Scrape Adhesion Test
The stylus used for scrape adhesion is a 1.6 mm (0.0625 inch) drill
rod, bent to a 180° loop with 6.5 mm (0.256 inch) OD, hardened,
buffed and chrome plated. Supplied with the tester is a set of
twelve slotted weights with storage rack. In the adhesion test,
weights are applied in 0.5 kg increments to a maximum of 10 kg.
Mar Resistance Test
By moving a free edge of the test film against the needle under
a variable load expressed in grams, mar-resistance is determined
as the minimum load in grams required to cut through the film
to the substrate. In the mar (scratch resistance) test, weights can
be applied in increments from 10 grams to a maximum of 12 kg. |
