What is the standard for slip resistance?

ANSI A 137.1 is now (year 2014) a requirement of ANSI with “slip resistance” defined as testing at . 42 or better for a level interior floor finish expected to be walked upon when wet. This test is not recommended for outdoor areas or ramps.

What does R10 slip resistance mean?

R10 Anti Slip Rating – Options that possess R10 anti slip ratings will provide minor to moderate resistance to slipping, making them ideal for use in hallways, kitchens, and other living spaces including bathrooms.

What is acceptable DCOF?

This standard provides a test method, but also includes discussion about how the wet DCOF value of 0.42 is acceptable as a minimum value for surfaces that are expected to be walked on when wet with water. The standard can be downloaded from the Tile Council of North America.

How is slip resistance measured?

Slip resistance is measured in Coefficient of Friction (COF), which is equal to the ratio between the maximal frictional force that the sole of the shoe exerts and the force pushing the sole across the surface.

What is ASTM D2047?

ASTM D2047 is the basis of the testing of floor “waxes” (floor finishes) for slip resistance under laboratory conditions. It involves the James Machine with a leather friction pad measuring static friction, and specifies that all testing must be performed dry.

What is the difference between COF and DCOF?

COF (Coefficient of Friction) is a numeric value that represents the amount of friction between two objects. DCOF (Dynamic Coefficient of Friction) specifically tests the friction of an object that is already in motion (kinetic).

Is R10 OK for bathroom?

Often used to prevent slippage in domestic situations, the R10 tiles will be perfect for kitchens and bathrooms. In addition to bathrooms (where they should be used in combination with a bathmat) and kitchens, R10 tiles are also a good fit for living rooms and hallways, where occasional spills and wetness can occur.

What is the best slip rating?

P5
The classification methodology has also been changed, previously the 2004 version of AS 4586 used V to Z classifications. This has been superseded by the 2013 release with P0 to P5 classifications – P5 being the highest achievable level of slip resistance.

What should DCOF be for shower floor?

There is little agreement on what is suitable, but it is normally accepted to have an average Coefficient of Friction rating of . 6 per ASTM C1028 or DCOF minimum of 0.42 per ANSI A137. 1 for wet and dry surfaces.

What is ASTM C1028?

ASTM C1028 is a standard test method for determining the static coefficient of friction of ceramic tile and other like surfaces by the horizontal dynamometer pull-meter method. It is generally accepted that a coefficient of friction of 0.5 or above is relatively safe on a surface.

What is slip resistance R9?

R9 is the lowest rating for anti-slip tiles, meaning they are fine for domestic environments and, if they made of porcelain, some commercial environments where anti slip properties are not really required. DON’Ts: Ideally, R9 tiles should not be used outdoors or in wet environments.
