What does PTV stand for?

PTV stands for Pendulum Test Value. The Pendulum test is the HSE’s preferred method of testing to assess the slip resistance of a surface. Testing is carried out in both wet and dry conditions.  The minimum PTV for low slip potential is 36. Our range of antislip decking comfortably exceeds the minimum scoring between 61 and 81 dependant on whether it is a wet or dry condition.
