Determine Your Unique Test Factor Number to Ensure Consistency in Your Wear Testing.
Instructions:
- Develop test plates for each coating you test.
- Run several wear tests on these test plates, determine the average fail number and make this your standard.
- To confirm or determine the Factor of your test paper, test the plates again with the different test paper.
- Example: If your Standard fail number is 300 and it is 250 with the new test paper, your Factor is 1.20 (i.e. 300 / 250).
Always divide your Standard number by the new number.
