Potentially explosive atmospheres - Explosion prevention and protection - Guidance on inerting for the prevention of explosions
CEN/TR 15281:2022

Inerting is a measure to prevent explosions. By feeding inert gas into a system which is to be protected against an explosion, the oxygen content is reduced below a certain concentration until no explosion can occur. The addition of sufficient inert gas to make any mixture non-flammable when mixed with air (absolute inerting) is only required in rare occasions. The requirements for absolute inerting will be discussed. Inerting may also be used to influence the ignition and explosion characteristics of an explosive atmosphere.
The guidance given on inerting is also applicable to prevent an explosion in case of a fire.
The following cases are not covered by the guideline:
-   admixture of an inert dust to a combustible dust;
-   inerting of flammable atmospheres by wire mesh flame traps in open spaces of vessels and tanks;
-   fire fighting;
-   avoiding an explosive atmosphere by exceeding the upper explosion limit of a flammable substance.
Inerting which is sufficient to prevent an explosion is not a protective measure to prevent fires, self-ignition, exothermic reactions or a deflagration of dust layers and deposits.

Use of plugs of bulk material in screw conveyors and product receivers for explosion isolation
CEN/TR 17838:2022

Screw conveyors are mechanical devices for the continuous move, discharge or variable rate
feeding of bulk materials in form of powder, granules or grain. They are often used
horizontally or at a slight incline to discharge or feed silos, storage bins, cyclones, filter units,
mills or other equipment in many bulk handling industries.
This Technical Report describes requirements on screw conveyors which can in addition be
used as explosion isolation systems to prevent a dust explosion transmission into connected
plant items.
The scope of this technical report is limited to rigid tubular screw conveyors which consist of
a spiral blade coiled around a shaft held in external bearings (the rotating part of the
conveyor is sometimes called “auger”). Additional internal bearings can be necessary if the
tubular screw conveyor exceeds a certain length.

Determination of maximum explosion pressure and the maximum rate of pressure rise of gases and vapours
EN 15967:2022

The European Standard test method is designed to produce measurements of explosion pressure and the maximum explosion pressure, the rate of explosion pressure rise and the maximum rate of explosion pressure rise of a quiescent flammable gas/air/inert mixture in closed volume at ambient temperature and pressure. In this European Standard, the term "gas" includes vapours but not mists. Detonation and decomposition phenomena are not considered in this European Standard.
The pressures and rates of pressure rise measured by the procedures specified in this European Standard are not applicable to flameproof enclosures, that is enclosures intended to withstand an internal explosion and not to transmit it to an external explosive atmosphere, or any other closed volume where the internal geometry can result in pressure piling. Even in an enclosure of relatively simple geometry the disposition of the internal components can lead to rates of pressure rise significantly higher than those measured using this European Standard. This European Standard does not apply to the design and testing of flameproof enclosures in conformity with EN 13463-6 (for non-electrical equipment) and EN 60079-1 (for electrical equipment).

Determination of the spontaneous ignition behaviour of dust accumulations
EN 15188:2020

This European Standard specifies analysis and evaluation procedures for determining self-ignition temperatures (TSI) of combustible dusts or granular materials as a function of volume by hot storage experiments in ovens of constant temperature. The specified test method is applicable to any solid material for which the linear correlation of lg (V/A) versus the reciprocal self-ignition temperature 1/TSI (with TSI in K) holds (i.e. not limited to only oxidatively unstable materials).
This European Standard is not applicable to the ignition of dust layers or bulk solids under aerated conditions (e.g. as in fluid bed dryer).
This European Standard shall not be applied to dusts like recognised explosives that do not require atmospheric oxygen for combustion, nor to pyrophoric materials.
NOTE   Because of regulatory and safety reasons "recognised explosives" are not in the scope of this European Standard. In spite of that, substances which undergo thermal decomposition reactions and which are not "recognised explosives" but behave very similarly to self-ignition processes when they decompose are in the scope. If there are any doubts as to whether the dust is an explosive or not, experts should be consulted.

Fire and explosion prevention and protection for bucket elevators
CEN/TR 16829:2016+AC:2019

This European Technical Report applies to bucket elevators that may handle combustible products capable of producing potentially explosive atmospheres of dust or powder inside the bucket elevator during its operation. The precautions to control ignition sources will also be relevant where the product in the bucket elevator creates a fire risk but not an explosion risk.
For the purposes of this report, a bucket elevator is defined as an item of bulk material handling equipment that carries material in powder form or as coarse products such as whole grain, wood chips or flakes, in a vertical direction by means of a continuous movement of open containers.
This Technical Report specifies the principles of and guidance for fire and explosion prevention and explosion protection for bucket elevators.
Prevention is based on the avoidance of effective ignition sources, either by the elimination of ignition sources or the detection of ignition sources.
Explosion protection is based on the application of explosion venting, explosion suppression or explosion containment and explosion isolation rules specifically adapted for bucket elevators. These specific rules may be based on agreed test methods.
This European Technical Report does not apply to products that do not require atmospheric oxygen for combustion.
