Full Description

1.1This specification provides the minimum requirements for design, construction, performance, and testing of detonation flame arresters intended to protect against deflagrations, overdriven (unstable) detonations, stable detonations, and stabilized burning.

1.2This specification is intended for detonation flame arresters protecting systems containing gases or vapors of liquids with flash points 140F [60C] (closed cup) or less. The tests in this specification are intended to qualify detonation flame arresters for all in-line applications, provided the operating pressure is equal to or less than the maximum operating pressure determined by testing and stated in the manufacturers certification, and the diameter of the piping system in which the detonation flame arrester is to be installed is equal to or less than the piping diameter used in the testing.

1.3This specification is limited to detonation flame arresters operating at temperatures no greater than 140F [60C], unless the detonation flame arresters are tested at the higher operating temperatures.

1.4The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.5This 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.

1.6This 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.
