17、temperature of 10and 40 C (14 and 104 F).5. Physical Properties5.1 The tape shall consist of a non-crosslinked or partiallycrosslinked rubber nonmetallic semi-conducting or insulatingcompound. The compound shall be well, evenly, and smoothlyprocessed, cut to the specified widths, and tightly wound i

18、nrolls with a separator between layers. Where a non-removableseparator is used, the separator will be considered an integralpart of the tape.5.2 The separator shall be parchment paper, glazed orplastic sheeting, or any suitable material interposed betweenadjacent layers. The removable or non-removab

19、le separatorshall not interfere with the use of the roll during application.Where a removable separator is used, the separator shall bereadily removable from the rubber insulation without tearing ordamaging the tape insulation. The outside end of the roll shallbe securely fastened.5.3 Rubber tapes s

20、hall conform to the requirements of Table1.6. Permissible Variations in Dimensions6.1 The tape shall conform to the nominal dimensions foundin Table 2 when tested in accordance with Test MethodsD4325.6.2 The average thickness shall not vary from the nominalthickness by more than 60.076 mm (60.003 in

21、.) and theaverage width by more than 60.76 mm (60.03 in.).6.3 The average length of the rolls in any sampling shall beno less than the nominal length.7. Aging and Storage7.1 Tapes shall not become unduly attached to the separa-tors within the period of time specified in Table 3.7.2 Store the tape in

22、 the original boxes, preferably in a cooldark location. Do not keep tapes in close proximity to steampipes, radiators, or other sources of heat.8. Test Methods8.1 Select rolls, conditioning, and testing in accordance withTest Methods D4325.8.2 Unless otherwise stated, measurements are made ontapes f

Rejection and Retest9.1 If only one sample roll fails to meet the specification,take a second set of samples in accordance with Test MethodsD4325. Failure of two sample rolls constitutes grounds forrejection.10. Inspection10.1 Inspection of the m

24、aterial shall be made as agreed uponby the purchaser and seller as part of the purchase contract.10.2 If inspection is required, the tape shall be tested andinspected either at the place of manufacture prior to shipmentor at the place of delivery within four weeks from date ofdelivery.11. Packaging

25、and Package Marking11.1 PackagingUnless otherwise specified, the tape orcarton shall be securely wrapped and sealed in a moisture-proof material to protect the contents.11.2 Package MarkingEach box shall be marked with thename of the manufacturer or trademark, nominal width,thickness, and length of
