19、ufacturer shall set up a quality control programto inspect the product throughout the manufacturing process.Each production lot shall be marked or coded to identify thedate of manufacture. The Quality Control Program shall haveprovisions to identify and set aside any material or finishedproduct that
20、 appears defective and does not meet this specifi-cation.7.4 Third party inspection for Quality Control ProgramCertification shall be made at a minimum of once per quarter.These inspections shall occur without notice at anytime theplant is in operation.

Production Quality Control Requirements8.1 Sampling:8.1.1 Breaking Load TestA minimum of one te
22、st speci-men per 500 m2(5382 ft2) exposed area of merchantablematerial produced shall be randomly selected from a consistentstage in the manufacturing process and tested for breaking loadas defined in 8.2.1.8.1.2 Water Absorption TestA minimum of one test speci-men per lot of merchantable material p
23、roduced shall berandomly selected from a consistent stage in the manufacturingprocess and tested for water absorption as defined in 8.3.8.2 Mechanical Requirements:8.2.1 Breaking Load Test ProcedureEach test specimenshall be centered on two parallel metal supports, having aradius of 13 mm (12 in.),
24、which shall be free to rotate (see Fig.1). The center-to-center distance between the supports shall be254 mm (10 in.). A load shall be applied at the center of thespan, with a metal bar of 13 mm (12 in.) radius, be parallel tothe two parallel metal supports, and be in contact with the testspecimen o

The failing load for each test specimen shall berecorded to the nearest9N(2lbf). Test results shall berecorded as N (lbf).8.2.2 Precision and Bias:8.2.2.1 PrecisionThe precision of
26、 the procedure in thisstandard for breaking load test is being determined.8.2.2.2 BiasSince there is no applicable reference mate-rial to determine bias for the breaking load test, no statement ofbias is being made.8.2.3 Condition of AcceptanceThe breaking load shall bea minimum of 312 N (70 lbf) fo
