GBP 57 INFORMATION RELATING TO PROTECTIVE WORKWEAR Standards: The standard EN ISO 13688 – (old EN 340) regulates the general requirements for protective clothing Ergonomics, ageing, sizes, identification and resistance to damage are part of this standard. In respect of certification, materials with OekoTex certificates must be used throughout, so as to avoid undesirable effects such as allergies, irritation or injuries. EN ISO 20471 EN 13034 type 6 High visibility clothing Clothing providing protection against liquid chemicals The international standard defines the requirements for protective clothing for Specifies the minimum requirements of re-usable personnel who perform work in environments that require heightened visibility. chemical protective overalls of textile materials and their use. This standard specifies the performance demands in respect of colour and These offer only restricted protection against the effects reflectivity, together with the minimum surface areas and the requirements of the of liquid aerosols, sprays and light spatter. materials down to the smallest size. The class designation (the number together with the symbol) denotes how well the product protects the wearer. EN 1149 Clothing with electrostatic characteristics The standard determines the requirements for materials and versions. EN ISO 11612 EN1149-1: Test procedure for surface resistance Protective clothing for protection against heat and flames EN1149-2: Test procedure for breakdown resistance Regulates clothing of flexible materials which protect the body of the wearer EN1149-3: Test procedure, measurement of the charge dissipation (except for hands) against heat and/or fire. It relates only to clothing, head coverings and protective gaiters. EN1149-4: Test procedure for the pieces of clothing The letters indicate the classes that it satisfies. EN1149-5: Performance requirements (materials/construction) The higher the number, the greater the guaranteed protection. EN 14116 Protective clothing for protection against heat and flames This standard specifies the requirements for prevention of flame propagation and EN IEC 61482-2 for the barrier characteristics of materials, combinations of materials Working on live components – protective clothing against and protective clothing. Brief contact with a small flame is not considered a the thermal hazards of an electric arc significant hazard. The standard describes procedures for testing materials for protective clothing Classification is performed in three classes (index 1 – 3). that are exposed to flames, heat, radiation and molten metal splashes from electrodes in the event of an electric arc explosion. In the open arc test (EN IEC 61482-1-1), all layers of the material are tested for their arc characteristic value (ATPV = Arc Thermal Performance Value). The ATPV indicates the total calorific value of the electric arc or the acting energy (cal/cm2) which is required to cause a second degree burn. EN ISO 11611 Thus, the test procedure simulates a real accident situation. Protective clothing for welding and associated processes In the box test (EN IEC 61482-1-2), a garment material is exposed to an The standard specifies test processes and performance standards for electric arc. This is generated by a short circuit of a large darting flame. protective clothing worn when performing welding and associated processes. The current required to cause second-degree burns is measured. The clothing protects the wearer against small metallic spatter, brief contact with flames, and radiated heat from the welding arc. This allows two classes to be defined: Class 1 = Test current 4 kA / 0.5 s The distinction is drawn between two classes: Class 2 = Test current 7 kA / 0.5 s Class 1 = Protection against less risky welding and situations The protective clothing is not electrically insulating protective clothing for with little spatter and a low degree of radiated heat. low-voltage work as specified by EN 50286. Complete personnel protection also Class 2 = Protection against more risky welding and situations requires suitable additional protective equipment, such as a safety helmet / visor, with a high degree of radiated heat. safety gloves, etc. EN 343 EN 342 Wind-proof and Certified protection waterproof clothing against cold EN 14404 Knee protectors for working in kneeling positions EN 61340 Protection of electronic components against electrostatic phenomena Protective workwear certified to this standard is suitable for the manufacture of products that are sensitive even to low voltages of 100 V or more. Persons wearing ESD workwear protect such products in manufacture against electrical discharges that damage components. Clothing that is not suitable for an ESD environment can generate static electrical charges due to friction, influences (magnetic fields, effects of fields) or separation of materials. 332
