Two razor cuts are scored at a predefined distance about the length of the card centre line. The card is clamped to the test plate on the sliding bed by two rebated bars, locked into position by thumb-screws. A small section of the centre laminate is lifted away from the card and fixed in the upper vice grip. The crosshead of the test machine is driven upwards and the test plate, which can move freely in a horizontal plane, maintains an angle of peel of 90o during the peeling operation.

180° Credit Card Peel Jig
To perform 180° peel tests, Lloyd Instruments has designed a second jig. This fixture comprises a vice action grip fitted to the lower anchor pin and an upper thin plate fitted with a bar and two thumbs screws for clamping the peeled laminate into place.

The razor cuts are scored about the centre line along the length of the card and a section of this laminate is manually lifted. This peeled laminate section is locked against the opposite face of the backing plate using the clamp bar. The card is then swung into a parallel position to the packing plate in the vice action grip.

The backing plate, fitted to the loadcell on the machine's moving crosshead, is driven up by the test machine to perform the 180° peel test on the sample.

Applicable Standards
ISO/IEC 7810 - Identification cards - Physical Characteristics. This standard sets out a range of physical characteristics including the mechanical robustness of the card.
ISO/IEC 10373 - Identification cards - Test Methods. This standard deals with the test methods employed to test credit cards. Flexural tests are applied along both horizontal and vertical axis. Cards are also twisted to see if damage occurs to the laminate.
