OCCUPATIONAL

SLIP

CLASSIFICATION The International Standard specifies basic and additional (optional) requirements for occupational footwear that is not exposed to any mechanical risks (impact or compression).

WHAT’S THE RISK? Safety footwear should protect the wearer from slip hazards in the workplace, ensuring that critical elements such as sole design and compounds are optimal for use to protect the wearer from such hazards.

EN ISO 20347

EN ISO 13287

This European Standard specifies a method of test for the slip resistance of conventionally soled safety, protective and occupational footwear. It is not applicable to special purpose footwear containing spikes, metal studs or similar. The item of footwear to be tested is put on a surface, subjected to a given normal force and moved horizontally relative to the surface. The frictional force is measured and the dynamic coefficient of friction is calculated. If the outsole passes both the ceramic tile test (SRA) and the steel floor test (SRB) it is marked as SRC.
