Standard Test Method for Unrestrained Linear Thermal Shrinkage of Plastic Film and Sheeting
 N D2732

Annotation

This test method covers determination of the degree of unrestrained linear thermal shrinkage at given specimen temperatures of plastic film and sheeting of 0.76 mm (0.030 in.) thickness or less. This test method does not cover shrinkage from loss of solvent in some materials.

The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.

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 and health practices and determine the applicability of regulatory limitations prior to use.

NOTE 1—This standard and ISO 11501 address the same subject matter, but differ in technical content.

Метод стандартной пробы для несдержанного линейного теплового сжатия термопластической пленки и защитного покрытия

Этот метод испытаний покрывает определение градуса несдержанного линейного теплового сжатия при данных температурах экземпляра пластмассовой пленки и защитном покрытии 0.76 мм (0.030 дюйма.) толщина или меньше. Этот метод испытаний не покрывает сжатие от потери растворителя в некоторых материалах.
