Standard Test Methods for
Transmitted Shock Characteristics of Foam-in-Place
Cushioning Materials1

This standard is issued under the fixed designation D 4168; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of 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 These test methods determine the shock-absorbing characteristics of foam-in-place packaging materials.

1.2 Test Method A uses a free-fall package drop test apparatus.

1.3 Test Method B uses a shock-test apparatus.

1.4 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.
