40、rab test method described in Method 5100 ofFED-STD-191 with the following exceptions: The test sampleshall be from 12 to 14 in. long by the full width of the felt. Fivetest specimens measuring 12 in. in the width direction by 12 to14 in. (305 by 355 mm) long shall be cut from the sample. Thespecimen
41、s shall be clamped at the top and bottom sections bya nominal12 in. (12 mm) pipe covered with 0.25-in. (6-mm)thick sponge rubber to prevent cutting and slipping of thespecimens. The clamped specimens, having a test area of about1ft2(0.09 m2) shall be attached to the grips of the testingmachine that
42、shall separate at a rate of 2 6 0.2 in. (51 6 5mm)/min until rupture occurs.

The tensile strengthshall be expressed in pounds per square inch (kilopascals)based on the n
43、ominal cross-sectional area.

45、the purchaser in the contract ororder, the certification of an independent third party indicatingconformance to the requirements of this specification may beaccepted instead of the manufacturers certification.17.3 In case of rejection, the manufacturer or supplier shallhave the right to reinspect th
46、e rejected shipment and resubmitthe lot after removal of the portion of the shipment notconforming to the specified requirements.18. Certification18.1 When specified in the purchase order or contract, theproducer or the supplier shall furnish a certificate to thepurchaser that the material was manuf
47、actured, sampled, andtested or inspected in accordance with this specification andhas been found to meet the requirements. The supplier shallfurnish a summary of the documentation of the qualificationtest results or the inspection test results, or both, upon request.19. Packaging and Package Marking
