Measuring the Static and Dynamic Coefficients of Friction of a surface requires use of a tribometer like the Johnson Forensic GS-1. The GS-1 can be used on most surfaces to measure wet and dry static and dynamic coefficients of friction. In this 4-hour Johnson-approved course you’ll be trained how to use the GS-1 to measure wet and dry static and dynamic coefficients of friction. The course explains the science of slip resistance, the physics of coefficient of friction (COF), and the difference between wet and dry static coefficients of friction (SCOF). Proper preparation and calibration of the GS-1 is essential to properly measuring SCOF and DCOF. The course uses in-person instruction to demonstrate how to prepare neolite and SBR sensor materials. The pretest calibration process is demonstrated. The B101.1, B101.3, and A326.3 procedure to measure dry and wet SCOF and DCOF is explained and demonstrated.
The course includes:
- Classroom instruction on the GS-1 preparation, calibration, and test processes
- Practical, hands-on use of the GS-1 using the B101.1, B101.3, and A326.3
- How to use the GS-1 to use scientific principles to measure the slip resistance of shoe treads
- Access to the 3-hour online course “Walkways: What You Need To Know To Design, Maintain, and Insure Cleaner, Safer Floors” (Regular Price $80)
- Written and practical test
- Johnson Forensic GS-1 Operators Certificate Level I and II
This course trains you to properly use the GS-1. Further study is required to assess slip resistance and provide walkway safety services.
