    4. INSPECTION AND TESTING

    a. Unless otherwise stated in the tender, the manufacturer is to supply Q&PS twosamples of size 300mm 300mm for the carpet being offered in the correctdesigns and colours, together with material characteristics showing that all therequirements specified in this NES are complied with.

    b. Carpet rolls may be subject to inspection by the Q&PS (QA Authority) namedin the contract. The QA Authority may request that samples be taken from anypart of a consignment and checked, in his presence, for compliance with thisNES. Any material failing to meet these requirements will be rejected and maycause the whole consignment to be rejected.

    c. The first manufacturing batch is to be tested in accordance with Annex C., D.,E., F. or G. as relevant to the type of carpet being supplied. Further testing isnot required unless a change in the production technique results in a change (orchanges) to the material characteristics of the carpet.

    5. IDENTIFICATION AND PACKAGING

    a. A label bearing the Batch Number, Contractors Name, Length, Width, PatternNumber, Description, Dyelots and any other markings as required by thecontract, is to be attached to each roll (or piece) of carpet on the outerwrappings. Informative labelling is also to comply with BS 3655.

    b. Carpets are to be supplied wrapped in virgin, non-slip, anti-static, A gradepolyethylene sheeting of 400g/m2, sealed with amicro-vinyl clear tape 35mm inwidth, to prevent contamination by dust or flooding. Should the wrapping befound to be damaged upon receipt from the manufacturer, the roll may berejected.

    c. The packaging is to be of such quality that delivery of goods in undamagedcondition is ensured.
