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 13237-1:2003 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 overalluniformity 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.
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.
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.
Requirements apply to all phases of the manufacture, processing, blending, pneumatic conveying, repackaging, and handling of combustible particulate solids or hybrid mixtures where the materials present a fire or explosion hazard. Topics include facility and systems design and construction, identification of combustible dust flash fire or explosion hazard areas, process equipment protection, fugitive dust control and housekeeping, ignition source identification and control, fire protection, training and procedures, and inspection and maintenance.
Flash point determination by Pensky-Martens closed cup apparatus. Suitable for ﬂashpoints in the temperature range from 40°Cto 360°C.This document is supplied courtesy of Shanghai Scientific Instrument Co Ltd.Flash point temperature is the result of a flash point test and depends upon the apparatus and test method used. See flash point testingfor more detailed information.
