Materials and Manufacture4.1 The tape shall consist of a woven fabric sheetingimpregnated with an adhesive insulating compound, cut intorolls

6、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 aspossible without weaving,

7、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 and evenlycovered on both si

8、des 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 Requirements5.1 Friction tapes shall meet the requirements given in Table1 when tested in accordance with

9、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. Dimensions and Permissible Variations6.1 The nominal dim

10、ensions 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. Inspection8.1 Inspection of the material shall be made as agre

11、ed uponbetween the purchaser and the seller as part of the purchasecontract.8.2 If it is required, the tape shall be tested and inspectedeither at the place of manufacture prior to shipment or at theplace of delivery within four weeks from the date of delivery.9. Rejection9.1 The purchaser reserves

12、the right to reject any part of theshipment that does not comply with Section 11 of thisspecification.1This specification is under the jurisdiction of ASTM Committee D09 onElectrical and Electronic Insulating Materials and is the direct responsibility ofSubcommittee D09.07 on Flexible and Rigid Insu

United States19.2 The purchaser reserves the right to reject a shipmentfrom which two or more sample rolls fail to meet therequi

16、rements 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 Te

17、st Methods 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 an

18、y time, 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

19、originalboxes and a cool, dark location. Tape shall not be stored nearsteam pipes, radiators, or other sources of heat.11.
