The objective of doing this is not to determine the energetic value, but to assess the jacket iex exposure to an electric arc for defects in the seams, fastenings and all other accessories.
The garments are tested and evaluated in two classes in the same test; a box test. Samples are also assessed for after-flaming, hole formation, melting, etc.
Do you need a multi-user copy? The measured ATPV value is mentioned on the label. I would like to receive the newsletter.
The plasma clouds, flames, radiation and metal splashes from the electrodes hit the fabric during an arc blast.
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.

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 higher the value, the better the protection. In the test, the arc does not last any longer 614882 ms. Requirements and tests to cover electric arc hazards to these parts of the body are under development. TC 78 – Live working rss.
The requirements set in this standard The model requirements for welder’s clothing EN ISO are used in this standard. This test method is used in thee USA. When this occurs, the fabric must provide sufficient insulation to prevent second-degree skin burns. Heat Attenuation Factor HAF is the measurement of the percentage of energy that is blocked by the material or material system. This second edition cancels and replaces the first edition published in Protective clothing for work intentionally using an electric arc, e.
Related publications IEC Preview Abstract IEC The higher the value, the better the protection. A fabric sample is exposed to an electric arc produced by a 4kA class 1 or 7kA class 2 short circuit.
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 of eyes, face, head, hands and feet against electric arc hazard is not covered by this document. Electric shock hazard is not covered by this document, which is applicable in combination with standards covering such hazards. The amount of heat transmitted through the sample is measured during and after the test. We accept all major credit cards American Express, Mastercard and VisaPayPal and bank transfers as form of payment.
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.
Besides fabric samples, a complete jacket also has to be tested. 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. An effective fabric used in an arc garment must provide 661482 against the flame and metal splashes, as well as insulation from the intense heat. Energy Break open Threshold: The garments must cover the whole body.
Our garments are certified according to both test methods or one of them. Protection against the hazards of an electric arc can be tested in 2 ways: Ic edition constitutes a technical revision.
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.
