1 Subject Content and Application Scope

This standard specifies the test device, specimen preparation, procedure and result expression of 180° peel test of flexible-bonded-to-rigid test specimen.
This standard specifies a 180° peel test for the determination, under specified conditions, of the peel resistance of a bonded assembly of two adherends where one adherend is flexible and the other is rigid.

GB 2918 Plastics - Standard Atmospheres for Conditioning and Testing

3 Principle

A bonded assembly of two adherends is prepared using the adhesive. The adherends are then pulled apart at a specified rate, starting at the open end of the bond, in such a way that separation occurs progressively along the length of the bonded adherends. The force is applied substantially parallel to the plane of the bond, through the separated part of the flexible adherend.
