International Standard for Flame Arresters – ISO 16852

As of January 1st, 2011 the EN 12784 was superseded by EN ISO 16852 as a harmonised standard under the Directive 94/9/EC. The ISO Standard ISO 16852 was adopted as a European Standard EN ISO 16852:2010 „Flame arresters – Performance requirements, test methods and limits for use“. It thus supersedes EN 12874 having an identical title. This Standard was not superseded for safety engineering reasons. The new standard was adopted to extend the standard's scope beyond Europe. Flame arresters which conform to EN 12874, hence, continue satisfying the basic safety and health requirements set forth in the Directive 94/9/EC.
Work is already in hand to revise the ISO Standard; another update has become necessary to cover in particular the testing of high-velocity vent valves.

Standards for venting atmospheric and low-pressure storage tanks - ISO 28300 and API 2000

The international standard ISO 28300 and the standard API 2000, Sixth Edition are identical contentwise and cover the normal venting as well as the normal and emergency vapour venting requirements for aboveground liquid petroleum or petroleum products storage tanks and underground refrigerated storage tanks, designed for operation at pressures from full vacuum through 1.034 barg (15 psig). Discussed in this Standard entitled “Petroleum, petrochemical and natural gas industries - Venting atmospheric and low-pressure storage tanks“, are the causes of overpressure and vacuum; determination of venting requirements; means of venting; selection, and installation of venting devices; and testing and marking of relief devices. This Standard is intended for tanks containing petroleum and petroleum products but is can also be applied to tanks containing other liquids.

Safety Design Principles Standards Committee (NASG)

Being a multi-subject committee, the NASG is in charge of standardization work with regard to testing and use of explosion protection devices (except flame arresters). The Directive 94/9/EC is applicable to equipment and protective systems intended for use in potentially explosive atmospheres (ATEX). This Directive defines basic safety and health requirements that need to be satisfied by manufacturers of such equipment and systems. The NASG takes an active part in formulating standards which put in concrete terms and detail the basic requirements set forth in the Directive. Standardization covers explosion suppression systems or protection systems for pressure relief, and many more subjects.
