Since January 30, 2015, ENAC has granted Accreditation 1131 / LE2203 to the Slippery Laboratory according to criteria set out in the UNE-EN ISO / IEC 17025 Standard for conducting tests on:

Critical slip angle test of barefoot pavements for wet areas according to DIN 51097-1992 Ramp.

• The procedure described in this standard serves as an aptitude test to investigate and evaluate the slip resistance of the pavement on which people are expected to walk barefoot.
• Two persons shall determine the maximum angle of inclination of the ramp of the test apparatus, walking four times each on it and always starting from a horizontal position on the pavement under test.

The arithmetic mean of the eight measurements will be calculated. In the event that there are measurements whose difference is more than 2 ° with respect to the mean, the test will be repeated and the average will be calculated over 16 measurements.
