This edition constitutes a technical revision. 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. 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. Our garments are certified according to both test methods or one of them. This test method is used in thee USA.
We accept all major credit cards American Express, Mastercard and VisaPayPal and bank transfers as form of payment. 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. Heat Attenuation Factor HAF is the measurement of the percentage of energy that is blocked by the material or material system.
I would like to receive the newsletter. Neither is better than 614882 other. The plasma clouds, flames, radiation and metal splashes from the electrodes hit the fabric during ieec arc blast. Break open is defined as any open area at least 1.
This second edition cancels and replaces the first edition published in Requirements and tests to cover electric arc hazards to these parts of the body are under development. Related publications IEC Protection against the hazards of an electric arc can be tested in 2 ways: Certified and approved garments appropriate for use in work environments where there is a risk of electric arcs.

The lowest value is the one that is used in the marking of the garments. Besides fabric samples, a complete jacket also has to uec tested.
This standard was set up for clothing designed to provide protection against the thermal hazards of an electric arc. The garments are tested and evaluated in two classes in the same test; a box test. When you test multiple layers, you will achieve a higher value 611482 if the fabrics were tested separately because air trapped between the fabrics also has an insulating and protective effect.
Electric shock hazard is not covered by this document, which is applicable in combination with standards covering such hazards.
Samples are also assessed for after-flaming, hole formation, melting, etc.
They are regarded as functional equivalents. A fabric sample is exposed to an electric arc produced by a ief class 1 or 7kA class 2 short circuit.

For example, jacket and trousers must be worn together with other personal protective equipment PPEief a helmet with protective visor, protective gloves and protective footwear boots to achieve the correct level of protection. 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.
This edition includes the following significant technical changes with respect to the previous edition: Fill out the form and we will contact you. Irc Abstract IEC Protective clothing for work intentionally using an electric arc, e.
The requirements set in this standard The model requirements for welder’s clothing EN ISO are used in this standard. Skip to main content.
Energy Break open Threshold: Our prices are in Swiss francs CHF. 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. The amount of heat transmitted through the sample is measured during and after the test.
Protection of eyes, face, head, hands and feet against electric arc hazard is not covered by this document. The garments must cover the whole body.
If the opposite is true, the material will allow burns before it breaks open.
