ASTM D8366-21a

Standard Specification for Extruded and Compression Molded Shapes Made from Unfilled Poly(Vinylidene Fluoride) PVDF

SCOPE
1.1 This specification covers the requirements and test methods for the material, dimensions, workmanship, and the properties of extruded sheet, rod and tubular bar manufactured from unfilled PVDF.  
1.2 This specification covers the requirements and test methods for the material, dimensions, workmanship, and the properties of extruded and compression molded shapes manufactured from unfilled PVDF.  
1.3 The properties included in this specification are those required for shapes made from PVDF polymers. Requirements necessary to identify particular characteristics of the shape are included in Section 5.  
1.4 This specification allows for the use of up to 20 % process regrind and reprocessed plastic, total, and of uncontaminated quality.  
1.5 The values stated in English Units are to be regarded as the standard in all property and dimensional tables. For reference purposes, SI units are also included.  
1.6 The following safety hazards caveat pertains only to the test method or test methods described in 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.  
1.7 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
of the standard as published by ASTM is to be considered the official document.
