The measured ATPV value is mentioned on the label.
Requirements and tests to cover electric arc hazards to these parts of the body are under development. Besides fabric samples, ieec complete jacket also has to be tested. If the opposite is true, the material will allow burns before it breaks open. This test method is used in thee USA. This edition includes the following significant technical changes with respect to the previous edition: If the material has more ieec insulation value than arc tensile strength in resistance to heat, then it will break open first.
This standard was set up for clothing designed to provide protection against the thermal hazards of an electric arc. 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.
Protective clothing for work intentionally using an electric arc, e. Samples are also assessed for after-flaming, hole formation, melting, etc.
The higher the value, the better the protection. TC 78 – Live working rss.
Energy Break open Threshold: I would like to receive the newsletter. Skip to main content.
Our prices are in Swiss francs CHF. The lowest value is the one that is used in the marking of the garments. 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.
Break open is defined as any open area at least 1.
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 plasma clouds, flames, radiation and metal splashes from the electrodes hit the fabric during an arc blast. Our garments are certified according to both test methods or one of them.
This edition constitutes a technical revision. The higher the value, the better the protection.

Related publications IEC Heat Attenuation Factor HAF is ic measurement of the percentage of energy that is blocked by the material or material system. Other effects than the thermal effects of an electric arc like noise, oec emissions, pressure rise, hot oil, electric shock, the consequences of physical and mental shock or toxic influences are not covered by this document. An effective fabric used in an arc garment iwc provide shielding against the flame and metal splashes, as well as insulation from the intense heat.
The garments must cover the whole body. Protection of eyes, face, head, hands and feet against electric arc hazard is not covered by this document. The following test report forms are related: 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.
For example, jacket and trousers must be iev 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 requirements set in this standard The model requirements for welder’s clothing EN ISO are used in this standard. 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 this occurs, the fabric must provide sufficient insulation to prevent second-degree skin burns. We accept all major credit cards American Express, Mastercard and VisaPayPal and bank transfers as form of payment. Preview Abstract IEC Electric shock hazard is not covered by this document, which is applicable in combination with standards covering such hazards.
In the test, the arc does not last any longer than ms.
