Dust Explosion Standards
European (EN) standards are available for purchase from CENELEC National Members throughout Europe. See https://www.cenelec.eu/dyn/www/f?p=104:5 for a full list of members and their associated websites. NFPA standards may be purchase from NFPA at https://www.nfpa.org/EN 14491:2012 Dust explosion venting protective systems
This European Standard specifies the basic requirements of design for the selection of a dust explosion venting protective system. It covers vent sizing to protect an enclosure against the internal pressure effects of a dust explosion, flame and pressure effects outside the enclosure, recoil forces and the influence of vent ducts.EN 14373:2021 Explosion suppression systems
General requirements for explosion suppression components, evaluating the effectiveness of an explosion suppression system, evaluating the scale up of an explosion suppression system, evaluation and development of design tools for explosion suppression systems, instructions for installation of an explosion suppression system and maintenance instructions for an explosion suppression system.EN 14797:2006 Explosion venting devices
This European Standard specifies the requirements for venting devices used to protect enclosures against the major effects of internal explosions arising from the rapid burning of suspended dust, vapour or gas contained within. It includes the requirements for the design, inspection, testing, marking, documentation and packaging.EN 13237-1:2012 Potentially explosive atmospheres - Terms and definitions for equipment and
protective systems
This standard describes the vocabulary to be used to give all standards in this area an overall uniformity of terminology.EN 15089:2009 Explosion isolation systems
This standard sets out the criteria for alternative test methods and interpretation means to validate the efficacy of explosion isolations. It covers general requirements for the explosion isolation components, evaluating the effectiveness of an explosion isolation system and evaluating design tools for explosion isolation systems.EN ISO/IEC 80079-20-2:2016 Explosive atmospheres. Material characteristics. Combustible dusts
test methods.
Describes the test methods for the identification of combustible dust and combustible dust layers in order to permit classification of areas where such materials exist for the purpose of the proper selection and installation of electrical and mechanical equipment for use in the presence of combustible dust.NFPA 68:2018
NFPA 68 applies to the design, location, installation, maintenance, and use of devices and systems that vent the combustion gases and pressures resulting from a dust deflagration within an enclosure so that structural and mechanical damage is minimized.NFPA 69:2014
Provisions cover the following methods for explosion prevention: control of oxidant and combustible concentrations, predeflagration detection and control of ignition sources, explosion suppression, active isolation, passive isolation, deflagration pressure containment, and passive explosion suppression. Criteria are also provided for installation, inspection, and maintenance of explosion protection systems.
