Lloyd Instruments TG4977 Credit Card Peel Jig
90° Credit Card Peel Jig
The fixture comprises a mechanical self-adjusting sliding bed and an
upper vice action grip for clamping the peeled card laminate.
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.
