35、61482 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 per

36、formance 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

37、 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 met

38、hods 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 gar

39、ment findings, sewing thread, fastenings, fabrics and other accessories when tested on a male mannequin torso. Method B is also used for accident replication. It is the responsibility of the user of this part of IEC 61482 to establish appropriate safety and health practices prior to use. For specifi

40、c precautions, see Clause 7. The test methods in this part of IEC 61482 are not directed to classify by protection classes. Methods determining protection classes are prescribed in IEC 61482-1-2. 2 Normative references The following referenced documents are indispensable for the application of this
