Live working - Protective clothing against the thermal hazards of an electric arc - Part 1-1: Test methods - Method 1: Determination of the arc rating (ELIM, ATPV and/or EBT) of clothing materials and of protective clothing using an open arc
IEC 61482-1-1:2019 specifies test method procedures to determine the arc rating of flame resistant clothing materials and garments or assemblies of garments intended for use in clothing for workers if there is an electric arc hazard.An open arc under controlled laboratory conditions is used to determine the values of ELIM, ATPV or EBT of materials, garments or assemblies of garments.NOTE 1?The user can, if he desires, classify the arc protective performance into arc rating protection levels based on ELIM, ATPV and/or EBT values which correspond best to the different hazard and risks levels that can result from the user?s risk analysis.NOTE 2?This document is not dedicated to classifying the arc protective performance of the material and clothing into arc protection classes. Procedures determining these arc protection classes APC1 and APC2 are specified in IEC 61482 1-2, which uses a constrained arc for testing.NOTE 3?This test method is not intended and not appropriate to evaluate whether materials or garments are flame resistant or not, as this is covered in IEC 61482-2.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.Protective clothing for work intentionally using an electric arc, e.g. arc welding, plasma torch, is not covered by this document.This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous edition:- addition of the Incident energy limit (ELIM) as a further arc rating performance property value;- replacement of char length requirement in the scope by indication that Procedure A is applicable for testing of materials meeting the limited flame spread requirements of IEC 61482-2;- clarification of the definition and the meaning of the Stoll curve;- modification of specification of positioning of monitor sensors with respect to the electric arc as function of intended high incident energy exposure of test specimens;- modification of specifications of monitor sensor construction;- specification of black paint;- elimination of calorimeters from the chest of the mannequin;- specification for possible positioning of mannequin(s) at a height different from the centre of the electric arc and possible turning in order to adequately expose all parts of the garment or clothing which would affect performance;- more explicit description of requirements for data acquisition system;- preconditioning of the samples;- modification of requirements for apparatus and arc exposure verification by bare shots;- more explicit description of test procedures A and B, in particular the subclauses dealing with ?sequence of test?, ?test parameter? and ?test criteria?;- addition of determination of arc rating values of garments and/or garmet assemblies.Key words: Protective Clothing, Thermal Hazards, Open Arc, Arc Rating

Live working - Protective clothing against the thermal hazards of an electric arc - Part 1-1: Test methods - Method 1: Determination of the arc rating (ELIM, ATPV and/or EBT) of clothing materials and of protective clothing using an open arc
IEC 61482-1-1:2019 specifies test method procedures to determine the arc rating of flame resistant clothing materials and garments or assemblies of garments intended for use in clothing for workers if there is an electric arc hazard.
An open arc under controlled laboratory conditions is used to determine the values of ELIM, ATPV or EBT of materials, garments or assemblies of garments.
NOTE 1?The user can, if he desires, classify the arc protective performance into arc rating protection levels based on ELIM, ATPV and/or EBT values which correspond best to the different hazard and risks levels that can result from the user?s risk analysis.
NOTE 2?This document is not dedicated to classifying the arc protective performance of the material and clothing into arc protection classes. Procedures determining these arc protection classes APC1 and APC2 are specified in IEC 61482 1-2, which uses a constrained arc for testing.
NOTE 3?This test method is not intended and not appropriate to evaluate whether materials or garments are flame resistant or not, as this is covered in IEC 61482-2.
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.
Protective clothing for work intentionally using an electric arc, e.g. arc welding, plasma torch, is not covered by this document.
This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
- addition of the Incident energy limit (ELIM) as a further arc rating performance property value;
- replacement of char length requirement in the scope by indication that Procedure A is applicable for testing of materials meeting the limited flame spread requirements of IEC 61482-2;
- clarification of the definition and the meaning of the Stoll curve;
- modification of specification of positioning of monitor sensors with respect to the electric arc as function of intended high incident energy exposure of test specimens;
- modification of specifications of monitor sensor construction;
- specification of black paint;
- elimination of calorimeters from the chest of the mannequin;
- specification for possible positioning of mannequin(s) at a height different from the centre of the electric arc and possible turning in order to adequately expose all parts of the garment or clothing which would affect performance;
- more explicit description of requirements for data acquisition system;
- preconditioning of the samples;
- modification of requirements for apparatus and arc exposure verification by bare shots;
- more explicit description of test procedures A and B, in particular the subclauses dealing with ?sequence of test?, ?test parameter? and ?test criteria?;
- addition of determination of arc rating values of garments and/or garmet assemblies.

Live working - Protective clothing against the thermal hazards of an electric arc - Part 1-1: Test methods - Method 1: Determination of the arc rating (ATPV or E<sub>BT50</sub>) of flame resistant materials for clothing
IEC 61482-1-1:2009 specifies test methods to measure the arc thermal performance value of materials intended for use in heat- and flame-resistant clothing for workers exposed to the thermal effects of electric arcs and the function of garments using these materials. These test methods measure the arc thermal performance value of materials which meet the following requirements: less than 100 mm char length and less than 2 s afterflame after removal from flame, when tested in accordance with ISO 15025, procedure B (bottom-edge ignition) on the outer material, and the char length measured using a modified ISO method as described in Annex A. These methods are used to measure and describe the properties of materials, products, assemblies or garments, in response to convective and radiant energy generated by an electric arc in open air under controlled laboratory conditions. The materials used in these methods are in the form of flat specimens for method A and garments for method B. Method A is used to determine the arc rating of materials and material assemblies when tested in a flat configuration. Method B is used to measure garment response, not arc rating, to an arc exposure including all the garment findings, sewing thread, fastenings, fabrics and other accessories when tested on a male mannequin torso. Method B is also used for accident replication.
