This specification covers requirements and test methods for the material, dimensions, and workmanship, and the properties of extruded shapes of rods and bars made from poly(vinyl chloride) (PVC), and chlorinated poly(vinyl chloride) (CPVC). The type of poly(vinyl chloride), and chlorinated poly(vinyl chloride) shape product may be categorized by type, grade, and class depending on resin composition: Types 01 and 02; Classes 0 and 1; Grades 0 and 1. The type, class and grade is further differentiated based on dimensional stability. The following test methods shall be performed: tensile stress at break; elongation at break; tensile modulus; dimensional stability; lengthwise chamber; flexural modulus; izod impact; and degree of fusion of extruded PVC and CPVC by solvent immersion.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
Significance and Use
1.1 This specification covers requirements and test methods for the material, dimensions, and workmanship, and the properties of extruded shapes of rods and bars made from poly(vinyl chloride) (PVC), and chlorinated poly(vinyl chloride) (CPVC).
1.2 The properties included in this specification are those required for the compositions covered. Use the classification system given in Section 4 to describe requirements necessary to identify particular characteristics important to specialized applications.
1.3 This specification allows for the use of regrind and recycled plastics as defined in Guide D7209 providing: products produced from regrind or recycled PVC material can be shown to meet the requirements of this standard with regard to material classification, physical performance, dimensions and workmanship; and the regrind or recycled plastics used have not been subjected to severe environments in post consumer applications (such as chemical service) which could adversely affect the end products performance when subjected to machining or critical applications or both.
1.4 The values are stated in inch-pound units and are regarded as the standard in all property and dimensional tables. For reference purposes, SI units are also included in Table 1 only.
1.5 The following safety hazards caveat pertains only to the test method portions section of this specification: 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.
