Protective clothing for work intentionally using an electric 661482, e. The measured ATPV value is mentioned on the label. Samples are also assessed for after-flaming, hole formation, melting, etc. 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. Certified and approved garments appropriate for use in work environments where there is a risk of electric arcs.
Requirements and tests to cover electric arc hazards to these parts of the body are under development. Break open is defined as any open area at least 1. 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 6482 of an electric arc. 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. If the opposite is true, the material will allow burns before it breaks open.
They are regarded as functional equivalents.

An effective fabric used in an arc garment must provide shielding against the flame and metal splashes, as idc as insulation from the intense heat. Besides fabric samples, a complete jacket also has to be tested.
This test method is used in thee USA. TC 78 – Live working rss. In the test, the arc does not last any longer than ms. Neither is better than the other. Heat Attenuation Factor HAF is the measurement of the percentage of energy that is blocked by the material or material system.
If the material has more thermal 614822 value than arc tensile strength in resistance to heat, then it will break open first.
Electric shock hazard is not covered by this document, which is applicable in combination with standards covering such iwc. 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.
Do you need a multi-user copy? The lowest value is the one that is used in the marking of the garments.
Layering is very important and will increase protection — if you wear flame retardant underwear underneath irc flame retardant garments ief are protected for even better. Fill in your name and email address and receive all our updates in your mailbox. Our garments are certified according to both test methods or one of them. When this occurs, the fabric must provide sufficient insulation to prevent second-degree skin burns. The higher the value, the better the protection.
The following test report forms are related: Protection against the hazards of an electric arc can be tested in 2 ways: Fill out the form and we will contact you. This edition constitutes a technical revision. We accept all major credit cards American Express, Mastercard and VisaPayPal and bank transfers as form of payment.
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. This edition includes the following significant technical changes with respect to the previous edition: The amount of heat transmitted through the sample is measured during and after the test.
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.
