(Test Method)Standard Test Method for Determining Dielectric Strength of Dielectric Footwear
Standard Test Method for Determining Dielectric Strength of Dielectric Footwear
SIGNIFICANCE AND USE
4.1 Electrical contact injuries to workers may involve a current path through the feet of the worker. The footwear covered by this specification is dielectrically rated to provide additional insulation and isolation to the wearer. This test method will determine that dielectric footwear has dielectric integrity at the time of the test.
SCOPE
1.1 This test method covers testing to determine the “Dielectric Strength” of dielectric overfoot and overshoe footwear. Testing is done over the maximum possible area of the dielectric footwear without permitting flashover between electrodes.
1.2 The use and maintenance of dielectric footwear is beyond the scope of this test method.
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements appear in 5.2.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
