15、the separator between the StandardNumber and the Type. Separators are not needed between theType, Grade, and Class.5Provision for Special Notes isincluded so that other information can be provided whenrequired. An example would be in Specification D3295 81awhere dimensions and tolerances are specifi

16、ed for each AWGsize within Type and Class. When Special Notes are used, theyshould be preceded by a comma.5. Requirements5.1 The sheet and film shall be manufactured from poly-chlorotrifluoroethylene (PCTFE) plastics that consist of at least90 % chlorotrifluoroethylene. The remaining 10 % may in-clu

17、de chemical modifications, such as co-monomers, but notcolorants, fillers, plasticizers, or mechanical blends of otherresins.5.2 The length, width, roll core diameter, and maximumnumber of splices permitted shall be as agreed upon betweenthe purchaser and the seller. The tolerance for roll width sha

18、llbe 3 mm (18 in.). 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
