Dt119

Reference standard, not for use alone, but only in association with another standard containing the protection performance requirements. This standard specifies general performance requirements for ergonomics, innocuousness, size designation, durability, ageing, compatibility and marking of protective clothing and the information to be supplied by the manufacturer with the protective clothing.

Requirements for chemical protection clothing with liquid-tight (type 3) or spray-tight (type 4) connections, including items providing only partial body protection (types PB [3] and PB [4]). This standard sets out the minimum requirements for the following types of limited use and re-useable chemical protective clothing: – Clothing protecting the full body with liquid-tight connections between the various clothing parts (Type 3: liquid-tight clothing) ; – Clothing protecting the full body with spray-tight connections between the various clothing parts (Type 4: spray-tight clothing) ; Note: These standards were formerly entitled EN1512 (Type 4) and EN1511 (Type 3).

Performance requirements for protective clothing against chemical products offering full body protection against air-borne solid particulates (type 5 clothing). This standard sets out the minimum requirements for chemical protection clothing resisting penetration of solid particulates suspended in air (type 5). This clothing offers full body protection, including the torso, arms and legs, such as one or two-piece coveralls, with or without hood or face-shield, with or without foot protection.

This standard specifies the requirements and test methods for non ventilated protective clothing against radioactive contamination in the form of particles. Clothing of this type is designed only to protect the body, the arms and the legs of the wearer, but it may be used with accessories that protect other parts of the wearer’s body (for example, boots, gloves, respiratory protective device – APR). The garments are classified according to their nominal protection factor (ratio between the concentration of test particles in the ambient atmosphere and the concentration of test particles inside the garment), determined in relation to the total inward leakage (ratio between the concentrations of test particles insider the garment and inside the test chamber). The classes are as follows: – CLASS 1: Nominal protection factor 5 – CLASS 2: Nominal protection factor 50 – CLASS 3: Nominal protection factor 500

This European Standard specifies requirements for materials and the design of protective electrostatic dissipation clothing used in conjunction with a grounded system in order to prevent incendiary discharges. WARNING: These requirements may be insufficient in oxygen enriched flammable environments. This standard is not applicable for protection against mains voltages. The control of undesirable static electricity on the person is often necessary. The electrostatic potential may, indeed, have serious consequences on the charged individual, because it can be high enough to cause dangerous sparks. After a risk assessment, the wearing of protective electrical dissipation clothing may be necessary. The use of clothing certified according to EN1149-5 is then adapted. The ATEX Directive 1999/92/EC, in its Annex II-A-2.3, requests that workers be equipped with work clothes made of materials that do not produce electrostatic discharges that can ignite explosive environments. The electrostatic potential can also affect equipment sensitive to electric discharge. And antistatic clothing are often used on electronic manufacturing sites, assembling semiconductors for example. Finally, they are used on sites with controlled atmospheres such as automotive paint workshops, to avoid the emission of particles that may be deposited on the body paint. The antistatic charge dissipation can be provided by a process limiting the build up of charge, or by adding carbon or metal wires. People wearing protective electrostatic charge dissipation clothing must always be grounded with a resistance of less than 10⁸Ω, for example, by wearing appropriate footwear such as the safety shoes stated in EN ISO 20345, or by other suitable means.
