What is BS EN 1839-Determination of the explosion limits and the limiting oxygen concentration (LOC) about?
BS EN 1839 discusses the determination of the explosion limits and the limiting oxygen concentration (LOC) for flammable gases and vapours. BS EN 1839 is a European standard that provides methods for the determination of the explosion limits for gases and vapours and the limiting oxygen concentration (LOC) for gases and vapours to ensure safety from explosion hazards.
BS EN 1839 specifies two test methods (method T and method B) to determine the explosion limits of gases, vapours, and their mixtures, mixed with air or an air / inert gas mixture (volume fraction of the oxygen < 21 %) and the limiting oxygen concentration.
BS EN 1839 applies to gases, vapours, and their mixtures at atmospheric pressure for temperatures up to 200 °C.
Who is BS EN 1839-Determination of the explosion limits and LOC for?
BS EN 1839 on the determination of the explosion limits and LOC for gas and vapours is useful for:
- Chemical laboratories
- Chemical engineers
- Occupational health and safety departments
- Risk assessment departments
Why should you use BS EN 1839-Determination of the explosion limits and LOC?
The hazard of an explosion can be avoided by preventing the formation of explosive mixtures of gases and/or vapours with air. To do so, the explosion limits (also known as “flammability limits”) or the limiting oxygen concentration of the flammable substance need to be known. These limits depend on the properties of the flammable substance, temperature, and pressure, size and shape of the test vessel, ignition source (type, energy), the criterion for self-propagating combustion, the inert gas.
BS EN 1839 provides you with tube method, bomb method, apparatus, equipment for preparing the test, procedures, method for determination of the explosion limits and limiting oxygen concentration of substances that are difficult to ignite, and much more.
The test methods and procedures provided by BS EN 1839 assist you in determining the explosion limits and the limiting oxygen concentration (LOC) for flammable gases and vapours and ensure protection to workers from the negative health effects of workplace exposure to chemicals and substances.
By adopting BS EN 1839 you can establish solutions for eliminating or reducing the hazard to enhance safety measures and ensure occupational health and safety.
What is changed since the last update?
BS EN 1839:2017 supersedes BS EN 14756:2006 and BS EN 1839:2012, which is withdrawn. BS EN 1839:2017 has made some technical changes in requirements and minor editorial changes compared to the previous edition BS EN 14756:2006 and BS EN 1839:2012.
