The primary objective of this standard is to determine the or separation force required to pull apart bonded layers. This is essential for ensuring that laminated films do not delaminate during handling, storage, or use, which is vital for the integrity of products like medical packaging, food wraps, and protective coatings.

This method was used for materials where a clean separation of the individual layers is possible, such as with films processed from rolls. The specimen for Method A has a length of 200 mm. The width varies depending on the material: composite sheets are tested with a width of 50 mm ± 1 mm, while multi-layer plastic films require a width of 15 mm ± 1 mm. This method forms the basis for modern replacement standards. : Assisting engineers at testing facilities like imat-uve

Specimens must be conditioned in a standard atmosphere as defined in DIN 50014 (Standard atmosphere 23/50, i.e., 23°C ± 2°C and 50% ± 5% relative humidity) for at least 24 hours prior to testing. Testing Methodologies: Method A vs
