Eic and approved garments appropriate for use in work environments where there is a risk of electric arcs. The requirements set in this standard The model requirements for welder’s clothing EN ISO are used in this standard.

Layering is very important and will increase protection — if you wear flame retardant underwear underneath your flame retardant garments kec are protected for even better. On the basis of the resulting data 6148 a STOLL curve, the length of time it would take to cause the onset of second-degree burns is subsequently determined.

Requirements and tests to cover electric ie hazards to these parts of the body are under development.

Besides fabric samples, a complete jacket also has to be tested. Neither is better than the other. The garments must cover the whole body. Other effects than the thermal effects of an electric arc like noise, light emissions, pressure rise, hot oil, electric shock, the consequences of physical and mental shock or toxic influences are not covered by this document.

A fabric sample is exposed to an electric arc produced by a 4kA class 1 or 7kA class 2 short circuit. I would like 614822 receive the newsletter. The garments are tested and evaluated in two classes in the same test; a box test. The objective of doing this is not to determine the energetic value, but to assess the jacket after exposure to an electric arc for defects in the seams, fastenings and all other accessories.

When you test multiple layers, you will achieve a higher value then if the fabrics were tested separately because air trapped between the fabrics also has an insulating and protective effect. The measured ATPV value is mentioned on the label. Skip to main content. TC 78 – Live working rss.


If the material has more thermal insulation value than arc tensile strength in resistance to heat, then it will break open first. Heat Attenuation Factor HAF is the measurement of the percentage of energy that is blocked by the material or material system.

An effective fabric used in an arc garment must provide shielding against the flame and metal splashes, as well eic insulation from the intense heat.

This edition includes the following significant technical changes with respect to the previous edition: The higher the value, the better the protection. Our garments are certified according to both test methods or one of them. When there is a risk of being exposed to an electric arc, for example, when servicing equipment in non-arc-safe distribution plants or electrical switchboards, or when working on high voltage equipment, personnel are recommended to wear arc-approved protective clothing.

The higher the value, the better the protection.
