2 /0/0 ISO WORK PROGRAM Which documents are in preparation? Standard for Terms and Definitions 8 Documents about Human Factors Performance Standards (Filtering - and Supplied breathable gas RPD) Standard for Thread Connector (Filter & RI) 5 Test method Standards Standards for Selection & Use 0 Documents WEARER FOCUS AND SYSTEM APPROACH What is wearer-focus? ISO-RPD- Standardization follows the W e a r e r focus based on Human Factors for protection against all threats of working environment Environment Protection wearer ISO-RPD- Standardization is based on a System Approach exception: Filter and Respiratory Interface with Standardized Connector Protection Performance Characteristic will tie into Classification Hazards and a selection procedure will use the appropriate class of R Leonardo da Vinci 5-59 RPD with the adequate performance

3 /0/0 NEW APPROACH Change in concept: What is new? from product orientated standardization. P e r f o r m a n c e to from more than 0 RPD-Product-Standards to only main RPD-Standards! ISO 70, Supplied Breathable Gas RPD, ISO 70 /, Filtering RPD/Thread to performance orientated standardization! PERFORMANCE CHARACTERISTICS OF RPD What are Breathable Gas Capacity Total Inward Leakage typical Work Rate Performance Characteristics? Particle Filter Type/Efficiency Work of Breathing Gas Filter Type/Capacity Breathing Resistance

Human Factors Thermal Effects part 5 Work of Breathing part Human ISO 6976 Factors CO -O limitation part Hearing Psycological Ergonomics & Speech Effects part 8 part 7 part 6 Metabolic Rates part Anthropometrics part are the foundation of the ISO RPD Standardization DEFINITION OF WEARER GROUP Who are the wearer? Definition of wearer group: 5 to 95 perzentile, based on the Gauss Distribution of all RPD wearers, female and male, in the age of legal employment in their working environment std.normv( m = 5,00; s =,00 ), 0,8 0,6 0, 5 % (female) 95 % (male) 0, % 5 % to 95 % R ISO/TC /N00 Definition of Virtual Human Body

6 /0/0 MINUTE VENTILATION & WORKRATE CLASSES How much breathable gas does the wearer needs for his/her task? The minute ventilation and the designated work rate classes [W] W: maximal 5 l/min (5 [/min] x [l] ) for 5 minutes only W: extremely heavy 05 l/min ( [/min] x,5 [l] ) W: very heavy 65 l/min (,5 [/min] x [l] ) W: moderate 5 l/min (, [/min] x,5 [l] ) 6976 Metabolic Rates part barrier line class e Body (Suit) d Head (Hood) c Face (Full Face mask / visor) b Mouth and Nose (Half mask) a Mouth only (Mouth piece) a Nose only CLASSES OF BARRIER LINES & PROTECTION LEVEL What are the new classes for Respiratory Interfaces?

9 /0/0 ALLOWED CONFIGURATION Respiratory Interface: part of the system but with additional requirements as component on its own, when standardised connector according to ISO 70 is used Consequences of the exception RI - Thread Connection - Filter: No ISO-Thread Connection for Supplied Breathable Gas Devices with negative pressure mode RPD system Why: the RI with -marking has only limitation on peak pressures, no dynamic interface characteristics specified, performance charateristic of LDV is not supported in all possible cases 9

10 /0/0 SELECTION -USE - MAINTENANCE ISO Respiratory Protective Devices-Selection, Use and Maintenance RPD spec Risk Hazard Assessment How to select the adequate and suitable RPD for your application/task? Suitability Assessment Assessment Adequacy Assessment WORK ITEM CONTROL PLAN ISO 70- SBG-RPD When will the new ISO-Standards been published?.0.0 st Committee Draft 0 07 voting - delay 0 month nd CD 09 Draft International Standard (DIS) 0 target Final DIS Publication new target 0

11 /0/0 05 future ISO Standards todays EN Standards CHANGEOUT PROCESS. review revision? Transition periode: after y years IS decision: go EN ISO up to5 years prepare new EN xxx Standards remaining issues How and when will ISO affect European Market? new EN xxx covering remaining issues EN ISO Standards CE Certification: - based on EN - based on EN ISO prepare Annex ZA -Document CE Certification based on PPE- Directive & ISO Standards STANDARDIZATION TRENDS Why does the wearer need a new standard? because wearer needs to know which performance level of an RPD is the most adequate for the application/task to protect them because wearer needs support in establishing and implementing a RPD program through recognized industrial standards because wearer needs help in selecting the adequate and suitable RPD because the harmonised classification system allows waerer to compare performances amongst RPD types

12 /0/0 DELOYMENT IN STANDARIZATION Why do we need new ISO-Standards for RPD? because there are no International Standards for RPD existing worldwide because there is a need to define and establish equal protection levels for wearers in any workplace regardless of world s location because gaps of existing standards have to be closed The protection of the wearers is in the focus of ISO RPD and that is called: Human Factors driven standardization! Why does the world need new ISO-Standards? because ISO Standards have a good chance to remove barriers to world trade! I S O R P D for a better protection
