New footwear may initially have a lower slip resistance than that indicated by the test results. The slip-resistance of the footwear may change, moreover, in relation to the wear and tear of the sole. Compliance with the requirements does not guarantee the absence of slips in any conditions. ESD = ELECTROSTATIC DISCHARGE Footwear marked ESD differs from normal safety shoes that bear the antistatic mark (A) in that it has electrically dissipative properties, in other words the static electricity accumulated in the human body is continuously conducted to ground. The use of this footwear is regulated, as an extension of protection, by the EN ISO 20345:2011 standard. ESD shoes are distinguished by a specific yellow stamp and are necessary: When working with microchips When making sensitive electrical components When painting In the laboratory In the medical field When working in contact with flammable gases and liquids SLIP-RESISTANCE OF SOLE This characteristic is prescribed by the EN ISO 20345:2011 standard in accordance with the method set out in EN ISO 13287:2012 as per the following table: ADDITIONAL MARKINGS The symbols in the following table indicate supplementary characteristics that are re- quired for certain special applications of the footwear, which will be added to the safety categories: SYMBOL TEST CONDITIONS STANDARD REQUIREMENTS SRA Test surface: ceramic Lubricant: water and detergent ≥0,32 footwear on flat surface ≥0,28 footwear on surface with a slip angle of 7° SRB Test surface: steel Lubricant: glycerine 0,18 footwear on flat surface ≥0,13 footwear on surface with a slip angle of 7° SRC SRA + SRB Both the requirements indicated above SYMBOL FOOTWEAR CHARACTERISTICS Electrically insulating footwear A Antistatic footwear AN Ankle protection B Water vapour permeability of the upper C Conductive footwear CH Chemical resistance CI Insulation against cold CR Cut-resistant upper E Shock absorber heel FO Oil-resistant sole HI Insulation against heat HI 1 Insulation at high temperatures tested at 150ºC for 30 minutes HI 2 Insulation at high temperatures tested at 250ºC for 20 minutes HI 3 Insulation at high temperatures tested at 250ºC for 40 minutes HRO Heat-resistant sole I Electrically insulating footwear IPA Ankle protection against impacts IPS Shin protection against impacts IS High electrical resistance of the sole M Metatarsal protection P Puncture-resistant sole R Sturdiness of the toe (in the absence of a protective toecap) T Protective toecap tested for impacts of 200 J and a crushing force of 15 kN.
