Scope

i-COFTEK 3500 Friction & Peel Tester is designed to determine static and kinetic coefficient of friction tests of plastic films, sheets, foils, paper, paper board, PP woven bags, fabric style, and metal-material belts for communication cable, conveyor belts and textiles, as well as peel strength test of adhesive laminated products, medical adhesive bandages, release paper and protective films, etc.

Friction & Peel Tester for Thin Film

Test Procedures

A: Prepare test specimens according to specific standards. Based on ISO8295-1986, 2 specimens measuring 200mm×80mm are required for each test. In accordance with ASTM D1894, the size of the test specimen that is to be attached to the plane should be 250mm×130mm and the specimen that is to be attached to the sled should be a 120mm square (if the material of specimen is rigid, it should be a 63.5mm square). If the specimen is greater in thickness or rigidity, please cut a specimen with the same size as that of lower surface of sled. Generally the long dimension should be parallel to its machine direction. The specimen surface should be flat and should be free of dust, finger prints or any foreign matters which may change the surface characteristics.

B: Mount the test specimen. The connection of load cell and sled should conform to specific standards. In accordance with ISO 8295-1986, load cell is connected to sled via spring and steel wire. If slip occurs, please remove the spring holder and install it back in opposite direction. Connect the load cell and sled via steel wire directly. In accordance with ASTM D1894, the load cell could be directly connected with the sled via nylon filament.

C: Set up test parameters, specimen parameters and then start the test.

D: Record the test data and view the test curve. If the test curve is not satisfactory, the test should be abandoned and new test with another specimen should be started.
