ASTM F2676 - 19

Standard Test Method for Determining the Protective Performance of an Arc Protective Blanket for Electric Arc Hazards

Status : Current   Published : March 2019



1.1 This test method is used to evaluate the ability of the arc protective blankets to withstand the effects of arc flash and arc blast in a configuration in which the blanket is hung or anchored near energized equipment. Specifically, this test method is used to determine the arc protective blanket’s (1) resistance to breakopen, (2) mechanical strength, and (3) ability to self-extinguish flames following a controlled arc exposure.

1.2 This method is used to determine the performance of arc protective blankets in terms of: maximum arc current level expressed in kA and BTP (BTP) expressed as the product of arc current in kA and arc duration in number of cycles to cause breakopen (kA*cycles). Cycles are on the basis of 60 Hz.

1.3 Blanket test specimens used in this test method are test size blankets of 152 ± 5 cm (60 ± 2 in.) by 122 ± 5 cm (48 ± 2 in.). The test specimen size is for testing purposes only. Commercially available arc protective blankets either larger or smaller than the test specimen size are covered by this standard.

1.4 The arc protective blankets described in this test method are made of flame-resistant materials and are available in varying sizes and configurations based on the application.

1.5 This test method shall be used to measure and describe the properties of materials, products, or assemblies in response to incident thermal (convective and radiant) and pressure energies generated by an electric arc under controlled laboratory conditions.

1.6 The values stated in SI units shall be regarded as standard. The values given in parentheses are mathematical conversion to inch-pound or other units commonly used for arc testing.

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, which 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific precautions, see Section 7.

1.9  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.
