Heat Attenuation Factor HAF is the measurement of the percentage of energy that is blocked by the material or material system. The following test report forms are related: I would like to receive the newsletter.

Besides fabric samples, a complete jacket also has to be tested. Neither is better than the other. The measured ATPV value is mentioned on the label. 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. When this occurs, the fabric must provide sufficient insulation to prevent second-degree skin burns. On the basis of the resulting data and a STOLL curve, the length of time it would take to cause the onset of second-degree burns is subsequently determined.

An effective fabric used in an arc garment must provide shielding against the flame and metal splashes, as well as insulation from the intense heat. This test method is used in thee USA.

This standard was set up for clothing designed to provide protection against the thermal hazards of an electric arc. The higher the value, the better the protection. Certified and approved garments appropriate for use in work environments where there is a risk of electric arcs.

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. Protection against the hazards of an electric arc can be tested in 2 ways: They are regarded as functional equivalents.

Our garments are certified according to both test methods or one of them. The garments are tested and evaluated in two classes in the same test; a box test. If the opposite is true, the material will allow burns before it breaks open. Samples are also assessed for after-flaming, hole formation, melting, etc.

Energy Break open Threshold: We use cookies in order to recognize the preferences of our website visitors and improve the content of our site accordingly. 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.

The lowest value is the one that is used in the marking of the garments. The amount of heat transmitted through 61842 sample is measured during and after the test. By clicking anywhere on our website you will accept 6148 cookie policy.

For example, jacket and trousers must be worn together with other personal protective equipment PPEincluding a helmet with protective visor, protective gloves and protective footwear boots to achieve the correct level of protection. The plasma clouds, flames, radiation and metal splashes from the electrodes hit the fabric during an arc blast. Break open is defined as any open area at least 1.

Electric shock hazard is not covered by this document, which is applicable in combination with standards covering such hazards. Skip to main content. Protective clothing for work intentionally using an electric arc, e.

This document specifies requirements and test methods applicable to materials and garments for protective clothing for electrical workers against the thermal hazards of an electric arc.

If the material has more thermal insulation value than arc tensile strength in resistance to heat, then it will break open first. This second edition cancels and replaces the first edition published in The garments must cover the whole body. TC 78 – Live working rss. 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.

A fabric sample is exposed to an electric arc produced by a 4kA class 1 or 7kA class 2 short circuit.
