogen padded The addition of a secondary gas charge (nitrogen), as a discharging agent, to a gas container holding a main charge of liquefied gas in order to minimise any changes in the outlet supply pressure of the main gas caused by changes, particularly reductions, in external temperature. 4.6 Operational Marks A group of Stamp Markings, defined in the Restructured ADR and UN Model Regulations, including: test pressure, empty mass of the pressure receptacle, minimum guaranteed wall thickness of the pressure receptacle, the water capacity (for liquefied gases). (See Annex A, BS ISO and EIGA Position Paper 03/2002). 4.7 Other Marks The term used in BS ISO 13769, the Restructured ADR and the UN Model Regulations to refer both to Stamp Marks required by regulations, such as the Inspection Body stamp and the date of the last inspection stamp(s), as well as stamp marks required by the owner, such as the MOD pheon mark and the NATO stock number. (See Annex A and BS ISO 13769). 9

12 SECTION 1 GENERAL REQUIREMENTS 4.8 Pi (P) Mark A Stamp Mark, required under TPED, certifying that the container is compliant with the Restructured ADR. Note: the style of the Pi mark is defined in TPED, the above Π mark does not conform to the required style (see Figure A.1). 4.9 Precautionary Labelling Defined as, a generic term covering the means of identifying the contents of each container; warning of principle hazards by means of a coloured hazard diamond(s) and words; and for providing other information such as the chemical name and formula of the gas or gas mixture. Specific examples of how this might be achieved include self-adhesive labels, stencil marks, or transfers, and various combinations of these Proper Shipping Name A means of naming Dangerous Goods. Each Proper Shipping Name is directly linked to its UN Number. (See Annex B, the Restructured ADR and the UN Model Regulations.) 4.11 Stamp marking Defined as Permanent Markings applied to the container, usually by hard stamping on a reinforced part of the container, which provide Manufacturing, Certification and Operational information. However, in the case of light-weight composite-wrapped containers, such permanent markings have been achieved by labels contained under the transparent outer layer of the resin matrix. Non-ferrous stamping rings soldered onto the neck provide an area for Stamp Marking on some Airborne containers UN Class Number A set of Classes and Divisions allocated by the UN to identify classes of Dangerous Goods based on their hazards. Gases fall into Class 2, Gases, and are further divided into three Divisions: i.e. Division 2.1 Flammable gases; Division 2.2 Non flammable, Non toxic gases, and Division 2.3 Toxic gases (see Annex B, the Restructured ADR and the UN Model Regulations) UN Mark Defined as a UN Packaging symbol, of specified design, denoting that the container complies with the Restructured ADR requirements for UN certified pressure receptacles. 10

13 SECTION 1 GENERAL REQUIREMENTS 4.14 UN Number A number allocated by the UN to identify Dangerous Goods. It is directly linked to the Proper Shipping Name (See Annex B, the Restructured ADR and the UN Model Regulations). The number is preceded by the symbol UN UW Mark Defined in the Restructured ADR and UN Model Regulations as a Stamp Mark signifying that a composite cylinder intended for underwater use is compliant with the Model Regulations. 5 ABBREVIATIONS Designation Title ABCA American, British, Canadian and Australian Armies Standardization Programme ABO Aviator s Breathing Oxygen ADR European Agreement concerning the International Carriage of Dangerous Goods by Road BS British Standard BS EN European standard having the status of a British Standard BS ISO ISO Standard implemented as a British Standard Def Stan Defence Standard DOT U.S. Department of Transportation EIGA European Industrial Gases Association HPPA High Pressure Pure Air ISO International Organization for Standardization NATO North Atlantic Treaty Organisation NDT Non-destructive tests QSTAG ABCA Quadripartite Standardization Agreement STANAG NATO Standardization Agreement TPED Transportable Pressure Equipment Directive UN United Nations. 6 GENERAL INFORMATION 6.1 General The MOD has traditionally used Stencilling as a means of labelling the contents of containers and of providing a warning of the associated hazards. However, relying on stencilling alone may not provide all the precautionary information required under the Restructured ADR. 11

14 SECTION 1 GENERAL REQUIREMENTS The appropriate Engineering Authorities for Airborne and Ground Containers have agreed that alternative methods of marking may be used in place of, or in conjunction with, stencilling to provide the required precautionary information, e.g. transfers and adhesive labels. Where alternative methods of labelling and stencilling are proposed for identification marking of other categories of Containers, e.g. Medical Containers and Diving Containers, these changes shall not be implemented unless the appropriate Engineering Authorities agree. For further information reference may be made to the Engineering Authority responsible for that particular section of the Defence Standard (see Annex C). 6.2 Stamp marking Stamped markings shall not be less than 2.5 mm in height for containers less than 140 mm diameter and should where possible be a minimum of 5 mm in height for containers equal to or greater than 140 mm diameter. Where a UN Mark is used, it shall not be less than 5 mm in height for containers less than 140 mm diameter and a minimum of 10 mm in height for containers equal to or greater than 140 mm diameter. 6.3 Character marking Characters used in stencils, labels or transfers should conform to the sizes given in Annex D where practicable. 6.4 Symbol marking Where alpha-numeric symbols are required to be stencilled or stamped on the container or collar, these symbols are to be presented in block capitals in order to conform to accepted trade practice. Note: In Europe decimal places are denoted with a comma, e.g. 25,5, in contrast to the normal UK practice of a decimal point, e.g Similarly, in Europe a space is used to mark thousands, e.g , in contrast to the normal UK practice of using a comma, e.g. 10,000,000. The European convention shall be used for container marking. 6.5 Notes to tables The Notes applicable to the tables in SECTIONS 2, 3, 4 and 5 have been collected together and are listed in SECTION 6. 12

15 SECTION 1 GENERAL REQUIREMENTS 7 HAZARD WARNINGS 7.1 The Filler of the container shall ensure that the container is correctly labelled and that safety and other statutory markings and labels on containers conform to the European Transportable Pressure Equipment Regulations, and International regulations, e.g. Restructured ADR or UN Model Regulations, appropriate to the product and the movement involved. (See Annex B). 7.2 Where transit cases are used to transport gas containers, it shall be responsibility of the packer to ensure that both the transit case and the gas container shall be fully labelled so as to identify the contents of the gas container, its properties and the associated hazards. (See Annex B). 7.3 The primary method of identification of a gas container is by the name of the gas marked on the container and its warning label. Colour marking of containers is a secondary method of identifying the hazard group appertaining to the contents and is not to be relied upon as a means of identifying the actual content. There is no common universal standard for container colour coding. Individual nations, manufacturers, etc, generally follow their own national standards. MOD Policy is to comply with BS EN for precautionary labels and BS EN for colour coding. 13

16 SECTION 2 GROUND CONTAINERS 8 GENERAL REQUIREMENTS 8.1 Contractor owned containers Contractor owned transportable gas containers shall be stamp marked in accordance with the requirements of BS ISO 13769, labelled in accordance with the requirements of BS EN and the Restructured ADR, and colour-coded in accordance with the requirements of BS EN In addition, in order to meet the requirements for Aircraft Cross-Servicing, Ground Containers containing gases to be used in servicing aircraft shall be labelled with the appropriate NATO Code Number and NATO Gas Name in accordance with Table E-1. Note: this may be achieved by the use of a separate label, by adding this additional information to the labels required by BS EN , or by paint stencilling. Note: Sub-clause 8.2 and Clauses 9, 10, 11 and 12 do not apply to Contractor owned containers. 8.2 MOD owned Ground Containers MOD owned transportable containers shall be stamp marked in accordance with Clause 9; colour coded in accordance with Clause 10, be fitted with a Next Test Date disc in accordance with Clause 11 and stencilled in accordance with Clause 12. In addition, a precautionary label in accordance with the requirements of BS EN and the Restructured ADR shall be firmly attached to the container. This label shall, as a minimum, identify the contents with the appropriate coloured Hazard diamond, the UN Number, the Proper Shipping Name of the gas or mixture, and the UN Class Number. (See Annex B). In order to meet the requirements for Aircraft Cross-Servicing, containers containing gases to be used in servicing aircraft shall be labelled with the appropriate NATO Code Number and NATO Gas Name, in accordance with Table E-1. Note: this may be achieved by the use of a separate label, or by adding this additional information to the labels required by BS EN , or by paint stencilling. 9 STAMP MARKING 9.1 General Stamp marking shall be applied on the container shoulder unless a non-ferrous stamping ring is fitted, and is to contain the information detailed at 9.3 or 9.4, as appropriate for its intended application. 14

17 SECTION 2 GROUND CONTAINERS Containers obtained prior to 1 st July 2003 shall comply as a minimum with the pre column of Table 1 or 2, as appropriate.

30 SECTION 3 AIRBORNE CONTAINERS 13 GENERAL REQUIREMENTS The use of airborne high pressure containers is subject to various constraints regarding container life, the number of cycles in which the container can be filled and discharged and to reconditioning requirements (see Def Stan ). Clauses 14, 15 and 16 detail various requirements for stamp marking, marking colours, stencilling and labelling of containers. In addition a system of coding with coloured spots is employed to indicate container life-extension and reconditioning status (see Tables 12, 13 and 14). Clauses 14, 15 and 16 identify the markings found on existing containers that were applied prior to February 2004 and detail those that meet the requirements of the Restructured ADR. Most airborne containers were manufactured to specifications provided by aircraft and cylinder design authorities, Def Stan , or earlier versions such as Ministry of Aviation specifications, which are not recognised by the Restructured ADR and TPED. However the marking of these items should as far as practicable, comply with the requirements of the Restructured ADR. Any stamping, stencilling, painting or labelling applied to airborne containers post issue of this Def Stan are to be, as far as practicable in the format specified by the Restructured ADR as specified in Tables 10 to STAMP MARKING 14.1 General Stamp marking shall be applied either on the non-ferrous neck collar provided for the purpose or on the container shoulder or both, unless otherwise approved by the Engineering Authority, and is to contain the information detailed at 14.3 and Size For sizes of stamped markings see

41 SECTION 4 DIVING CONTAINERS 19 MARKING COLOURS For Containers obtained since 1 st July 2003, the container colour, shoulder or band colour(s) and position(s) where appropriate, shall be as specified in Table 19. The shoulder colour(s) and width of the band(s), if any, shall be in accordance with BS EN Table 20 specifies the container colour, shoulder or band colour(s) and position(s) that were used on Containers obtained prior to 2003 (to BS 349 standard). Some of these marking colours are not compliant with the requirements of BS EN and when next refurbished these containers shall be re-marked in accordance with Table REFERENCE TO NEXT TEST DATE The next test date (Year/Month, e.g. 2006/05) shall be clearly indicated on the container by means of stamping, engraving, a durable label, or a disc fitted between the valve and the container. To provide consistency between MOD owned containers and European Standards for period inspection and testing of transportable gas containers, the use of Next Test Date Discs is preferred, as specified in the, now withdrawn, BS 5430 series of standards and their ISO replacements. Where ever practicable, these discs should be incorporated during the next refurbishment cycle. (See Annex F). 21 STENCILLING REQUIREMENTS 21.1 General Precautionary labelling shall be provided by means of stencilling as detailed in 21.3 or 21.4, as appropriate.

50 SECTION 6 FIVE NOTES APPLICABLE TO SECTIONS TWO, THREE, FOUR AND Note Description 1. The requirement for the Government property mark i.e. pheon or broad arrow,, is to be in accordance with Section C(4) of Def Stan The stamped NATO stock number, or service reference number, shall be marked on the shoulder close to the neck or on the non ferrous ring, except for acetylene containers, and shall be that of the bare container, i.e. unpainted and un valved but with collar, if fitted, and metallized where required. For Airborne containers also see Note The UN Model Regulations specify the date of the initial inspection shall be a fourdigit year code followed by a / and then a two-digit month code. 4. The stamped or stencilled tare is that of the empty container with its permanent fittings, e.g. collar, if fitted, metallized, painted and valved. 5. For Stamp Marking this shall consist of an inspection stamp and a date of periodic inspection, in the form of a two-digit year code followed by a / and then a two-digit month code. (See also Note 3). 6. The stencilled NATO stock number on the container shall be that number allocated for the container in its filled condition, i.e. complete with collar, if fitted, painted, and valved. 7. For containers for gases of special purity the gas name shall be marked as stated in the contract or other requisitioning document. 8. Airborne containers for breathing oxygen shall be marked by the inscription OXYGEN-AV and O 2 AV. Containers for compressed breathing air shall be marked by the inscription AIR BREATHING. 9. Airborne containers for breathing oxyge n shall be marked by the symbol of two horizontal filled rectangles, black on a white background (see Def Stan 05-18). 10. For containers filled with a charging pressure > 300 bar only. It is to be stencilled in red both sides; on a white band adjoining the shoulder. 11. Actual percentage figures (by volume) to be stencilled in. 12. Material identification letters, NCM, CM, Mn and C, shall be used for nickel chrome molybdenum, chrome molybdenum, manganese steels and carbon steel respectively. For existing aluminium alloy containers made from BS L 105, BS L 111, or BS 1474: HE 30 TF the material identification marks are to be L 105, L 111, or HE 30, respectively. NOTE: Some of these standards have been withdrawn, i.e. BS L 111 has been replaced by BS EN 2326, but still remains current. BS 1474 has been withdrawn and superseded and should not be invoked when procuring new containers. 48

51 SECTION 6 FIVE NOTES APPLICABLE TO SECTIONS TWO, THREE, FOUR AND 13. Gas capacity for airborne containers shall be calculated for the gas in question, i.e. not nominal. 14. This is the pressure, at 15 C (20 C for airborne containers) to which the container should be charged, and is to be adjusted for other temperatures in accordance with BS The mass is for the container with collar, if fitted, metallized, painted, valved and filled. 16. The presence of a siphon tube fitted in a container shall be indicated by a line at least 12 mm wide in the designated stencilling colour painted on the container. A stencilled line along the length of the cylindrical section shall indicate a full-length dip tube. A gooseneck eductor tube shall be indicated by a stencilled line on the shoulder of the container. 17. After satisfactory completion of the periodic inspection and test, the suffix V, where applicable, shall be used to indicate visual examination only and shall be located after test date. Note: This requirement is only applicable to BS 5430, Part 1:1990, container designs whereby some containers, such as those used for self-contained underwater breathing apparatus, are required to be Visually Examined midway through the hydraulic test interval. 18. Carbon dioxide containers used for airborne life raft purposes may be painted white with black stencilling to minimise their heat absorption propensities. 19 Wire-wound airborne gaseous containers that used a non acid flux in the winding process, are to be marked by a 25mm white spot on the shoulder away from the other markings or where space allows. White painted containers are to be designated with a 25mm black spot. At the next reconditioning such containers are to be marked with a second spot close to the first. 20. If reconditioning is carried out by any organisation other than the manufacturer this marking will not be transferred when a brass collar is replaced. 21. Contractors undertaking reconditioning of containers shall: a. Remove, obliterate or otherwise cancel any yellow spot or date legend previously stencilled on containers. b. Re-mark any date of initial charge, date of reconditioning, date of first charge after reconditioning (if applicable) or green or white or black spots which are perforce removed or obliterated as part of the reconditioning process. 22. The contractor shall stamp the drawing or part number of the container. If there is insufficient space, the drawing or part number shall take precedence over the NATO stock number. 23. Settled Working Pressure, bar, at 15 C. 49

52 SECTION 6 FIVE NOTES APPLICABLE TO SECTIONS TWO, THREE, FOUR AND 24. NDT test codes are: UT = Ultrasonic test; MT = magnetic particle test; PT = dye penetrant test; AT = acoustic emission (see BS ISO 13769). 25. Steel containers and composite containers with steel liners intended to be used for hydrogen and other gases possessing a risk of hydrogen embrittlement (see BS EN ISO , Groups 2 and 10) shall be stamp marked with an H denoting compatibility of the steel. HG is for high grade stainless steel containers or liners. 26. The Maximum Permissible Filling Weight is the product of the Water Capacity of the container and the filling ratio of the gas. If it is stamp marked on the container it shall be followed by the letters KG and the name or chemical formula of the gas. 27. The TARE weight is the sum of the Empty weight, the mass of the valve (and dip tube if fitted), valve guard, the paint and other permanently fitted parts. 28. Pi Marking of containers has been mandatory since July However TPED will not be fully implemented until 1 st July 2006, followed by a 24 month period, when all containers will have to be periodically inspected by a body approved by the Competent Authority (see Figure A.1). 29. This mark is not mandatory for composite containers or containers with a water capacity of one litre or less. 30. This is a mandatory requirement for composite containers. 31. The Country of Approval of the Inspection Body. Identified by using the motor vehicle International Identity Symbol, e.g. GB (see BS EN ISO ). 32. The stamp mark only needs to precede the Manufacturers identity stamp when the Country of Manufacture is different from the Country of Approval. 33. HSE, HID, Offshore Division, Diving Operations Strategy Team recommendations to the Diving Industry are that containers used in underwater breathing apparatus require a full internal visual inspection mid-way between the full-test interval (sometimes known as periodic inspection and test ). After satisfactory completion of the periodic inspection and test, the suffix V, where applicable, shall be used to indicate visual examination only and shall be located after test date. Note: this is not a requirement imposed of BS EN 1968:2002 (see also Note 17). 34. If there is insufficient space available on the collar to accommodate all required stamping this marking may be omitted. 50

57 SECTION 8 ANNEXES A STAMP MARKING: RESTRUCTURED ADR A.1 Stamp Marks A.1.1 The UN Model Regulations and the Restructured ADR classify Stamp Markings into one of three named groups, i.e. Certification Marks, Operational Marks, and Manufacturing Marks, plus Other Marks. A.1.1 The Regulations require that the three named groups of markings be placed in group-sequence and sequence: with Manufacturing Marks placed in the top band nearest to the valve; Operational Marks are placed in the middle band; and, Certification Marks placed in the bottom band. (see also BS ISO 13769). A.1.2 Other Marks such as the date of the last periodic inspection, the inspection body, NATO stock numbers, etc, may be placed, other than the side walls, in low stress areas, provided they do not create harmful stress concentrations, and provided they do not conflict with the Manufacturing, Operational and Certification Marks. A.1.3 Manufacturing Marks include, in sequence: identification of the container thread; the Manufacturer s Mark; the serial number; and, the compatibility mark H, if applicable. A.1.4 Operational Marks include, in sequence: the test pressure, preceded by PH ; the empty mass, followed by KG ; the minimum guaranteed wall thickness followed by MM ; for liquefied gases, the water capacity in litres followed by L. A.1.5 Certification Marks include, in sequence: the UN Mark, the design standard, the Country of Approval, the initial inspection mark and the date of initial inspection. A.1.6 Other Markings include the date of the last periodic inspection, the inspection body, and various markings required by the owner, such as the MOD pheon, NATO stock numbers, etc. A.2 Pi Mark The approved style of the Pi mark is given in Figure A.1. 55
