Materials and Manufacture4.1 The tape shall consist of a woven fabric sheetingimpregnated with an adhesive insula

6、ting compound, cut intorolls of narrow width and wound on a core.4.2 The fabric sheeting shall be evenly and firmly wovenand as free of unsightly defects, dirt, knots, lumps andirregularities of twist as is consistent with the best manufac-turing practices. The threads shall run in lines as straight

7、 aspossible without weaving, to reduce to a minimum the ravelingof the cloth when cut into tape.4.3 The frictioning compound shall be a tacky adhesiveinsulating compound that will not have a deteriorating effect oncopper or other metals or on the fabric.4.4 The fabric shall be thoroughly impregnated

8、 and evenlycovered on both sides with the frictioning compound. Thecompound shall adhere firmly to the fabric and shall not pullaway from the fabric and leave bare spots when adjacent layersof tape are separated.5. General Requirements General Requirements5.1 Friction tapes shall meet the requiremen

9、ts given in Table1 when tested in accordance with Test Methods D69.5.2 When discoloration of the surface on which the tape isto be applied is an important consideration, the purchaser mayrequest that the tape must pass the test for discoloration ofcopper in accordance with Test Methods D69.6. Dimens

10、ions and Permissible Variations6.1 The nominal dimensions and their permissible varia-tions when measured by the procedures of Test Methods D69are presented in Table 2.7. Test Methods7.1 The selection of the rolls, conditioning, and testing shallbe in accordance with Test Methods D69.8. Inspection8.

Rejection9.1 The purchaser reserves the right to reject any part of theshipment that does not comply with Section 11 of thisspecification.9.2 The purchaser reserves the right to reject a shipmentfrom which two or more sample rolls fail to meet therequirements

17、 of any individual test or measurement prescribedin this specification, without additional sampling. If only onesample roll fails an individual test or measurement or theaverage length of the sample rolls exceeds the prescribedvalue, a second set of samples shall be taken in accordancewith Test Meth

18、ods D69, and all rolls in the second samplingshall be subjected to that test or measurement wherein thefailure occurred. The purchaser reserves the right to reject theshipment if the second sampling fails to conform with theapplicable requirement.10. Aging and Storage10.1 The tape shall at any time,

19、 within eight months afteracceptance if stored in accordance with 10.2, meet the adhesiontest specified in Test Methods D69 except that a force of 3lbf/in. (13.3 N/25 mm) shall be substituted for the 4 lbf/in.(17.8 N/25 mm) during unwinding.10.2 Proper storage of tape requires the use of the origina

20、lboxes and a cool, dark location. Tape shall not be stored nearsteam pipes, radiators, or other sources of heat.11. Packaging and Package Marking11.1 Unless otherwise specified, the tape or carton shall besecurely wrapped and sealed in a moisture-proof material toprotect its contents.12. Keywords12.
