Potentially explosive atmospheres - Explosion prevention and protection - Determination of minimum ignition energy of dust/air mixtures

Potentially explosive atmospheres - Explosion prevention and protection - Determination of minimum ignition energy of dust/air mixtures

This EN specifies a method of test to determine the minimum ignition energy of a dust/air mixture by an electrically generated spark. It is intended that the dust be tested in a form representing conditions of actual use so that assessment of the hazard present can be made. Ignition energies determined by this method would be compared with ignition by a pointed source. This EN is applicable to the determination of the minimum ignition energy of a combustible dust dispersed in air, referred to hereafter as a "dust/air mixture".

Explosionsfähige Atmosphären - Explosionsschutz - Bestimmung der Mindestzündenergie von Staub/Luft-Gemischen

Diese Europäische Norm legt ein Prüfverfahren zur Bestimmung der Mindestzündenergie eines Staub/Luft-Gemisches durch einen elektrisch erzeugten Funken fest.
Dieses Prüfverfahren ist nicht geeignet für die Anwendung bei Sprengstoffen, Schießpulvern, Dynamit, Stoffen, die keinen Sauerstoff zur Verbrennung benötigen, pyrophoren Stoffen, oder Stoffen oder Stoffgemischen, die sich gegebenenfalls ähnlich verhalten können wie die vorgenannten Stoffe. Wenn irgendein Zweifel über das Vorhandensein einer Gefährdung auf Grund von Explosivstoffeigenschaften des Staubes besteht, sollten Fachleute zu Rate gezogen werden.
WARNHINWEIS - Es ist wichtig, Vorsichtsmaßnahmen gegen Brand  und Explosionsgefahr und/oder die Gefahr durch giftige Verbrennungsprodukte zu ergreifen, um die Gesundheit des Prüfpersonals zu schützen.

Atmosphères explosibles - Prévention et protection contre l'explosion - Détermination de l'énergie minimale d'inflammation des mélanges poussière/air

CEN/TR 15281:2022(Main)
Potentially explosive atmospheres - Explosion prevention and protection - Guidance on inerting for the prevention of explosions
SIST-TP CEN/TR 15281:2023

Inerting is a preventive measure to avoid explosions or fire to happen. By feeding inert gas into a system, which is to be protected against an explosion or a fire, the oxygen content is reduced below a certain limit or completely replaced by an inert gas, depending on the inert gas, on the fuel and the process until no explosion or fire can occur or develop.
Inerting can be used to prevent fire and explosion by reducing the O2 content.
NOTE Inerting can also be used to prevent and to extinguish smouldering nests and glowing fires which are a primary source of ignition in pulverized fuel storage and handling facilities, substituting air by sufficient inert gas inside the equipment.
The following cases are not covered by the guideline:
- admixture of an inert solid powder to a combustible dust;
- inerting of flammable atmospheres by wire mesh flame traps in open spaces of vessels and tanks;
- firefighting;
- avoiding an explosive atmosphere by exceeding the upper explosion limit of a flammable substance;
- anything related to product quality (oxidation or ingress of humidity) or product losses;
- any explosive atmosphere caused by other oxidizing agents than oxygen.
Other technologies might be used in combination with inerting such as floating screens made of independent collaborative floaters consisting of an array of small floaters non-mechanically linked but overlapping each other in order to form a continuous layer covering the liquid surface.
Product oxidation or evaporation reduction is directly proportional to the surface area covering ratio and quality of the inerting.

CEN/TR 17838:2022(Main)
Use of plugs of bulk material in screw conveyors and product receivers for explosion isolation
SIST-TP CEN/TR 17838:2022

This document describes the recommendations for the design and use of screw conveyors and product receivers which can in addition be used as a means for explosion isolation to prevent a dust explosion transmission into connected plant items by using the bulk material which is inside.
The recommendations given in this document are procedural measures since the properties of the bulk material affect the efficacy of this measure essentially (e.g. flow and explosion characteristics). Product receivers and screw conveyors cannot be considered as protective systems under the scope of the ATEX Directive.
As far as screw conveyors are concerned, the scope of this document is limited to rigid, tubular, singular screw conveyors which consist of a spiral blade coiled around a shaft held by external bearings (the rotating part of the conveyor is sometimes called “auger”).
NOTE   Additional internal bearings can be necessary if the tubular screw conveyor exceeds a certain length.
This document includes limits of application where a plug of bulk material in a screw conveyor is not possible/sufficient to achieve explosion isolation and also application ranges where a plug of bulk material is not necessary to achieve explosion isolation.
This document does not address the mandatory risk analysis and ignition hazard assessment, which are performed for the application of the screw conveyors and product receivers. The mandatory risk assessment includes start-up and shut-down conditions, when potentially no plug of material is present to prevent explosion propagation. To mitigate this residual risk, it is possible to use as an extra measure, e.g. a traditional gate valve which prevents flame transmission and is able to withstand the expected maximum explosion pressure.

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

This document specifies a test method that is designed to measure the 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 document, the term “gas” includes vapours but not mists. Detonation and decomposition phenomena are not considered in this document.
The pressures and rates of pressure rise measured by the procedures specified in this document are not applicable to flameproof enclosures, i.e. 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 document. This document does not apply to the design and testing of flameproof enclosures in conformity with EN ISO 80079-37 (for non-electrical equipment) and EN 60079-1 (for electrical equipment).

Explosion suppression systems
SIST EN 14373:2022

This document describes the basic requirements for the design and application of explosion suppression systems. This document also specifies test methods for evaluating the effectiveness and the scaling up of explosion suppression systems against defined explosions. This document covers:
-   general requirements for explosion suppression system parts;
-   evaluating the effectiveness of an explosion suppression system;
-   evaluating the scale up of an explosion suppression system to larger than tested volumes;
-   development and evaluation of design tools for explosion suppression systems;
-   installation, operation and maintenance instructions for an explosion suppression system.
This document is applicable only to explosion suppression systems intended for the protection of closed, or essentially closed, enclosures in which an explosion could result as a consequence of ignition of an explosible mixture, e.g. dust-air, gas(vapour)-air, dust-gas(vapour)-air and mist-air.
This document is not applicable for explosions of materials listed below, or for mixtures containing some of those materials:
-   unstable materials that are liable to dissociate;
-   explosive materials;
-   pyrotechnic materials;
-   pyrophoric materials.

Determination of the spontaneous ignition behaviour of dust accumulations
SIST EN 15188:2021

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
SIST-TP CEN/TR 16829:2017+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.

Explosion resistant equipment
SIST EN 14460:2018

This European Standard specifies requirements for explosion resistant equipment which will be able to withstand an internal explosion without rupturing and will not give rise to dangerous effects to the surroundings. It is applicable to equipment (vessels and systems) where explosions are considered to be an exceptional load case.
There are two types of explosion resistant equipment: explosion pressure resistant and explosion pressure shock-resistant equipment (see Figure 1).
(...)
Explosion pressure resistant equipment is designed to withstand the explosion pressure without permanent deformation and will not give rise to dangerous effects to the surroundings. Since the design and calculation methods for explosion pressure resistant equipment are similar to those described in EN 13445-1 to -6 "Unfired pressure vessels" they are not repeated in this standard.
For explosion pressure shock resistant equipment permanent deformation is allowed provided the equipment will not give rise to dangerous effects to the surroundings. This design has been developed especially for explosion protection purposes. This standard focusses on the requirements for explosion pressure shock resistant equipment.
This standard is valid for atmospheres having absolute pressures ranging from 800 mbar to 1 100 mbar and temperatures ranging from −20 °C to +60 °C. This standard may also be helpful for the design, construction, testing and marking of equipment intended for use in atmospheres outside the validity range stated above, as far as this subject is not covered by specific standards.
This standard applies to equipment and combinations of equipment where deflagrations may occur and is not applicable to equipment and combination of equipment where detonations may occur. In this case, different design criteria for the required explosion resistance are applicable which are not covered by this standard.
It is not applicable to equipment which is designed according to type of protection, flameproof enclosures "d" (EN 13463-3 or EN 60079-1).
This standard does not apply to offshore situations.
This standard is only applicable for equipment where metallic materials provide the explosion resistance. This standard does not cover fire risk associated with the explosions, neither with the materials processed nor with the materials used for construction.
