14、osslinked rubber nonmetallic semi-conducting or insulatingcompound. The compound shall be well, evenly, and smoothlyprocessed, cut to the specified widths, and tightly wound inrolls with a separator between layers. Where a non-removableseparator is used, the separator will be considered an integralp
15、art of the tape.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 Insulation Materials.Current edition approved March 10, 2002.

17、le material interposed betweenadjacent layers. The removable or non-removable 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 insulatio
18、n. The outside end of the roll shallbe securely fastened.4.3 Rubber tapes shall conform to the requirements of Table1.5. Permissible Variations in Dimensions5.1 The tape shall conform to the nominal dimensions foundin Table 2 when tested in accordance with Test MethodsD 4325.5.2 The average thicknes
19、s shall not vary from the nominalthickness by more than 60.076 mm (60.003 in.) and theaverage width by more than 60.76 mm (60.03 in.).5.3 The average length of the rolls in any sampling shall beno less than the nominal length.6. Aging and Storage6.1 Tapes shall not become unduly attached to the sepa
20、ra-tors within the period of time specified in Table 3. They alsoshall meet the fusion test as specified in Test Methods D 4325when applied at the elongations specified for each type.6.2 Store the tape in the original boxes, preferably in a cooldark location. Do not keep tapes in close proximity to
21、steampipes, radiators, or other sources of heat.7. Test Methods7.1 Select rolls, conditioning, and testing in accordance withTest Methods D 4325.7.2 Unless otherwise stated, measurements are made ontapes from which the removable separator has been removed.8. Rejection and Retest8.1 If only one sampl
22、e roll fails to meet the specification,take a second set of samples in accordance with Test MethodsD 4325. Failure of two sample rolls constitutes grounds forrejection.9. Inspection9.1 Inspection of the material shall be made as agreed uponby the purchaser and seller as part of the purchase contract
23、.9.2 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.TABLE 1 Physical Properties for Rubber Insulating TapeRequirements Type I Type II Type III Type IV Type VTensil
