8、d (see 6.4 and 6.5). 3.2 Bid sample and laboratory report approval. Unless otherwise specified (see 6.2), at the time of submission of a bid, the bidder shall submit to the contracting officer a sample of 15 yards and a certified copy of a recent laboratory report covering the cloth which he propose
9、s to deliver. Unless other- wise specified by the contracting officer, the bidder shall certify that the sample submitted was manufactured using the facilities and processes he proposes to use in the manufacture of the cloth. This laboratory report shall contain test data which demonstrate that the
10、finished cloth which the bidder proposes to deliver has been tested, and the extent to which the cloth complies with the performance requirements of this specification (see 6.7).
