This test method is used in thee USA.
The garments must cover the whole body. They are regarded as functional equivalents. Samples are also assessed for after-flaming, hole formation, melting, etc. The garments are tested and evaluated in two classes in the same test; a box test.
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. Protection of eyes, face, head, hands and feet against electric arc hazard is not covered by this document. Our garments are ifc according to both test methods or one of them. The higher the value, the better the protection.
Energy Break open Threshold: Layering is very important and will increase protection — if you wear flame retardant underwear underneath your flame retardant garments you are protected for even better.
The requirements set in this standard The model requirements for welder’s clothing EN ISO are used in this standard. The higher the value, the better the protection. Related publications IEC TC 78 – Live working rss. In the test, the arc does not last any longer than ms.

Requirements and tests to cover electric arc hazards to these parts of the body are under development. The plasma clouds, flames, radiation and metal splashes from the electrodes hit the fabric during an arc blast. If the opposite is true, the material will allow burns before it breaks open. The amount of heat transmitted through the sample is measured during and after the test. A fabric sample is exposed to an electric arc produced by a 4kA class 1 or 7kA class 2 short circuit.
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.
Skip to main content. Certified and approved garments appropriate for use in work environments where there is a risk of electric arcs. If the material has more thermal insulation value than arc tensile strength in resistance to heat, then it will break open first.
This edition includes the following significant technical changes with respect to the previous edition: 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.
Break open is defined as any open area at least 1.
Protective clothing for work intentionally using an electric arc, e. Electric shock hazard is not covered by this document, which is applicable in combination with standards covering such hazards. I would like to receive the newsletter.
This standard was set up for clothing designed to provide protection against the thermal hazards of an electric arc. We accept all ice credit cards American Express, Mastercard and VisaPayPal and bank transfers as form of payment.
