Click link to view NFSI B101.2 Roster

Scope: This standard covers the change in dynamic coefficient of friction (DCOF) resulting from various chemical or physical walkway surface treatments on ceramic tile or other hard floor surfaces under wet conditions. This standard can be used in the laboratory or in the field.

Purpose: This standard should be used for the purpose of judging the relative impact of a particular chemical or physical walkway surface treatment on a specific hard floor substrate with regards to the wet DCOF of that surface. This is just one factor in determining the safety of the floor from a slip resistance perspective.

Application: This standard applies to various chemical or physical walkway surface treatments on appropriate hard floor surfaces under wet conditions. Its application is limited by the technology used to measure wet DCOF, and does not apply to all walkway surfaces (detailed further in the standard).

Section 1: Scope/Purpose/Application/Exceptions

1.1 Scope

This test method specifies the procedure and devices for both laboratory and field testing to measure the wet Dynamic Coefficient of Friction (DCOF) for hard surfaces that are intended to be used under wet barefoot conditions where individuals stand, step, bathe, shuffle or walk including all types of indoor and outdoor improved surfaces in public or private areas.

1.2 Purpose

This test method provides a measurement procedure setting forth wet DCOF ranges in the wet barefoot condition by individuals who stand, step, bathe, shuffle, or walk, which facilitate remediation of walkway surfaces when warranted.

1.3 Application

The test measurement procedure specified in this standard for surfaces intended to be used wet in a walking barefoot condition shall be conducted using the Dynamic Coefficient of Friction (DCOF) method only.

This test method applies to all types of commercial and residential hard surfaces intended to be used wet in the barefoot condition in a standing posture to any extent, where individuals stand, step, bathe, shuffle or walk including all types of indoor and outdoor improved surfaces in public or private areas. This test method includes, but is not limited to the following locations:

  • Bathroom/locker room shower surfaces/tiles/pans/enclosures.
  • Bathroom/tub/hot tub/jacuzzi/spa/sauna/steam room surfaces/enclosures.
  • Physical therapy areas and apparatus involving water, such as but not limited to whirlpool/hydrotherapy baths or water massage.
  • Bathroom/locker room floor tiles and floor surfaces.
  • Commercial facilities, residential homes, multi-dwelling units, hotels, and water parks.
  • Splash parks and water spray/fountain areas intended for human use.
  • Water slide standing entry launch pools and user access areas.
  • Private or public pool decks, patios, diving boards, and pool entry stairs/ramps/ladders.
  • Cruise ship swimming pool decks, entries, copings and stairs.
  • Marine vessel standing surfaces/decks intended to be used in wet barefoot conditions.
  • Public/private/commercial/residential/lake, pond, beach and waterfront piers and docks.
  • Normally submerged surfaces of wading pools, pool steps, skimmer gutters and wave pools that are able to be tested with an approved tribometer.
  • Private or public saunas, spas, and steam rooms.
  • Private or public recreation center shower rooms.
  • Swimming pool, spa, and sauna decks.

This test method does not apply to the following:

  • Unimproved land, natural walkways, natural ponds, rivers, grass, beach, and the like.
  • Water slide chutes.
  • Personal water rafts.
  • Inflatable water plays structures and toys.
  • Surfboards, waveboards, water skis, and the like.
  • Marine vessel/cruise ship surfaces/decks that are not intended to be used under wet barefoot conditions.
  • Personal watercraft seated foot placement areas.
  • Surfaces not intended to be used under wet barefoot conditions.
  • Soft surfaces such as fibrous materials (carpeting, carpet matting, etc.).

This test method includes all types of hard surfaces and materials used in the environments listed above upon which persons are intended to stand, step, bath, shuffle, or walk, including but not limited to: hard-surface materials such as a bathtub or shower enclosures, ceramic/porcelain tile, brushed/polished/painted/coated/finished concrete, textured/polished stone, acrylic, vinyl tile, wood, coated/painted metal, or synthetic laminates; impact absorbent materials such as foam-based/rubber-based tiles and sheets and coatings; composite surface materials; and such materials with coatings, polishes, appliques or other traction-enhancing treatment(s) are applied.

Note: This test method does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. No express or implied representation or warranty is made regarding the accuracy or significance of any test results in terms of preventing slips or falls in all cases for all people with all types of water-based contaminants. No surface material is completely slip-proof under all wet barefoot conditions with all types of contaminants. Judgment is required on a case-by-case basis to determine the intended use of the surface. 

1.4  Exceptions

This test method is not intended for dry surface testing and does not propose to be an accurate measurement method for determining dry surface traction. Dry surface test data should not be compared to wet surface data. No inferences should be implied or concluded regarding dry vs. wet COF test results from this test method.

This test method does not address wet surface testing with ordinary footwear, which is addressed in NFSI B101.3 (most current version). Scientific testing has shown that the traction provided by a wet surface may be higher for barefoot skin of all ages than for ordinary footwear when tested in the same manner, due to the pliability and characteristics of human tissue. This standard prescribes a test method that will ensure reasonably safe use of a wet surface specifically when barefoot.  As such, the performance values in this standard do not apply to ordinary footwear use. For surfaces intended to be used with both bare feet and ordinary footwear, compliance with slip resistance standards for footwear use will also be required. Use the appropriate standard for the incident being investigated. It is recommended to test both the SCOF and DCOF of the subject surface.

This standard does not address the wet barefoot use of ambulation aids, such as canes, crutches, walkers, rollators, prosthetics, or similar walking assisting devices.

NFSI B101.14 Forensic Standard for Slip and Fall Analysis using Tribometers

Scope: This standard will provide the technical procedures for forensic walkway evaluations including measuring the coefficient of friction (tribometry) of hard-walkway surfaces. This will apply to both public and private facilities as well as uninstalled and installed flooring and other walkways to determine the root cause of a slip and fall by a forensic expert.

Purpose: The purpose of this standard is to provide specific methods and procedures for the performance of a forensic analysis of a walkway in connection with a slip and fall claim and to ensure that sound scientific principles are being applied which will be accepted and validated through the rigors of litigation. At the same time the courts are provided a method which allows them to reduce or eliminate possible junk science in this forensic category and meet the stringent requirements set forth via a Daubert challenge.

Application: This standard will set forth multiple requirements in the process of a forensic evaluation of walkways to determine whether a slip and fall event was the result of an insufficient level of slip resistance (COF). It will serve as a defensible foundation from which a forensic expert can rely on existing walkway safety standards along with a physics (science) based approach to tribometry.
