Slip-Test Mark IIIB: the first tribometer on the market to achieve Certification to ASTM F2508!  Click here for a spec sheet!  Slip-Test interview on Corporate Review

ASTM’s F13 Pedestrian Safety Committee and top biomechanical researchers worked 11 years in developing standard ASTM F2508. An F2508 Validation verifies whether a tribometer's readings can be reliably correlated to actual human slip events. Certification of a tribometer design to F2508 is an even more rigorous multi-step process, involving an Interlaboratory Study that documents the repeatability and reproducibility of tribometer measurements.  See the Mark IIIB Certification Report here!

Slip-Test is the sole manufacturer of research - proven Mark IIIB tribometers, totally re-engineered from the original designs of safety pioneer Dr. Robert Brungraber.
