【国外标准】 Standard Test Method for Dispensability of Light–Duty Pressure–Sensitive Film Tape (Withdrawn 2023)

4.1 Pressure-sensitive film tapes are supplied in roll form. For such a tape to be useful a strip of the tape must be easily dispensed or severed from the roll by means of a cutter found on most dispensers. This test method is a means of measuring the ease of this severing or dispensing of the tape.4.2 This test method provides information that can be used in material specifications for product design and quality assurance applications. It can be used in comparing different tape products on specific dispensing blades.4.3 This test method may be suited for office and stationery and tapes with acetate, cellophane, or light-duty plastic backings. Some tapes may be shown to be difficult to dispense under these conditions yet are readily dispensable with other dispensing systems.NOTE 1: Backings described in CID A-A-113 are typical backings.1.1 This test method covers the measurement of the force and elongation required to dispense pressure-sensitive film tape on a 1-in. core intended for office and stationery applications from a desk-top dispenser.1.2 The values stated in either SI or inch-pound units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
