8、fic to This Standard:3.2.1 dispensabilitythe initial force and elongation re-quired to sever or cut off a strip of pressure-sensitive film tapefrom a roll using specific test conditions and specific bladedescribed in this test method.4.Significance and Use4.1 Pressure-sensitive film tapes are suppli
9、ed in roll form.For such a tape to be useful a strip of the tape must be easilydispensed or severed from the roll by means of a cutter foundon most dispensers.This test method is a means of measuringthe ease of this severing or dispensing of the tape.4.2 This test method provides information that ca
10、n be usedin material specifications for product design and qualityassurance applications.It can be used in comparing differenttape products on specific dispensing blades.4.3 This test method may be suited for office and stationeryand tapes with acetate,cellophane,or light-duty plastic back-ings.Some
11、 tapes may be shown to be difficult to dispenseunder these conditions yet are readily dispensable with otherdispensing systems.NOTE1Backings described in CID A-A-113 are typical backings.5.Apparatus5.1 Tension TesterA constant-rate-of-extension(CRE)type with load cell capacity such that the maximum
