ASM825A Operator Certification Course, Level 1

Learn to use the ASM825A tribometer for wet SCOF measurements

In this course you will learn:

1. Understand the physics of Coefficient of Friction (COF)

2. Understand how to calculate Static and Dynamic COF

3. How to prepare, calibrate, and conduct wet SCOF tests using the ASM 825A

4. How to use the ASM 825A following ANSI/NFSI B101.1 wet SCOF procedures

After each lecture section there is an open test of the material. A pass rate of 75% is required for successful completion of the course. Upon completion a digital "ASM Operators Certificate, Level 1" will be awarded.

NOTE: We recommend purchase of the B101.1 Wet Static Coefficient of Friction test standard. The course teaches how to use the B101.1 procedure with the ASM 825A to measure installed surfaces but does not include any of the walkway safety information or the procedure for measuring uninstalled surfaces.


Craig Stephenson, President, American Slip Meter - "This course is approved by American Slip Meter. We recommend it for anyone using an 825A. The videos teach you to properly prepare, calibrate, and test wet static coefficient of friction."
