The technical characteristics and performance of a tile are just as important as its aesthetic, particularly in commercial environments with high footfall.
At Parkside we use Pendulum Test Values (PTV) to determine the slip resistance of our tiles.
All of our tiles are tested for slip resistance by our suppliers and then tested again, in house, by a member of our Technical team, giving you peace of mind when selecting your slip resistant tile.
The pendulum test consists of a swinging arm with a rubber foot, which is then allowed to fall and make contact with the tile being tested. The test replicates a person's heel strike, the point at which most slips occur. There are two different rubbers used in testing, one replicates the sole of footwear, the other is a softer rubber designed to provide values relating to a bare foot. Water is used as a contaminant in order to measure the slip resistance of tiles in both wet and dry environments and the results are then recorded. The tests are carried out in accordance with BS7976-2:2002 and UK Slip Resistance Group guidelines.
The higher the Pendulum Test Value the higher the level of slip resistance. Customer safety is our top priority when we test for slip resistance, which is why we have chosen to use pendulum testing as our measurement method.
There are many benefits to PTV testing:
Other types of testing
You may see 'R' values quoted elsewhere, which is the value given from ramp testing to record slip resistance of a tile. There are 2 tests methods used for ramp testing, one (DIN 51097) where the operator is barefoot and the contaminant is soapy water, and the other (DIN 51130) where the operator wears rubber soled boots and the contaminant is engine oil. It works by inclining a ramp covered with the flooring of choice and inclined a degree at a time until someone walking on the ramps slips. Based on the angle of slip, the rating is given for the tile. These standards are extensively used across Europe. However, there are several disadvantages to ramp testing;
What classifies a tile as slip resistant within Parkside?
During testing, the Pendulum machine will record results for each tile in wet and dry environments, simulating shod foot and barefoot conditions. The higher the recorded value, the higher the slip resistance. The following table represents the pendulum test values and how that translates to slip resistance.
|0 - 24||Low|
|25 - 35||Moderate|
While all tiles have some slip resistant properties and can be categorised into low, moderate and high slip resistance, at Parkside we only classify a tile as high slip resistant if it has achieved a PTV of 36+ in shodfoot wet conditions. This means that these tiles have low slip potential, to give you peace of mind when specifying.
A value of 36+ is regarded as a slip resistant tile and indicates a probability of one in a million of slip on a horizontal surface. However, the PTV may be affected by the installation and maintenance processes due to the following factors:
It is important that tiles are cleaned and maintained correctly to ensure that slip resistant values are maintained over time.
Floor tiles with high slip resistance (36+ PTV)
A selection of our floor tiles that have been tested and returned a 36+ PTV are shown below. These tests are based on initial stock and would require further testing prior to specification. Test certificates are available upon request.
