Coefficent of Friction Test Results
This report presents the results of coefficient of friction test conducted on samples of steel coated with Nye-Kote™, Nye-Tef™, Nye-Carb™, Kanigen® and Industrial Hard Chrome. The testing data analysis was complated on January 28, 2008.
SUMMARY OF RESULTS:
Sample Identification:
The samples were identified by thier coating indication; Steel, Nye-Kote™, Nye-Tef™, Nye-Carb™, Kanigen®, Hard Chrome.
Test Method:
The samples were allowed to condition at standard laboratory conditions of 72 +/- 4F and 50% +/-5% relative huimidity for at least 40 hours prior to testing. Testing was done with according to ASTM D1894. Standards used are detailed below.
