VOSI SLIP & FALL STANDARD V41.23X-98
SLIP RESISTANT WALKWAYS, IN THE FIELD AND LABORATORY, AS MEASURED BY A DRAG TYPE
1.1 This standard covers the static and dynamic coefficient of
friction requirements for walkway surfaces in order to be called "Slip
Resistant Walkways" 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
2.2 VOSI V41.22, "Universal Specification / Test Method For Slip
Resistant Footwear, in the Field & Laboratory, as Measured by a Drag Type
2.3 SCOF - Substrates: ASTM C 1028 (C21 / Ceramic Tile / Neolite), D 2394
(D 7 / Wood / Leather).
2.4 SCOF - Coatings: ASTM D 2047 (D 21 / Polish / Leather), D 4518 (D 1 /
Paint / Neoprene). DCOF, D 5859 (D1 Paint / Paint / Leather).
2.5 ISOTC189 International Standard for Ceramic Tiles.
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 the SCOF (and DCOF) of footwear and walkway materials and
coatings in both the laboratory and field. Manufacturers of these materials,
who use the various conflicting ASTM, ANSI and ISO test methods for measuring
the SCOF of flooring and footwear products, may continue to use their test
methods in addition to 2.1 and 2.2. These methods correlate with slip / fall
accident rate (Ref 12 of 2.1 & 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.
5.1 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".
