For Complete Footwear
P. Puncture resistance: the footwear incorporates insoles (which may be metal or textile anti-puncture) with a puncture resistance of 1,100N force.
C. Conductive footwear: its electrical resistance is from 0 to 100 kilohms. It is designed to evaporate electrostatic charges.
A. Antistatic footwear: Although it is similar to label C, this label is intended for safety footwear designed to dissipate electrostatic charges between 100 and 1,000 kilohms.
HI. Heat resistance of the sole: insulation against heat of the sole of the footwear up to 150ºC.
CI. Cold resistance: provides insulation against cold of the sole of the footwear up to -17ºC.
E. Energy absorption in the heel area: this area of the safety shoe must be able to absorb a minimum of 20 J of energy.
M. Metatarsal protection: the footwear incorporates additional metatarsal safety.
AN. Ankle protection: the footwear incorporates added ankle protection.
CR. Cut Resistance: the shoe has a protection zone resistant to possible zones
WR. Waterproofing: the entire shoe must be waterproof.
IInstep Only
WRU. Resistance to water penetration and absorption: the upper of the shoe shows resistance to water inclusion and absorption.
OOnly On The Sole
HRO. resistance to contact heat: the sole can withstand contact heat with temperatures up to 300ºC.
FO. Resistance to hydrocarbons: the sole of the footwear is resistant to contact with hydrocarbons. This is a minimum requirement for safety footwear.
Another basic requirement is slip resistance, which is discussed in more detail below.
SSlip Resistance (basic Requirements)
The slip resistance criteria for safety, protective and work shoes are as follows:
Slip resistance on ceramic tile flooring with sodium lauryl sulphate (SRA marking).
Non-slip on steel floor with glycerine (SRB marking).
Slip resistance on ceramic tiles with sodium lauryl sulphate and on steel floor with glycerine (marked SRC).
