The following test report forms are related: I would like to receive the newsletter. Requirements and tests to cover electric arc hazards to these parts of the body are under iex. 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. This second edition cancels and replaces the first edition published in We accept all major credit cards American Express, Mastercard and VisaPayPal and 64182 transfers as form of payment.
The plasma clouds, flames, radiation and metal splashes from the electrodes hit the fabric during an arc blast. Skip to main content.
The higher the value, the better the protection. Our prices are in Swiss francs CHF. This edition constitutes a technical revision. Our garments are certified according to both test methods or one of them.
Neither is better than the other. The garments must cover the whole body.

Certified and approved garments appropriate for use in work environments where there is a risk of electric arcs. An effective fabric used in an arc garment must provide shielding against the flame and metal splashes, as well iwc insulation from the intense heat.
Break open is defined as any open area at least 1.
The requirements set in this standard The model requirements for welder’s 611482 EN ISO are used in this standard. Samples are also assessed for after-flaming, hole formation, melting, etc. Do you need a multi-user copy?
This test method is used in thee USA. A fabric sample is exposed to an electric arc produced by a 4kA class eic or 7kA class 2 short circuit. If the opposite is true, the material will allow burns before it breaks open.
This edition includes the following significant technical changes with respect to the previous edition: 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 ifc tested separately because air trapped between the fabrics also has an kec and protective effect. Energy Break open Threshold: The lowest value is the one that is used in the marking of the garments. Heat Attenuation Factor HAF is the iiec of the percentage of energy that is blocked by the material or material system. Related publications IEC 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 idc toxic influences are not covered by this document.
In the test, the arc does not last any longer than ms. 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. Protection against the hazards of an electric arc can be tested in 2 ways: Fill out the form and we will contact you.
The garments are tested and evaluated in two classes in the same test; a box test. Fill in your name and email address and receive all our updates in your mailbox. 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. When there is a risk of being exposed to an electric arc, for example, when servicing equipment iev non-arc-safe distribution plants or electrical switchboards, or when working on high voltage equipment, personnel are recommended to wear arc-approved protective clothing.
Protection of eyes, face, head, hands and feet against electric arc hazard is not covered by this document. If the material has more thermal insulation value than arc tensile strength in resistance to heat, then it will break open first. TC 78 – Live working rss. For example, jacket and trousers must be worn together with other personal protective equipment PPEincluding a helmet with protective visor, protective oec and protective footwear boots to achieve the correct level of protection.
The higher the value, the better the protection. Protective clothing for work intentionally using an electric arc, e. Besides fabric irc, a complete jacket also has to be tested.
