716 | SRA SRB SRC SR EN ISO 13287 EN ISO 20345 AP EN ISO 20345 LG >10mm >90° - <120° >1.5mm >35mm 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. In accordance with testing criteria of ISO 20344:2021, 5.21, the mean value of the test result shall not exceed 10 kN and no single value shall exceed 15 kN. The marking of this standard is AP. Within the European standard of EN ISO 20345:2021, the ankle area must be protected on the outer side of the footwear. The shape must be tested in accordance to EN ISO 20344:2021, 5.21, and at least the circular sizes of the below dimensions. Within the European standard of EN ISO 20345:2021 the cleat height in the waist area. When measured according to ISO 20344:2021, the outsole shall have a height of at least 1.5mm in the waist area. The outsole shall have an inclined breast heel. Distance shall be at least 35mm, angle ‘a’ shall be between 90° and 120° and dimension ‘b’ shall be at least 10mm. SLIPPERY SURFACES 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. ANKLE PROTECTION LADDER GRIP OUTSOLE WHAT’S THE RISK? Safety footwear can be subject to high impact and therefore can cause the wearer injury at the ankle bone. WHAT’S THE RISK? Footwear that includes a certified ladder grip outsole increases the safety when using ladders and climbing apparatus.
