ST60 Floating Roller Peel Test DIN 53 289/ASTM D 3167

This jig is used to test the peel strength of laminated samples where the backing sheet is rigid and the facing sheet is flexible. It complies with both the DIN and ASTM standards. It is an alternative to the climbing drum jig ST59 for testing laminates. The peel angle is greater than 90 degrees.

Samples as defined by the DIN and ASTM standards are near enough identical. The ASTM sample is 10″ long with a 2″ extension of the flexible layer, sample width is 0.5″ cut from a prepared sample of 3″ width.

The jig mounts on the upper crosshead of the machine with the sample laying on top of the rollers. The flexible sheet is facing downwards and the extended end is peeled back and bent down between the two rollers to be gripped by a suitable vice attached to the lower crosshead of the machine. As the test proceeds the flexible layer peels off the backing sheet which moves across the rollers to the right.

This fixture also complies with BS EN 2243 1991.
