EN Standards for Dust Explosions European standards are available from agencies throughout Europe, such as the British Standards Institution. The links below are provided courtesy of the Industrial Explosion Protection Institute (IEPI). EN 14491:2006 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 14373:2005 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 1127-1:2007 Explosive atmospheres, basic concepts and methodology Specifies methods for the identification and assessment of hazardous situations leading to explosion and the design and construction measures appropriate for the required safety. This is achieved by hazard identification, risk assessment, reduction of risk and information for use. 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. NFPA Standards for Dust Explosions Store Products © copyright 2011 NFPA 68:2007 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. As part of its revision, the 2007 standard includes a performance-based option, including two new chapters supporting the performance-based aspect. NFPA 69:2008 NFPA 69 applies to the systems and equipment used for the prevention of explosions by the prevention or control of deflagrations, including two new chapters to incorporate a performance- based approach for compliance, in addition to the more traditional specification-based option. The concept of safety integrity levels (SIL) for safety instrumented systems was added to the standard to address aspects of system reliability and chapters on Detection and Ignition Control and Suppression were updated and expanded. Requirements for explosion prevention control by isolation have been expanded in two chapters – one on passive isolation techniques and another on active techniques. NFPA 654:2008 This Standard provides requirements for safety to life and property from fire and explosion associated with the manufacturing, processing, blending, pneumatic conveying, repackaging and handling of combustible particulate solids or hybrid mixtures.
