ASTM D4819-13

Standard Specification for Flexible Cellular Materials Made From Polyolefin Plastics

ABSTRACT
This specification applies to flexible closed-cell materials made from polyolefin plastics and blends of polyolefin plastics. Two types of flexible, closed-cell polyolefin foams are covered: type I - closed cell foams made with polyolefin plastics and either chemically or radiation crosslinked, and type II - closed cell foams made with polyolefin plastics that are non-crosslinked. Cellular polyolefin foams furnished under this specification shall be manufactured from any resin or blend of resins that are members of the polyolefin family together with added compounding materials. Unless otherwise specified, the color of cellular polyolefin foams shall be natural.
SCOPE
1.1 This specification applies to flexible closed-cell materials made from polyolefin plastics and blends of polyolefin plastics as defined in Section 3.  
1.2 Extruded or molded shapes too small to permit the cutting of standard test specimens are difficult to classify or test by standard test methods and will usually require special testing procedures or the use of standard test sheets.  
1.3 In case of conflict between the provisions of this specification and those of detailed specifications for a particular product, the latter shall take precedence. These detailed specifications for the flexible closed-cell polyolefin plastic foams shall state the particular test or tests desired.  
1.4 In cases involving referee decisions, SI units shall be used.  
1.5 This specification does not contain test procedures or values for all the suffix letters listed in Table 1 and Table 2. Where the procedure is not described in this specification or special limits are desired, or both, the test procedures and values must be arranged between the purchaser and the supplier.
1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. Note 1—There is no known ISO equivalent to this standard.

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.
