The tolerance for roll length shall be 6 10 %of the specified length.5.3 Thickness tolerances shall be as specified in Table 1.5.4 The sheet and film shall conform to the property valuesspecified in Table 2, Table 3, and Table 4.5.5 The material shall be essentially free fromcont
19、amination, wrinkles, holes, scratches, and other imperfec-tions unless otherwise agreed upon between the purchaser andthe seller.6. Sampling6.1 Sampling shall be statistically adequate to satisfy therequirements of 10.4.7. Number of Tests7.1 One set of test specimens as prescribed in Section 8shall
20、be considered sufficient for testing each batch. Theaverage result of the specimens tested shall conform to therequirements of this specification.8. Specimen Preparation8.1 ConditioningFor those tests where conditioning isrequired, condition the test specimens in accordance withProcedure A of Practi
21、ce D618 for a period of at least 24 h priorto test.8.2 Test ConditionsUnless otherwise specified, conducttests at the Standard Laboratory Temperature of 23 6 2C (70to 77F) and at 50 6 10 % relative humidity.8.3 Preparation of SpecimensTake test specimens acrossthe width of the roll.9. Test Methods9.
22、1 ThicknessMeasure the sample across the web width at25-mm (1-in.) increments. All readings shall be within thespecified tolerances. Abnormal readings may occasionallyresult from spot imperfections. Discard such readings and takenew readings in the same area (excluding the defect).9.2 Tensile Streng
