1.1This test method covers the determination of the shrink tension and related characteristics, that is, shrink force and orientation release stress, of heat-shrinkable plastic film and sheeting of less than 1.0 mm (0.04 in.) thickness. Two procedures are described that permit the measurement of shrink forces at predetermined temperatures. They are as follows:
1.1.1Procedure Ais designed to measure the maximum force exerted by a specimen that is totally restrained from shrinking as it is heated rapidly to a specific temperature.
1.1.2Procedure Bis designed to measure the maximum force exerted by a specimen that is permitted to shrink a predetermined amount prior to restraint while being heated rapidly to a specific temperature.
1.2Orientation release stress can be determined from the data obtained using Procedure A.
1.3The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
1.4This 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 and health practices and determine the applicability of regulatory limitations prior to use.
Note 1:Film has been arbitrarily defined as sheeting having nominal thickness not greater than 0.25 mm (0.010 in.).
Note 2:There is no known ISO equivalent to this test method.
