INSPECTION, TESTING AND FREQUENCY Clause Samples

INSPECTION, TESTING AND FREQUENCY. The sampling should be carried out by competent staff and testing must be carried out by a Laboratory that is UKAS accredited. All testing required in the testing matrix must be a UKAS accredited test, unless agreed with the YHAUC Recycling Group. The laboratory will update the recycled material database on the YHAUC web site accordingly. (See Appendix 5 for the list of accredited Laboratories and appendix 4 for the table of testing requirements.) All material sampling must be carried out to the current prescribed standard and undue delay in testing avoided. Any manufacturer’s recommendations on sample preparation and storage must be considered as good practice. Note: Some enhanced products require specific early life testing. This framework requires testing to be carried out in accordance with Appendices 4.1 and 4.2 and must conform to the WRAP Protocol. The YHAUC Recycling Group reserve the right to alter the testing requirements and frequencies, this will be agreed with suppliers on an individual basis. Categorisation System – (“Traffic Light System”) Each test result is checked against the specification and classified into a category with limits relating to that specification. This enables the “Engineer” to quickly assess a particular sample. When reports are received, a look through the category classification or colour coded boxes on the report will quickly highlight which reports need extra attention. = “A” Generally if the material falls into the “A” Category or “green box” then the material is within specification for those tests undertaken on the material delivered and provided it is laid correctly, should present no problem. = “B” Materials falling into the “B” category or amber box can again be considered satisfactory and which in practice will give no significant difference in performance between it and a category “A” material as they are marginally out of specification and generally fall within the limits of repeatability. = “C” Materials which fall into the “C” category or red box require extra attention as the test result indicates that there may be something wrong with the material. The sample of material may be far enough outside the specification limits so that the performance of the material may be adversely affected. Not all results which fall into this category can be regarded as unacceptable. Each result has to be examined in the area where it is out of specification and in its intended use with a judgment made by the client in conju...
