How to interpret Pendulum Test results

Here at Slip Safety Services, we carry out a thorough on-site assessment that incorporates the industry recognised pendulum testing method, as used by Health and Safety Executive (HSE) & UK Slip Resistance Group (UKSRG). Through these effective testing methods, we are able to produce a comprehensive measurable report to outline areas of concern and recommendations of services and solutions to improve slip safety within your business.

The pendulum test works by replicating a person’s heel striking a floor and quantifies the amount of friction produced. It gives you a Pendulum Test Value, which equates to a category of slip potential:

PTV        Slip potential
0-24              High
25-35         Moderate
36+                Low

The PTV also equates to an accident risk exposure:
PTV    Risk
19          1 in 2
24          1 in 20
27          1 in 200
29          1 in 10,000
34          1 in 100,000
36          1 in 1,000,000










The HSE says that floors should achieve a PTV of 36+ in their intended end use. Critical to this therefore is understanding which of your floors are foreseeably wet and therefore need to achieve this number in both wet and dry conditions.
