LAHTI PRO PROLINE MEGA TRYTON VULCAN Technical informations PAGE WWW.PROFIX.COM.PL 197 LIST OF STANDARDS EN ISO 11611 – Protective clothing for use in welding and allied processes. This standard specifies minimum basic safety requirements and test methods for protective clothing including hoods, aprons, sleeves and gaiters that are designed to protect the wearer’s body including head (hoods) and feet (gaiters) and that are to be worn during welding and allied processes with comparable risks. This type of clothing is intended to protect the wearer against spatter, short contact time with flame, radiant heat from the arc used in welding and allied processes, and minimises the possibility of electrical shock by short-term, accidental contact with live electrical conductors at voltages up to approximately 100 V in normal conditions of welding. LIST OF STANDARDS EN ISO 11612 Protective clothing – Clothing to protect against heat and flame – Minimum per - formance requirements. This standard specifies performance requirements for protective garments made from flexible materials, which are designed to protect the wearer’s body, except the hands, from heat and/or flame. The performance requirements set out in this International Standard are applicable to protective garments which could be worn for a wide range of end uses, where there is a need for clothing with limited flame spread properties and where the user can be exposed to radiant or convective, or contact heat or to molten metal splashes. ANTISTATIC CLOTHING Being class 2 Personal Protective Equipment, antistatic clothing has to be certified in EC type test for conformity with Directive 89/686/EEC. LIST OF STANDARDS EN 1149-5 Protective clothing – Electrostatic properties – Part 5: Material performance and design requirements. This standard specifies material and design requirements for electrostatic dissipative protective clothing, including hoods and caps, used as part of a total earthed system, to avoid incendiary discharges, where the minimum ignition energy of an explosive atmosphere is not less than 0.016 mJ. PURPOSE Antistatic protection clothing is required in hazardous zones (such as in chemical, mining, or oil industry, transport of dangerous substances, gasworks, power plants) and outside hazardous zones (such as the production of electronics to prevent static damage). MATERIAL REQUIREMENTS Antistatic protective clothing is made of materials that can dissipate and drain off static charge, which prevents incendiary discharges. DESIGN REQUIREMENTS Antistatic clothing should meet specific design requirements to prevent static discharge: • Clothing should cover the whole body of the wearer, also in motion and a bent position. • Clothing should fit well and not restrain movement also when buttoned up during use. • If clothing is made of a set of materials, the antistatic material should be the outer layer. • Fasteners made of conductive material such as zip fasteners, buttons, or snap fasteners may be used as long as they are covered with antistatic material. • In materials that contain parallel or interlaced conductive yarn, the distance between conductive threads running in the same direction should not exceed 10 mm.
