Slip Testing Services for Surfaces

At SlipDoctors we receive many queries about slip tests for surfaces. There are numerous reasons for these queries, but the most common question is ‘why organizations need slip testing for their surface SCOF / DCOF?’.

Why you require slip-resistant testing

Flooring manufacturers specifically need slip-resistant testing information for architects, designers and engineers who evaluate surfaces for new construction to comply with national ANSI standards.

At SlipDoctors, we can slip test a wide range of surfaces, including tiles, concrete, metal, vinyl and various other types of floors. As building trends evolve and new and unique materials are used for flooring, slip-coefficient testing is important to consider. All walking surfaces should be tested for DCOF or SCOF levels.

Do you need floor slip-resistance testing to determine traction levels?


We offer both in-house and field slip-resistance testing services for COF/DCOF ratings. Our knowledgeable and experienced Walkway Auditors can help test your flooring surfaces and help determine how to increase traction.

Pendulum Test

The pendulum test is essential for anyone who wants to reduce the risk of accidents as a result of slippery surfaces. The test uses an instrument known as a pendulum tester to measure the dynamic coefficient of friction. This is the friction existing between two objects when at least one of them is moving. The value of this measurement is used to determine the slip resistance of a surface.

The pendulum test complies with all relevant international standards, including:

- BS EN 16165:2021 Annex C
- BS EN 13036-4:2011
- BS 7976-1:2002+A1:2013
- BS EN 1097-8:2020
- BS 812-114:1989
- ASTM E303-93:2018
- AS/NZS 4586-2013
- AS/NZS 4663-2013

    How the pendulum test works

    The pendulum test is performed by swinging a prepared rubber slider across a surface using a mechanical foot. The slider imitates the heel of a real shoe or a barefoot. The foot slows down depending on the level of slip resistance as it makes controlled contact with the surface over a set distance. On the appropriate scale, the pendulum test value is measured.

    Results showing a value of 36+ are considered to have low slip potential, with moderate scores ranging between 25 and 35, and high slip potential scores ranging between 0 and 24.

    Equipment: Many providers are equipped with multiple testing machines including the BOT-3000E, British Pendulum, ASM 925, ASM 825 and more. Slip test equipment can be used to test almost any surface, except for carpets.

    Standards: Some of our standard slip tests include wet testing to ANSI A137.1 / A326.3 or (formerly ANSI) NFSI B101.1 / B101.3 / B101.4 - Barefoot test.
