Description / Abstract:
This test method yields quantitative information regarding the
degree of blocking (unwanted adhesion) existing between layers of
plastic film. It is not intended to measure susceptibility to
blocking.
By this procedure, the film-to-film adhesion, expressed as a
blocking load in grams, will cause two layers of film with an area
of contact of 100 cm2 to separate. The test method is
limited to a maximum load of 200 g.
The values stated in SI units are to be regarded as standard.
The values given in parentheses are for information only.
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.
NOTE 1—This test method is similar to ISO 11502 Method B, but is
not technically equivalent.
