While equipment may be operated at temperatures exceeding 525 OF to accomplish a satisfactory seal, the barrier material should also be capable of being heat-sealed at temperatures of 525

45、OF or less. 6.4 First article test samples. Samples for first article inspection should consist of a sample of the barrier material which has been produced by the contractor using the same production process, procedures, and equipment that is going to be used in fulfilling the contract. 6.5 Conforma
