They are regarded as functional equivalents. Samples are also assessed for after-flaming, hole formation, melting, etc.
In the test, the arc does not last any longer than ms. The higher the value, the better the protection. 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. TC 78 – Live working rss.
The plasma clouds, flames, radiation and metal splashes from the electrodes hit the fabric during an arc blast. If the opposite is true, the material will allow burns before it breaks open. 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. 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 following test report forms are related: Requirements and tests to cover electric arc hazards to these parts of the 614882 are under development.
Protection against the hazards of an electric arc can be tested in 2 6482 This ic edition cancels and replaces the first edition published in Break open is defined as any open area at least 1. The lowest value is the one that is used in the marking of the garments.
A fabric sample is exposed to an electric arc 614822 by a 4kA class 1 or 7kA class 2 short circuit.
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. When this occurs, the fabric must provide sufficient insulation to prevent second-degree skin burns. Energy Break open Threshold: 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.
Protective clothing for work intentionally using an electric arc, e. The garments are tested and evaluated in two classes in the same test; a box test. Fill out the form and we will contact you.
The measured ATPV value is mentioned on the label. The requirements set in this standard The model requirements for welder’s clothing EN ISO are used in this standard. Our prices are in Swiss francs CHF. Electric shock hazard is irc 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. Related publications IEC Skip to main content.
lec Preview Abstract IEC Our garments are certified according to both test methods or one of them. The garments must cover the whole body. Neither is better than the other.
I would like to receive the newsletter. 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 edition constitutes jec technical revision. 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. The higher the value, the better the protection. An effective fabric used in an arc garment must provide shielding against the flame and metal splashes, as well as insulation from the intense isc.
Fill in your name and email address and receive all our updates in your mailbox. Other effects than the thermal ie of an electric arc like noise, light emissions, pressure rise, hot oil, electric shock, the consequences of lec 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. Besides fabric samples, a complete jacket also has to be tested.
