IMPORTANCE OF SLIP RESISTANCE TESTS

More than 10% of injury accidents are caused by a slide. All sectors of activity and all trades are concerned. But some of them are more vulnerable, like the food industry and mechanical workshops, in environments where people has to walk on oily or smooth floors.

The wear of slip resistant safety footwear is therefore a fundamental Personal Protective Equipment. One of the mains concerns of MTS is to equip workers with comfortable shoes appropriated to the risks associated with their job.

How is measured today the slip resistance of a safety shoe?

The EN 13287 standard defines the specifications of footwear slip resistance and the test method. The safety footwear slip resistance is now a fundamental requirement of the standard EN ISO 20345:2011.

This standard measures the coefficient of friction of shoes when they slide in different positions (flat and on heel), on defined surfaces (ceramics and steel), and in presence of a pollutant (detergent, glycerin).

3 sizes are tested by sole pattern: the smallest, the average and the biggest.

The standard specifies 3 classes of slip resistance:

1. SRA : Slip resistance on Ceramic tiles covered with a Sodium Lauryl Sulfate (e.g. water + care product as a result of cleaning the floor)

The coefficient of friction must be:

  • Superior or equal to 0.28: during the sliding test on the heel moving forward
  • Superior or equal to 0.32: when testing the shoe in flat position sliding forward.

2. SRB : Slip resistance on a Steel floor (smooth indutrial type floor) covered with Glycerol (greasy product)

The coefficient of friction must be:

  • Superior of equal to 0.13: during the sliding test on the heel moving forward
  • Superior of equal to 0.18: when testing the shoe in flat position sliding forward.

3. SRC : Coefficient of friction satisfying the conditions of both classes SRA and SRB.

All the models of MTS brand safety footwear meet the optimal slip resistance SRC.

Furthermore, MTS shoes always get superior performance test results compared to the values required by the European standard. Depending on the design of the sole, this can even goes up to 70% of additional resistance!

These tests are carried out by the CTC (Centre Technique Cuir Chaussure Maroquinerie), located in Lyon in France, notified body, identified under the number 0075, published in the Official Journal. The CTC is actually studying new test resistance improvements, to make them ever more performant.
