ASTM F904-16

1.1This test method covers a procedure for comparing the bond strength or ply adhesion of similar laminates made from flexible materials such as cellulose, paper, plastic film, and foil. This includes laminates made by various processes: adhesive laminates, extrusion coatings, extrusion laminates, and coextrusion.

1.2Because of the impact of the bending force, direct comparisons between different materials or even between the same materials of different thickness cannot be made.

1.3The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.

1.4This standard does not purport to address all of the safety problems, 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. Specific precautionary statements are given in 7.1.1.
