Grating anti-slip test results

Measurement of surface slipperiness

A laboratory slipperiness assessment was undertaken by the Health & Safety Laboratory (UK) in accordance with guidelines recommended by United Kingdom Slip Resistance Group (Issue 2,2000) and protocols outlined in BS 7976:2.

Measurements of the grating sample 'Slip Resistance Value' (SRV) were made using a calibrated Stanley Pendulum instrument. Measurements were taken in three directions to account for potential surface directionality.

Pendulum measurements were taken in 3 directions for accurate assessments:

Surface microroughness - slip risk classifications

An indication of slipperiness in water-contaminated conditions where obtained by measuring the surface roughness of our flooring materials.

Measuring the Rz parameter allows slipperiness to be predicted. Rz is a measure of total surface roughness, calculated as the mean of several peak-to-valley measurements.

Applicable for water-wet, low activity pedestrian areas. Data could not be generated due to the level of roughness exceeding the range of this instrument. This suggests the measurement would be at least 100 and therefore a low slip risk.

The test results presented relate only to the flooring samples under study at the time of testing.

The performance of installed materials may change significantly during their lifetime: slip resistance is critically dependent on the level and type of contamination, application of the surface treatment, wear, maintenance and effective cleaning subsequent to installation.
