The UK’s independent authority on slip resistance

UK Slip Resistance Group Guidelines – Issue 6

The UK Slip Resistance Group compiles, publishes and distributes authoritative guidance on how to reliably test the slip resistance of flooring materials.

The Assessment of Floor Slip Resistance
The UK Slip Resistance Group Guidelines
Issue 6 – 2024

Like all previous versions, version 6 remains as a guideline rather than a British Standard. Nonetheless, it is a comprehensive revision of version 5. Its purpose is to provide a consensus view of the UK Slip Resistance Group in how to undertake slip resistance and roughness measurements correctly, with increased clarity,  as well as to understand the meaning and limitations of test results.

There are many new sections and a number of modifications to testing methodology together with more prescriptive instructions, wherever possible. Some key features of version 6 include an important new section on interpreting test results, as well as consideration of a key new British/European standard for the measurement of slip resistance. Diagrams and photos have been used extensively to assist the user.

Version 6 supersedes all previous versions.
