WHAT IS EN ISO 13287? SLIP RESISTANCE DO YOU KNOW 24 This standard specifies a method for testing the slip resistance of conventionally soled SAFETY FOOTWEAR . It is not applicable to footwear with specific features such as studs or spikes or footwear that is designed for soft ground such as sand and sludge.

2. SRB

1. SRA SRA graded footwear is tested on a ceramic tile oor upon which a solution called sodium Lauryl sulphate (NaLS) is applied. This solution acts as a lubricant to gauge the slip resistance of the footwear in slippery conditions. The slip resistance is determined based on the frictional force of the itemof footwear i.e. its ability to resist slipping over the surface. The results are expressed as the dynamic coe cient of friction, a measure of resistance to slip accidents. SRA footwear is tested on ceramic oors only.

SRB graded footwear follows a similar test method as the SRA test described abovel but the test is performed on a steel oor with glycerol.

3. SRC SRC graded footwear is the marking given to an itemof footwear if the outsole passes both the ceramic tile test (SRA) and the steel oor test (SRB).
