Floor Pendulum Slip Testing

Floor Pendulum Slip Testing

Recognised by the Health and Safety Executive the pendulum slip testing (BS EN 16165: 2021)  is recognised as a reliable and robust floor test. The test provides accurate analysis on the slip potential of all types of flooring. This slip testing can be used to portray barefoot and/or shod foot (shoes) and is completed in both wet and dry conditions.

The testing is based on a swinging, imitation heel sweeping over a set area of flooring in a controlled manner. The slipperiness of the flooring has a direct and measurable effect on the pendulum test value (PTV) given.

A total of 15 swings is conducted in three directions (0 degrees, 45 degrees and 90 degrees) and the average provides an overall PTV.

Once the average PTV is obtained the number is then assessed against the following scale to indicate the floors slip potential:

24 and below  – High Potential for Slip

25 – 35 – Moderate Potential for Slip

36+ – Low Potential for Slip

We’re able to accommodate and carry out testing in a range of locations and situations. If you have a bath, shower tray or floor we can bring along the fully mobile pendulum apparatus to carry out the slip test.


Sample Pendulum Tile Testing

For new projects, our in-house laboratory allows us to conduct testing of floor samples for a small fee. This can provide piece of mind and ensure all new floors meet HSE regulations once laid. This ultimately may save time and money in resolving slip issues once the floor is laid.

British Standard Pendulum Slip Testing (BS EN 16165: 2021)- requires one tile sample (minimum 200mm x 200mm). Tiles are tested in three directions.

European Testing – CE Marking – BS EN 14231 is testing for natural stone  – this testing requires 6 x samples of 200mm x 200mm tiles. This is testing in two directions (0 degrees and 180 degrees).

This offers full results before the tile is specified, providing you peace of mind the tile will be fit for purpose.

Please note: All our slip tests are undertaken using a calibrated skid tester (test in accordance with BS EN 16165 2021 and ‘The UKSRG (UK Slip Resistance Group)’ (issue 6, 2024). The HSE has adopted this as its standard test method for assessing floor slipperiness in both dry and water contaminated conditions.  All staff are fully trained in the use of the pendulums and all pendulums are calibrated in line with BS EN 1097-2020 BS EN 13036:part 4 2011, BS EN16165 & ASTM E303-93. Certificates of calibration will be provided on request.
