Safety standard requirements EN-ISO 20345:2011

Standard safety classes

• SB = Basic requirements
• S1 = SB + A + E + FO
  SB + closed seat region, antistatic properties, shock-absorption in the heel region + hydrocarbons resistant sole
• S2 = S1 + WRU
  S1+ upper resistance for water absorption and penetration
• S3 = S2 + P
  S2 + puncture resistance, sole with cleats

Slip resistance

• SRA: slip resistance ceramics and deterging solution
• SRB: slip resistance on steel with glycerin
• SRC: SRA + SRB ceramics and detergent - steel and glycerin
