Floor Safety Standards

Understanding Slip Resistance with DIN EN 16165:2023

At Biosaver, our mission is to help you create safer spaces without compromising the look of your floors. To ensure that, our anti-slip coatings are developed in line with DIN EN 16165:2023, the latest European slip resistance testing standard — giving you peace of mind backed by real science.

What is DIN EN 16165:2023?

DIN EN 16165:2023 is the European standard for evaluating slip resistance on floor surfaces. It replaces older standards like DIN 51097, DIN 51130, and BS 7976-2, combining multiple test methods under one harmonized framework.

This standard is divided into four annexes, each covering a different method of testing:

Annex Test Type Used For Replaces
Annex A Barefoot Ramp Test Wet barefoot zones like pools and bathrooms DIN 51097
Annex B Shod Ramp Test Wet or greasy areas with shoes: kitchens, clinics, etc. DIN 51130
Annex C Pendulum Test Dry and wet pedestrian zones (common in the UK) BS 7976-2
Annex D Tribometer Test Lab test for dynamic/static friction (used in EU & USA) New Method

Understanding the 3 Annexes

Anti-slip ratings under DIN EN 16165 are categorized into three annexes. Annex A is for barefoot areas, Annex B for shod (shoe-wearing) conditions, and Annex C uses the Pendulum Test for general pedestrian safety. Each annex is based on different test methods and previous DIN/BS standards.

Annex A – Barefoot Areas Ramp Test (formerly DIN 51097)
Class A
Low water exposure

Changing rooms and occasional splash areas.

Class B
Medium exposure

Showers, bathrooms, and standard wet rooms.

Class C
High exposure

Pool edges and spa ramps. BIOSAVER Class C

Annex B – Shod Areas Ramp Test (formerly DIN 51130)
R9–R10
Low slip resistance

For clean, dry indoor spaces like homes or offices.

R11–R12
High slip resistance

Kitchens, wet walkways, and workshops. BIOSAVER R12

R13
Extreme resistance

Industrial kitchens or heavily greased areas.

Annex C – Pendulum Test (formerly BS 7976-2)
PTV ≥ 36
Safe for wet use

Used in pedestrian zones, ramps, and public spaces.

PTV < 36
Not suitable

Fails to meet minimum safety for wet environments.

Why standards matter?

Most bathrooms and poolside areas might look clean and stylish — but they’re often not made to be safe when wet. Smooth ceramic tiles or stone surfaces can become extremely slippery, especially for barefoot children, seniors, or anyone with limited mobility.

That’s why having proper slip resistance isn’t just nice to have — it’s essential.
