ASTM D6263-23

Standard Specification for Extruded Rods and Bars Made From Rigid Poly(Vinyl Chloride) (PVC) and Chlorinated Poly(Vinyl Chloride) (CPVC)

ABSTRACT
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.
SCOPE
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 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 1: There is no known ISO equivalent to this standard.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
