The i-coftek 3300 coefficient of friction tester measures static and dynamic friction for various materials including plastics, rubber, and metals. It requires specific specimen sizes based on established standards like ISO8295-1986 and ASTM D1894 for accurate testing. The device also allows for testing the smoothness of daily chemical products, and prompts the operator to discard unsatisfactory tests and retry with new specimens.

i-COFTEK 3300 Coefficient of Friction Tester--Film Test
Scope
i-COFTEK 3300 Coefficient of Friction Tester is designed to determine static and dynamic coefficient of friction tests of
plastic films, sheets, rubber, paper, paper board, PP woven bags, fabric style, and metal-material belts for communication
cable, conveyor belts, wood, coatings, brake pads, windshield wipers, shoe materials and tyres, etc. Additionally the
instrument could be used to test the smoothness of cosmetics, eye drops and other daily chemical products.
Test Procedures
A: Prepare test specimens according to specific standards. Based on ISO8295-1986, 2 specimens measuring 200 mm×80
mm 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 250 mm×130 mm and the specimen that is to be attached to the sled should be a 120 mm square (if the
material of specimen is rigid, it should be a 63.5 mm square). 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.
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.
