Explosion resistant equipment

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.

Explosionsfeste Geräte

Diese Europäische Norm legt die Anforderungen an explosionsfeste Geräte fest, die einer im Innern erfolgenden Explosion standhalten werden, ohne zu bersten und ohne gefährliche Auswirkungen auf die Umgebung hervorzurufen. Sie ist auf Geräte (Behälter und Systeme) anwendbar, bei denen Explosionen eine außergewöhnliche Belastung darstellen.
Es gibt zwei Arten explosionsfester Geräte: explosionsdruckfeste und explosionsdruckstoßfeste Geräte (siehe Bild 1).
Explosionsdruckfeste Geräte sind so gebaut, dass sie dem Explosionsdruck standhalten, ohne sich bleibend zu verformen und ohne gefährliche Auswirkungen auf die Umgebung hervorzurufen. Da die Auslegungs- und Berechnungsverfahren explosionsdruckfester Geräte den in EN 13445 Teil 1 bis 6 "Unbefeuerte Druckbehälter" beschriebenen ähnlich sind, werden sie in dieser Norm nicht erneut aufgeführt.
Bei explosionsdruckstoßfesten Geräten ist eine dauerhafte Verformung zulässig, sofern diese Geräte keine gefährlichen Auswirkungen auf die Umgebung hervorrufen. Diese Bauweise wurde speziell für Explosionsschutzzwecke entwickelt. Diese Norm stellt die Anforderungen an explosionsdruckstoßfeste Geräte in den Mittelpunkt.
Diese Norm gilt für Atmosphären mit Absolutdrücken im Bereich von 800 mbar bis 1 100 mbar und Temperaturen im Bereich von −20 °C bis +60 °C. Diese Norm kann auch für die Auslegung, Konstruktion, Prüfung und Kennzeichnung von Geräten von Nutzen sein, die für Atmosphären außerhalb des oben festgelegten Anwendungsbereiches vorgesehen sind, sofern dieses Thema nicht durch spezifische Normen abgedeckt ist.
Diese Norm ist auf Geräte und Gerätekombinationen anwendbar, in denen sich Deflagrationen ereignen können. Sie ist nicht auf Geräte und Gerätekombinationen anwendbar, in denen Detonationen vorkommen können. In solchen Fällen sind für die erforderliche Explosionsfestigkeit andere Auslegungskriterien anwendbar, die in dieser Norm nicht behandelt werden.
Sie ist nicht anwendbar auf Geräte, die nach der Zündschutzart "Druckfeste Kapselung" "d" (EN 13463-3 oder EN 60079-1) konstruiert sind.
Diese Norm gilt nicht für Offshore-Anwendungen.
Diese Norm ist nur auf Geräte anwendbar, deren Explosionsfestigkeit durch die Verwendung metallischer Werkstoffe erreicht wird. Diese Norm behandelt nicht die mit den Explosionen einhergehende Brandgefahr, weder bezüglich der verarbeiteten noch der für die Konstruktion verwendeten Werkstoffe.

Appareil résistant à l'explosion

La présente Norme européenne spécifie les exigences applicables aux appareils résistants à l'explosion qui devront supporter une explosion intérieure sans rompre et sans engendrer d'effets dangereux pour le milieu environnant. Elle s'applique aux appareils (enceintes et systèmes) dans lesquels les explosions sont considérées comme un cas de charge accidentelle.
Il existe deux types d'appareils résistants à l'explosion : les appareils résistants à la pression d'explosion et les appareils résistants au choc de pression de l'explosion (voir Figure 1).
Un appareil résistant à la pression d'explosion est conçu pour supporter la pression d'explosion sans déformation permanente et sans engendrer d'effets dangereux pour le milieu environnant. La conception et les méthodes de calcul des appareils résistants à la pression d'explosion étant similaires à celles décrites dans l'EN 13445-1 à -6, « Récipients sous pression non soumis à la flamme », elles ne sont pas reprises dans la présente norme.
Pour les appareils résistants au choc de pression de l'explosion, une déformation permanente est admise à condition que l'appareil n'engendre pas d'effets dangereux pour le milieu environnant. Cette conception a été développée spécialement à des fins de protection contre l'explosion. La présente norme est axée sur les exigences applicables aux appareils résistants au choc de pression de l'explosion.
La présente norme concerne les atmosphères dont la pression absolue est comprise entre 800 mbar et 1 100 mbar et la température entre −20 °C et + 60 °C. Il est possible de s’aider de la présente norme lors de la conception, de la construction, des essais et du marquage d’appareils destinés à être utilisés dans des atmosphères dont les caractéristiques sont différentes de celles citées ci-dessus et ce, tant que le sujet ne fait pas l’objet de normes spécifiques.
La présente norme s’applique aux appareils et combinaisons d’appareils dans lesquels peut se produire une déflagration et n’est pas applicable aux appareils et combinaisons d’appareils dans lesquels peuvent se produire des détonations. Dans ce cas, des critères de conception différents, non traités dans la présente norme, sont applicables pour la résistance à l'explosion requise.
Elle ne s’applique pas aux appareils conçus selon un type de protection par enveloppe antidéflagrante « d » (EN 13463 -3 ou EN 60079 -1).
La présente norme ne s'applique pas aux situations en mer (offshore).
La présente norme s’applique uniquement aux appareils dans lesquels des matériaux métalliques assurent la résistance à l’explosion. La présente norme ne traite pas du risque d'incendie associé aux explosions, aux matériaux traités ou aux matériaux utilisés pour la construction.

Overview

EN 14460:2018 is a CEN European Standard that specifies requirements for explosion resistant equipment (vessels and systems) intended to withstand internal explosions without rupturing or creating dangerous effects to the surroundings. The standard distinguishes two classes of equipment:

  • Explosion pressure resistant (no permanent deformation; design methods align with EN 13445 series for unfired pressure vessels)
  • Explosion pressure shock resistant (permanent deformation allowed provided hazards to surroundings are avoided) - the primary focus of EN 14460:2018.

The standard covers atmospheres at absolute pressures from 800 mbar to 1 100 mbar and temperatures from −20 °C to +60 °C, applies to deflagrations (not detonations), and is limited to equipment using metallic materials for explosion resistance. Offshore applications and flameproof enclosures “d” (EN 13463‑3 / EN 60079‑1) are excluded.

Key Topics

  • Design concepts for explosion pressure shock resistant equipment, including permissible stresses and weld seam factors.
  • Design pressure and temperature considerations and additional loads relevant to explosion scenarios.
  • Material selection criteria for ductile and brittle metallic materials suitable for shock-resistant designs.
  • Testing and verification: type testing, pressure tests and explosion tests; documentation of test results.
  • Finite Element Analysis (FEA): normative guidance (Annex C) for using FEA in design, including software validation and model documentation.
  • Quality assurance and documentation: material traceability (EN 10204), NDT (EN 13018), welding quality, and manufacturing quality systems (EN ISO/IEC 80079‑34).
  • Operational information and marking requirements and guidance on venting, suppression and pipe/interconnected vessel behavior (Annex B).

Applications

EN 14460:2018 is used by:

  • Manufacturers and designers of pressure vessels, process equipment and industrial enclosures where deflagrations are a possible but exceptional load case.
  • Safety and process engineers defining explosion protection strategies (design for maximum pressure or reduced pressure with venting/suppression).
  • Test houses and certification bodies conducting pressure and explosion tests, and reviewing FEA or engineering design documentation. Practical sectors include industries handling flammable gases, vapours or combustible dusts (where deflagrations-not detonations-are the hazard). The standard helps ensure equipment maintains structural integrity or limits hazardous effects during an unexpected explosion.

Related Standards

  • EN 13445‑1 to ‑6 (Unfired pressure vessels) - referenced for pressure‑resistant design methods
  • EN 13237 (terms/definitions for explosive atmospheres)
  • EN 10204, EN 13018, EN ISO 6892‑1, EN ISO 9712, EN ISO/IEC 80079‑34 - referenced normative documents
  • EN 13463‑3 / EN 60079‑1 - flameproof enclosure standards (not covered by EN 14460)

EN 14460:2018 is essential for compliant explosion protection design where metallic construction provides the required resistance and deflagration scenarios are assessed.

Figure 1 — Explosion resistant equipment 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
« t r °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. SIST EN 14460:2018

design for the maximum explosion pressure; SIST EN 14460:2018

design for the reduced explosion pressure in combination with explosion venting or explosion suppression. NOTE If explosions are part of the normal operation (allowed operation pressure) the design rules of this standard do not apply. 4.2 Design procedure The procedure for explosion pressure shock resistant design is as follows: — define geometry; — define design pressure, temperature and loads (see 4.3, 4.4, 4.5); — choose materials (see Clause 5); — define safety factors for material properties (see 6.2.1); — calculate according to state of the art with engineering standards or finite element methods or prove design by testing. NOTE See additional information in Bibliography. 4.3 Design pressure The design pressure shall not be less than the maximum gauge pressure occurring in the equipment, when subjected to explosion or reduced explosion conditions. If the inside of the equipment is divided into sections (e.g. vessels connected by pipes or containing baffles or surge plates) and an explosion is initiated in one of the sections the pressure in the other sections of the equipment will be increased. As a result, an explosion in these sections will occur at an elevated initial pressure and/or a higher turbulence level. Explosion pressures will thus be higher than the value expected under atmospheric conditions. In the case of such arrangements, appropriate measures shall be taken, either explosion isolation techniques or explosion resistant design derived from representative explosion tests or validated explosion modelling (see informative Annex B). NOTE 1 Pressures quoted are gauge pressures unless otherwise stated. NOTE 2 If an explosion is initiated at pressures higher than atmospheric pressure, the maximum explosion pressure will rise proportionally to the initial pressure. NOTE 3 For guidance on the derivation of design pressure for single vessels see Annex A, for interconnected vessels and pipes see Annex B. For explosion venting, the design pressure is derived from EN 14491 and EN 14994 for dust and gas explosions respectively. For explosion suppression, the design pressure is given by the manufacturer of the explosion suppression system according to EN 14373. 4.4 Design temperature In case of an explosion the vessel walls will generally not heat up significantly. Therefore, the intended operating temperatures (minimum and maximum) at the initial pressure shall be used as the design temperatures. The effect of higher gas temperatures caused by exothermic reactions (e.g. subsequent fire) should be considered for gaskets and bolts. Depending on the dimensions of the equipment fully contained light-metal dust explosions could give rise to elevated wall temperatures which should be assessed. SIST EN 14460:2018

· 27 J, ISO V-notch. The test temperature shall not be higher than the lowest intended operating temperature and shall not exceed 20 °C. NOTE 2 For further information on ISO V-notch see EN ISO 148-1. The term “steel” covers e.g. ferrite, austenitic and cast steel. The material properties of these shall be assessed against the given criteria for ductility. b) aluminium with SIST EN 14460:2018

· 20 %, test temperature 20 °C; and 2) notch impact energy not relevant. 5.3 Criteria for brittle materials For materials not fulfilling the criteria of 5.2 the design stresses for brittle materials in 6.2.1 shall be used. NOTE Typical brittle materials are flake graphite castings, cast aluminium G-Al Mg 5 and G-Al Si Mg wa. For testing, brittle materials may be subdivided into two groups: — materials with high notch impact energy: Materials with minimum notch impact energy of 14 J (mean value of three tests), single values shall not be less than 11 J; — materials with low notch impact energy: Materials not fulfilling notch impact energy criteria. 6 Explosion pressure shock resistant design 6.1 General Explosion pressure shock resistant equipment shall be designed such that it can withstand the maximum or reduced explosion pressure without rupturing, but may become permanently deformed [see 8.2 i)]. Explosion pressure shock resistant equipment shall be designed or tested either by a) design according to 6.2, documentation of quality according to 7.2, 7.3 and 7.4 for each item, or b) pressure or explosion test as a type test according to 6.3, documentation of quality according to 7.2, 7.3 and 7.4 for each item. 6.2 Design 6.2.1 Definition of permissible stresses NOTE 1 During short durational loading, the yield stress of metals increases, but the ultimate strength is hardly effected. The actual increase in yield stress depends on the strain rate (1/s) and the characteristics of the metal involved. For explosion pressure resistant design the strain rate is typically in the order of 10 «4 – 10 «2 1/s. For carbon steel only a minor increase in yield stress will arise at such loading rates ((0 – 15) %). However, the duration of the loading is rather long (typically 0,1 s – > 1 s) and the increase in yield stress will be even lower. As a consequence, for explosion protection, it is a correct and safe approach to apply the normal yield stress. It is possible to use verification by engineering rules or finite element methods. NOTE 2 See Bibliography for further references. Detailed design features which can lead to cracking shall be avoided. This requires limitation of stress concentrations (for examples see Annex E). If design is done according to technical standards (membrane or two-dimensional stress), the permissible stresses are as follows: Ductile ferritic material ()ϑ=021,/dfpfR Ductile austenitic material ()ϑ=21%/dafR SIST EN 14460:2018

F Ductile materials according to 5.2 1,1 Brittle materials with high notch impact energy according to 5.3 1,3 Brittle materials with low notch impact energy according to 5.3 2,0 6.4 Special requirements for bolted structures Explosion pressure shock resistant equipment consisting of bolted structures shall withstand the explosion pressure with or without permanent deformation and shall not give rise to dangerous effects to the surroundings. Flame ejection, excessive emission of pressure and/or hot gases/dust during the explosion through gaps between construction elements to the surroundings shall be considered as a dangerous effect. The design and test procedure including test criteria for bolted structures shall address this point. Gaskets or seals which are designed to prevent the dangerous effects shall be part of the design procedure, type and routine tests. If bolted structures are solely designed by Finite Element Analysis and are not covered by other technical standards the assessment of the consequences of deformations shall be based on experimental validation of prototypes with geometrical similarity. 6.5 Docu

La norme EN 14460:2018 se concentre sur les exigences relatives à l'équipement résistant aux explosions, garantissant sa capacité à supporter une explosion interne sans rupture et à ne pas induire d'effets dangereux pour les environs. Son champ d'application est clairement défini, se limitant aux équipements tels que les récipients et systèmes exposés à des cas de charge exceptionnelle liés aux explosions. Parmi ses points forts, la norme distingue deux types d'équipement : l'équipement résistant à la pression d'explosion et l'équipement résistant aux chocs de pression d'explosion. La conception et les méthodes de calcul pour l'équipement résistant à la pression d'explosion suivent des principes bien établis, similaires à ceux détaillés dans la norme EN 13445-1 à -6 sur les récipients sous pression non chauffés. Cela permet une cohérence dans la compréhension et l'application des exigences de conception adaptées, tout en évitant la redondance. De plus, la norme permet une déformation permanente pour l'équipement résistant aux chocs de pression d'explosion, tant que cela ne cause pas d'effets dangereux. Cela est particulièrement important pour le développement de solutions de protection contre les explosions, favorisant une flexibilité dans la conception pour des applications spécifiques. La norme est également pertinente pour une large gamme d'atmosphères, spécifiant des pressions absolues allant de 800 mbar à 1 100 mbar et des températures comprises entre -20 °C et +60 °C. L'élargissement de son utilité à des équipements en dehors de cette plage de validité, tant que les autres normes spécifiques ne s'appliquent pas, témoigne de sa robustesse et de sa pertinence. Cependant, il est important de noter que cette norme ne s'applique pas aux détonations, qui requièrent des critères de conception différents pour garantir la résistance aux explosions, ni aux situations offshore. En outre, elle exclut les dispositifs conçus selon le type de protection de type "d" (enclosures à épreuve de flamme), ce qui souligne son application spécifique aux matériaux métalliques. En résumé, la norme EN 14460:2018 joue un rôle crucial dans la sécurité des équipements destinés à résister à des conditions d'explosion, en offrant des directives claires et précises pour la conception, la construction, et l'utilisation en toute sécurité de tels équipements. Sa spécificité renforce sa pertinence dans le domaine de la sécurité industrielle, faisant de cette norme un standard incontournable pour les professionnels du secteur.

EN 14460:2018は、爆発に対する耐性を持つ機器に関する非常に重要な欧州標準です。この標準では、内部爆発に耐えることができる設備(容器やシステム)についての要求事項が定められています。爆発が異常負荷と見なされる設備に適用され、周囲に危険な影響を与えないことが求められます。 この標準には、爆発圧耐性機器と爆発圧衝撃耐性機器の2種類があり、いずれも特定の設計と計算方法を基にしています。特に、爆発圧衝撃耐性機器は、周囲に危険な影響を与えない限り、永久変形が許可されています。このような設計は爆発保護の目的に特化して開発されており、本標準はこの設計に対する要求に焦点を当てています。 標準の適用範囲は絶対圧800 mbarから1,100 mbar、温度範囲は−20°Cから+60°Cまでの大気に有効です。これにより、特定の基準でカバーされていない範囲外の大気で使用される機器の設計、施工、試験およびマーキングに関しても役立つ可能性があります。ただし、爆発が発生する可能性のある設備やその組み合わせにのみ適用され、爆轟が発生する可能性のある設備には適用されません。 また、この標準は、保護の種類に基づく設計、特に耐火エンクロージャ「d」(EN 13463-3またはEN 60079-1)に従って設計された機器には適用されません。また、オフショア状況にも適用されません。金属材料が爆発耐性を提供する機器のみに限定されており、爆発に関連する火災リスクや、処理される材料及び構造に使用される材料に関しては本標準はカバーしていません。 このように、EN 14460:2018は爆発に対する強固な耐性を提供するための重要なベースラインを提供し、特に爆発圧衝撃耐性機器の要求事項に関する指針を描くものであり、産業界における安全性を高めるための信頼性の高い基準となっています。

The EN 14460:2018 standard provides a comprehensive framework for the design and construction of explosion resistant equipment, ensuring that such equipment can safely withstand internal explosions. Its primary scope is to establish requirements that not only protect the integrity of the equipment but also safeguard the surroundings from the dangerous effects of these explosions. One of the significant strengths of this standard lies in its clear distinction between two types of explosion resistant equipment: explosion pressure resistant and explosion pressure shock-resistant. This classification allows for targeted design approaches, with the standard offering specific guidelines that enable engineers and manufacturers to determine the appropriate design methods based on the nature of the expected explosion. The inclusion of accepted calculation methodologies, based on established norms from EN 13445-1 to -6 for unfired pressure vessels, while not repeating those details, provides a well-structured approach for professionals familiar with these existing standards. The standard's relevance extends beyond merely the outlined requirements; it addresses atmospheres with defined pressures and temperatures, providing a supportive guideline for scenarios that may fall outside these specifications. This adaptability enhances the standard's application across various contexts where explosion resistance is vital, showcasing its broader applicability in designing, constructing, testing, and marking equipment not expressly covered by specific additional guidelines. However, potential users should note the limitations of the standard, specifying that it does not apply to situations where detonations occur or where flameproof enclosures are involved. This specificity ensures the standard remains focused and relevant to its intended application, enhancing safety in environments where deflagrations are considered the norm. Moreover, by concentrating solely on equipment made from metallic materials, this standard harnesses the known properties of such materials in explosion resistance, thereby solidifying its position in the market for safety engineering. Its exclusion of fire risks associated with explosions underlines the need for complementary standards when addressing broader safety parameters. Overall, EN 14460:2018 stands as a critical tool for stakeholders in the design and implementation of explosion resistant equipment, reflecting the latest in safety standards while remaining specific enough to guide accurately without overextending its scope.

Die Norm EN 14460:2018 legt umfassende Anforderungen für explosionsgeschütztes Equipment fest, welches in der Lage ist, interne Explosionen zu widerstehen, ohne dabei zu zerbrechen oder gefährliche Auswirkungen auf die Umgebung zu verursachen. Dadurch wird insbesondere der Schutz von Mitarbeitern und Infrastruktur in Umgebungen, in denen Explosionen als außergewöhnliche Last betrachtet werden, sichergestellt. Die Norm differenziert zwischen zwei Typen von explosionsgeschütztem Equipment: explosionsdruckbeständigen und explosionsdruckschockbeständigen Geräten. Der klare Fokus auf diesen beiden Ausstattungsarten stärkt die Relevanz der Norm im Bereich der Sicherheitstechnik, da sie spezifische Anforderungen für beide Kategorien definiert. Die explosionsdruckbeständigen Geräte sind so konstruiert, dass sie den Explosionsdruck ohne dauerhafte Verformung widerstehen, während bei explosionsdruckschockbeständigen Geräten eine permanente Verformung toleriert wird, solange keine gefährlichen Auswirkungen auf die Umgebung eintreten. Dies zeigt die Flexibilität der Norm und die Berücksichtigung unterschiedlicher Maßnahmen für den Explosionsschutz. Ein weiterer wichtiger Aspekt ist der festgelegte Anwendungsbereich, der für Atmosphären mit absoluten Druckbereichen von 800 mbar bis 1.100 mbar sowie Temperaturen von −20 °C bis +60 °C gilt. Diese Festlegung bietet eine klare Leitlinie für die Entwicklung und den Bau von Geräten und Systemen in diesen Umweltbedingungen. Zudem stellt die Norm eine wertvolle Grundlage für die Konstruktion, Prüfung und Kennzeichnung von Geräten dar, die in Atmosphären außerhalb des Geltungsbereichs vorgesehen sind, sofern dies nicht durch spezifische Normen abgedeckt ist. Die EN 14460:2018 ist nicht zutreffend für Systeme, in denen Detonationen auftreten können, und sie ist auch nicht auf Einrichtungen anwendbar, die gemäß dem Typenschutz „flammenhemmende Gehäuse“ konstruiert sind. Dieser Ausschluss schützt vor Missverständnissen und lenkt die Norm auf die speziell behandelten Sicherheitsfragen, was ihre Aussagekraft und Anwendbarkeit im relevanten Bereich unterstreicht. Zusammengefasst bietet die EN 14460:2018 einen klaren, präzisen und praxisnahen Rahmen für explosionsgeschütztes Equipment, der sowohl die Sicherheitsanforderungen berücksichtigt als auch den spezifischen Herausforderungen im Bereich von Deflagrationen Rechnung trägt. Die Norm ist somit unverzichtbar für Ingenieure und alle Fachleute, die an der Gestaltung und dem Betrieb solcher sicherheitskritischen Systeme beteiligt sind.

EN 14460:2018 표준은 폭발 저항 장비에 대한 요구 사항을 명확히 규정하고 있습니다. 이 표준은 내부 폭발을 견딜 수 있는 장비가 파열되는 것을 방지하고, 주변에 위험한 영향을 미치지 않도록 설계되었습니다. 특히 폭발이 비정상적인 하중으로 간주되는 장비(용기 및 시스템)에 적용됩니다. 이 표준의 강점 중 하나는 폭발 저항 장비의 두 가지 유형을 명확히 한 점입니다. 폭발 압력 저항 장비는 영구 변형 없이 폭발 압력을 견딜 수 있도록 설계되었으며, 주변에 위험한 영향을 미치지 않도록 보장합니다. 이러한 설계와 계산 방법은 EN 13445-1부터 -6까지의 "비가열 압력 용기"와 유사하여 이를 반복하지 않고도 정의합니다. 또한, 폭발 압력 충격 저항 장비에 대해서는 영구 변형이 허용되지만, 이 장비 역시 주변에 위험한 영향을 미치지 않아야 합니다. 이 표준은 특히 폭발 방지 목적을 위해 개발되었으며, 폭발 압력 충격 저항 장비에 대한 요구 사항에 중점을 두고 있습니다. 또한, 이 표준은 절대 압력이 800 mbar에서 1,100 mbar까지, 온도는 -20 °C에서 +60 °C까지의 대기로 유효합니다. 이 범위를 벗어나는 대기에 사용될 장비의 설계, 건설, 시험 및 표시와 관련하여 특정 표준으로 다루어지지 않는 한 도움이 될 수 있습니다. EN 14460:2018은 분진 화재와 폭발이 발생할 수 있는 장비 및 장비 조합에 적용되며, 폭발이 발생할 수도 있는 장비나 조합에는 적용되지 않습니다. 이 경우 요구되는 폭발 저항을 위한 다른 설계 기준이 적용되며, 이 표준에서는 다루어지지 않습니다. 또한, "d" 타입의 불꽃 방지 인클로저(EN 13463-3 또는 EN 60079-1)로 설계된 장비에는 적용되지 않으며, 해상 상황에도 적용되지 않습니다. 마지막으로, 이 표준은 금속 재료가 폭발 저항을 제공하는 장비에만 적용되며, 폭발과 관련된 화재 위험이나 사용되는 재료에 대한 내용은 포함되지 않습니다. 이러한 특성들은 EN 14460:2018이 산업 현장에서의 안전성 및 규정 준수에 있어 얼마나 중요한지를 잘 보여줍니다.
