VOSI SLIP & FALL STANDARD V41.23Y-98
FOR
SLIP RESISTANT FOOTWEAR, IN THE FIELD AND LABORATORY, AS MEASURED BY A DRAG TYPE FRICTION TESTER

1. SCOPE

1.1 This standard covers the static coefficient of friction requirements for pedestrian and worker's footwear in order to be called "Slip Resistant Footwear" under both dry and wet (water) conditions.

2. REFERENCED DOCUMENTS

2.1 VOSI V41.21, "Universal Specification/Test Method for Slip Resistant Walkways, in the Field & Laboratory, as Measured by a Drag Type Friction Tester".

2.2 VOSI V41.22, "Universal Specification / Test Method For Slip Resistant Footwear, in the Field & Laboratory, as Measured by a Drag Type Friction Tester".

2.3 Static COF Test Methods: ASTM F 609 (HPS), F 489 (James Machine), F 1678 (Brungraber Mark I).

2.4 Kinetic COF (KCOF) Test Methods: ASTM F 1677 (Brungraber Mark II), F 1679 (English XL)

2.5 CEN/T161 N279 European Standards Organization (18 countries) on footwear (KCOF).

3. TERMINOLOGY

3.1 All uniform definitions of terms, that affect public safety, are stated in 2.1 and 2.2.

4. SIGNIFICANCE & USE

4.1 This STANDARD references universal specification / test methods for measuring SCOF (and DCOF) of footwear materials in both the laboratory and field. Manufacturers of these materials, who use the various conflicting ASTM and ANSI test methods for measuring the SCOF of footwear products, may continue to use their test methods in addition to 2.1 and 2.2. These methods correlate to slip / fall accident rate (ref. 12 of 2.2 & 2.2)

4.2 Forensic engineers, in order to be credible expert witnesses in slip/fall cases, should use 2.1 and 2.2.

4.3 The public's safety requires that uniform specification / test methods be used when measuring the SCOF of walkway and footwear surfaces in both the field and laboratory.

5. KEYWORDS

5.1 Slip Resistant Walkways, Slip Resistant Footwear, Static Coefficient of Friction (SCOF), Dynamic Coefficient of Friction (DCOF used over seas)

This STANDARD is under the jurisdiction of Voices of Safety International (VOSI) committee V41.20 on "Pedestrian Slip Resistance Requirements for Walkways & Footwear".
