Slip Testing Standards
ANSI Testing (A137.1 / A326.3) American National Standard Test Method for Measuring Dynamic Coefficient of Friction of Hard Surface Flooring Materials.
Scope is standard describes the test method for measuring dynamic coefficient of friction (DCOF) of hard surface Flooring materials. is method can be used in the laboratory or in the field.
Dynamic Coefficient of Friction (DCOF): Sometimes called kinetic coefficient of friction. This is the ratio of the force necessary to keep a surface already in motion sliding over another divided by the weight (or normal force) of an object. This ratio is a materials property of the two surfaces* . DCOF is usually less than SCOF for the same materials. Contaminants such as dirt, water, soap, oil, or grease can change this value. * The laboratory values determined by this test method reflect the dynamic friction between the test foot using SBR rubber and the hard surface flooring being tested under specific controlled conditions. No claim of correlation to actual footwear or human ambulation is made.
Unless otherwise specified, hard surface flooring materials suitable for level 1 interior spaces expected to be walked upon when wet with water shall have a wet DCOF of 0.42 or greater when tested using SBR sensor material and SLS solution as per this standard.
The AcuTest, also known as ANSI A137.1 and newer more comprehensive of version ANSI A326.3 are a test method which references using the BOT-3000E, or like tribometer. While there are other DCOF meters available on the market, the TCNA (Tile Council of Noth America) has maintained their position not yet including other devices.
A326.3 and NFSI B101.1 both offer Dry Testing options. Please contact us for options regarding dry testing.
