Live working - Protective clothing against the thermal hazards of an electric arc - Part 1-2: Test methods - Method 2: Determination of arc protection class of material and clothing by using a constrained and directed arc (box test)
- new mean values of main control parameters arc energy and incident energy based on an extended statistical database consisting of parameter values measured in four laboratories;
- reduction of validity check ranges of main control parameters;
- determination of the incident energy by averaging the two sensor values of a test (instead of considering each single sensor value);
- determination of the heat curves of transmitted incident energy and an amendment to the heat flux acceptance criterion;
- clarification of the scope;
- and selection of the arc protection classes (test classes) by the amount of the arc energy and incident energy instead of the short-circuit current.
