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

If the opposite is true, the material will allow burns before it breaks open. In the test, the arc does not last any longer than ms. 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.
Neither is better than the other. We accept all major credit cards American Express, Mastercard and VisaPayPal and bank transfers as form of payment. The plasma clouds, flames, radiation and metal splashes from the electrodes hit the fabric during an arc blast.
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. Fill out the form and we will contact 6142. The higher the value, the better the protection. Requirements and tests to cover electric arc hazards to these parts of the body are under development.
The amount of heat transmitted through the sample is measured during and after the test. The requirements set in this standard The model requirements for welder’s clothing EN ISO are used in this standard. Besides fabric samples, a complete jacket also has to be tested.
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.
Break open is defined as any open area at least jec. Heat Attenuation Factor HAF is the measurement of the percentage of energy that is blocked by the material or material system. Our garments are certified according to both test methods or one of them. Preview Abstract IEC Our prices are in Swiss francs CHF.
Electric shock hazard is not covered by this document, which is applicable in combination with standards covering such hazards. 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. 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.
Certified and approved garments appropriate for use in work environments where there is a risk of electric arcs.
This edition includes the following significant technical changes with respect to the previous edition: This second edition cancels and replaces the first edition published in 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.

This standard was set up for clothing designed to provide protection against the thermal hazards ice an electric arc. iecc
Protective clothing for work intentionally using an electric arc, e. 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. Layering is very important and will increase protection — if you wear flame retardant underwear underneath your flame retardant garments you are protected for 61428 better.
