Standard Specification for
Flexible Cellular Materials Made From Polyolefin Plastics1

This standard is issued under the fixed designation D 4819; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. 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 is 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 should 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 similar or equivalent ISO standard.
