ASTM D4495-16

Standard Test Method for Impact Resistance of Poly(Vinyl Chloride) (PVC) Rigid Profiles by Means of a Falling Weight

SIGNIFICANCE AND USE
5.1 The impact strength of PVC profiles relates to suitability for service and to quality of processing. Impact tests are used for quality-control purposes and as an indication that products can withstand handling during assembling, installation, or in service.  
5.2 Results obtained by use of this test method are used in two ways:  
5.2.1 As the basis for establishing impact-test requirements in product standards, and  
5.2.2 To measure the effect of changes in materials or processing.
SCOPE
1.1 This 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.  
1.2 This test method is used either by itself or in conjunction with other methods for measuring PVC product toughness.  
1.3 Because 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.  
1.4 The 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.  
1.5 The values stated in inch-pound units are to be regarded as the standard.  
1.6 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: There is no known ISO equivalent to this standard.

tip of the crack have a greater than 0° angle), or ductile breaks (hinged breaks where the cracked part remains joined to the
unbroken part throughout the length of the cracked part or section), (Fig. 1).

3.2.4 outlier—an observation that appears to deviate markedly from other members of the sample in which it occurs.
4. Summary of Test Method
4.1 The profile is cut into lengths of at least 6 in. The test method establishes the height from which a standard falling weight
will cause 50 % of the specimens to fail.
