ieec Fill out the form and we will contact you. Heat Attenuation Factor HAF is the measurement of the percentage of energy that is blocked by the material or material system. A fabric sample is exposed to an electric arc produced by a 4kA class 1 or 7kA class 2 short circuit. We accept all major credit cards American Express, Mastercard and VisaPayPal and bank transfers as form of payment.
When this occurs, the fabric must provide sufficient insulation to prevent second-degree skin burns. 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 measured ATPV value is mentioned on the label.
Protection of eyes, face, head, hands and feet against electric arc hazard is not covered by this document.

The lowest value is the one that is used in the uec of the garments. The amount of heat transmitted through the sample is measured during and after the test. Do you need a multi-user copy? This edition constitutes a technical revision. Preview Abstract IEC 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.
Samples are also assessed for after-flaming, hole formation, melting, etc. This edition includes the following significant technical changes with respect to the previous edition: If the opposite is true, the material will allow burns before it breaks open.
This second edition iex and replaces the first edition published in The higher the value, the better the protection. Our prices are in Swiss francs CHF. 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.
If the material has more thermal insulation value than arc tensile strength in resistance to heat, then it will break open first. Protective clothing for work intentionally using an electric arc, e. When you test multiple layers, you will achieve a 61842 value then if the fabrics were tested separately because air trapped between the fabrics also has an insulating and protective effect.
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. Neither is better than the other. The plasma clouds, flames, radiation and metal splashes from the electrodes hit the fabric during an arc blast.
Besides fabric samples, a complete jacket also has to be tested.
Protection against the hazards of an electric arc can be tested in 2 ways: This document specifies requirements and test methods applicable to materials and 61842 for protective clothing for electrical workers against the thermal hazards of an electric arc.
Skip to main content. Related publications IEC They are regarded as functional equivalents. The garments are tested and evaluated in two classes in the same test; a box test. Our garments are certified according to both test methods or one of them. The requirements set in this standard The model requirements for welder’s clothing EN ISO are used in this standard. Other effects than ic 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 ied by this document.
I would like to receive the newsletter. The garments must cover the whole body.
