1.1 This test method is used to measure the arc rating of gloves as materials intended for use as the part of flame resistant clothing and protective accessories for workers exposed to electric arc. An electric arc would generate heat flux rates from 84 to 25 120 kW/m 2 [2 to 600 cal/cm2s]. 1.2 This test method will measure the arc rating of gloves which meet the following requirements: less than 150 mm [6 in.] char length and less than 2 s afterflame when tested in accordance with Test Method D 6413. 1.2.1 It is not the intent of this test method to evaluate non flame-resistant materials except where used as under layers in multiple-layer specimens: less than 150 mm [6in.] char length and less than 2 s afterflame when tested in accordance with Test Method D6413. 1.3 This test method shall be used to measure and describe the properties of gloves in response to convective and radiant energy generated by an electric arc under controlled laboratory conditions. 1.5 The values stated in SI units shall be regarded as standard except as noted. Within the text, alternate units are shown in brackets. The values stated in each system may not be exact equivalents therefore alternate systems must be used independently of the other. Combining values from the systems described in the text may result in nonconformance with the method. 1.6 This test method does not apply to electrical contact or electrical shock hazards. 1.7 This standard shall not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire assessment that takes into account all of the factors, which are pertinent to an assessment of the fire hazard of a particular end use. 1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use. For specific precautions, see Section 7.
