Significance and Use
Data obtained by these methods may be used to determine the transmitted shock cushioning characteristics of foam-in-place packaging materials. These data allow design of cushioning systems that can provide adequate and efficient use of foam for protection of goods during a distribution life-cycle.
These methods, in contrast to other methods that usually test only the cushioning foam, are designed to evaluate foam-in-place cushioning materials in a manner in which the foam-in-place packaging material is used. In particular, the method includes simultaneous use of a plastic film, the foam, and the box usually used in this method of packaging. See Fig. 1.
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 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 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.
