429 STANDARDS AND CERTI FICATIONS ELECTR I C ARC I EC 61 482-2 : 201 8 This is the standard specifying test methods for materials and protective clothing that must be resistant to heat and fire against arc flash hazards. The performance of the standard is divided into the following two classes: - Class 1 = Effective protection performance against a 4 kA electric arc - Class 2 = Effective protection performance against a 7 kA electric arc WELD I NG AND RELATED WORK PROCESSES EN I SO 1 1 61 1 : 201 5 This is the standard specifying the minimum basic safety requirements and test methods for protective clothing worn during welding and related work processes presenting comparable risks , including hoods, aprons, sleeves and gaiters which are designed to protect the body of the wearer including the head (hoods) and feet (gaiters). - Class X indicates the protection against welding procedures with slight (class 1) or strong (class 2) splatters and droplets formation. - Ax specifies which procedure (A1 or A2) is used to determine the flame spread. FLAME EN I SO 1 41 1 6 : 201 5 This standard specifies the performance requirements for materials, material assemblies and limited flame spread protective clothing in order to reduce the possibility of clothing burning, when in occasional and brief contact with small flames, thus posing a hazard itself. It also specifies additional clothing requirements, including design requirements, mechanical requirements, labelling and information provided by the manufacturer. (When protection against heat hazards is required in addition to protection against flames, this international standard is not appropriate). HEAT AND FLAME EN I SO 1 1 61 2 : 201 5 This standard specifies performance requirements for clothing made of flexible materials designed to protect the body of the wearer, with the exception of the hands, from heat and/or flame. . With regard to the protection of the head and feet, the only items of protective clothing falling within the scope of this standard are gaiters, hoods and boot covers. (Regarding hoods, no requirements are given for face shields and breathing equipment). - A indicates the procedure for determining the flame propagation (Procedure Ax: A1 o A2) - B indicates resistance to convective heat - B indicates resistance to radiant heat - D indicates resistance to molten aluminium splashes - D indicates resistance to molten iron splashes - F indicates resistance to contact heat Across many of the listed risks there are three levels of performance x: - Level 1 to indicate low risk exposure; - Level 2 to indicate medium risk exposure; - Level 3 to indicate high risk exposure; Ax Bx Cx Ex Fx Class X Ax
