DIAGRAMS: NOTES: Diagram (1) Diagram (2) Diagram (3) Details of the Spacer Bar Cross Section Details of the Edge Seal Dimension Details of the Georgian Bars Please supply these on separate sheets GENERAL The purpose of the System Description is to fully define the base product covered by the test report. It must be detailed in every aspect such that there is no doubt about the products and components used in its manufacture UNIQUE PRODUCT REFERENCE NO This is a unique reference number associated with this product description document. It is used as the defining reference for the product and will be quoted in test reports and certificates where applicable. BS Kitemark applicants should leave this blank as the Kitemark Licence No. is used. MANUFACTURER This is the name of the company that manufactured the product not the supplier that you purchased the product from. TYPE REFERENCE This is the name and product identifier given by the manufacturer. ALLOWABLE DEFECTS These are separated into two limits: Absolute Limit This is the limit at which you reject units. All units outside this limit must be disposed of, for example, the seal depth may be described as 5mm minimum however, you may wish to allow a seal depth of between 5mm and 4mm for a maximum of 25mm per metre of unit perimeter. Any unit where there is more than 25mm of seal depth between 4 and 5mm must be rejected. You may also wish to allow 3 air cavities up to 3mm in diameter per metre of unit perimeter. Likewise, if 4 air cavities are present or the diameter of any air cavity is greater than 3mm then the unit is rejected. Action Limit This is the limit at which you take action to improve the relevant parameter, for example, you may wish to set an action limit of 10mm for the length of seal with a depth below 5mm. If, during inspection, this limit is observed then you will need to take action to reduce or eliminate the undersized seal depth. Page 5 of 5 Issue Date 1 st Aug 2008
