Standards

ASTM F 1891-02b and F 1959-04: ARC tests (ATPV, Ebtas and HAF) Standard

• Arc and Flame Resistant Rainwear
• Workwear for Protection from Hydrocarbon Flash Fire
• Momentary Protection from Open Flame

• Arc and Flame Resistant Rainwear
• Momentary Protection from Open Flame

• Momentary Protection from Open Flame

CAN/CGSB-155.20-2009: Workwear for protection against hydrocarbon flash fire

1.1 This standard states the minimum requirements for performance of workwear worn for protection against hydrocarbon flash fire.

1.1.1 This standard establishes performance requirements and test methods for evaluation of components used to construct workwear.

EN531:1995: Protective clothing for industrial workers exposed to heat

This European standard is applicable to protective clothing for workers exposed to heat (excluding firefighters and welders clothing). Protective clothing complying with this standard is intended to protect workers against brief contact with flame and against at least one type of heat. The heat may be in the form of convective heat, radiant heat, large molten metal splashes or a combination of these hazards.

EN533:1997: Protective clothing - limited flame spread materials and material assemblies

This European standard specifies the performance requirements for the limited flame spread properties of material assemblies used in protective clothing.  Limited flame spread materials and material assemblies are used in protective clothing in order to reduce the possibility of the clothing burning and thereby itself constituting a hazard.

ENV 470-1: Protective clothing during welding and similar operations

The clothing is intended to protect the user against small splashes of molten metal (EN 348), short contact time with flame (EN 532), and ultra violet radiation, and to be worn continuously for up to 8 hours at ambient temperature.

ENV 50354: Electrical arc protection

This standard specifies tests and classification for materials and clothing for wearing when at risk of exposure to an electrical arc. Such clothing shall not aggravate the electrical arc consequences, by catching fire or by melting onto the skin.

• Class 1: 4kA
• Class 2: 7kA

Specific dangers from accidental electrical arcs arise from the high temperature, the pressure surge and the evaporation and spatter of hot and molten metal, the effects of heat flux, noise, UV-emission, hot oil or the consequences of physical and mental shock  

EN 1149: Electrostatic properties

EN 1149 constitutes a set of requirements and test methods to measure protection against static electricity or charge decay.

EN 1149-1 specifies electrostatic requirements and test methods for electrostatic dissipative protective clothing to avoid incendiary charges. This standard is used for measuring surface resistivity of woven or kitted fabrics with metal fibres providing grounding.

EN 1149-2specifies a test method for measuring the electrical vertical resistance of protective clothing materials. This European standard is not applicable for specifying protection against main voltages.

ENV 1149-3 specifies methods for measuring the dissipation of electrostatic charge from the surface of materials for garments. This standard is used for surface conducting or core conducting fibres, i.e. fibres without grounding.
