ASTM D4495-16

1.1This test method covers the determination of the energy required to crack or break rigid poly(vinyl chloride) (PVC) profile under specified conditions of impact by means of a falling weight.

1.2This test method is used either by itself or in conjunction with other methods for measuring PVC product toughness.

1.3Because of the wide variety of profile sizes and shapes and the wide variety of manufacturing procedures and field abuse, this test method does not correlate universally with all types of abuse. Therefore, correlations must be established as needed.

1.4The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this standard.

1.5The values stated in inch-pound units are to be regarded as the standard.

1.6This 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.
