Explosive atmospheres - Part 37: Non-electrical equipment for explosive atmospheres - Non-electrical type of protection constructional safety ''c'', control of ignition sources ''b'', liquid immersion ''k'' (ISO 80079-37:2016)

ISO 80079-37:2016 specifies the requirements for the design and construction of non-electrical equipment, intended for use in explosive atmospheres, protected by the types of protection        
constructional safety "c", control of ignition source "b" and liquid immersion "k". This part of ISO/IEC 80079 supplements and modifies the requirements in ISO 80079-36. Where a requirement of this standard conflicts with the requirement of ISO 80079-36 the requirement of this standard takes precedence. Types of protection "c", "k" and "b" are not applicable for Group I, EPL Ma without    
additional protective precautions. The types of ignition protection described in the standard can be used either on their own or in combination with each other to meet the requirements for equipment of Group I, Group II, and Group III depending on the ignition hazard assessment in ISO 80079-36.                                        
Keywords: constructional safety "c", control of ignition source "b" and liquid immersion "k"

Explosionsfähige Atmosphären - Teil 37: Nicht-elektrische Geräte für den Einsatz in explosionsfähigen Atmosphären - Schutz durch konstruktive Sicherheit 'c', Zündquellenüberwachung 'b', Flüssigkeitskapselung 'k' (ISO 80079-37:2016)

Diese Internationale Norm legt die Anforderungen an die Konstruktion und den Bau von nichtelektrischen Geräten fest, die für den Einsatz in explosionsfähigen Atmosphären vorgesehen sind und durch die Zündschutzarten konstruktive Sicherheit "ch", Zündquellenüberwachung "bh" und Flüssigkeitskapselung "kh" geschützt sind.
Die Norm ergänzt und modifiziert die Anforderungen in ISO 80079-36. Wenn eine Anforderung dieser Norm im Widerspruch zu der Anforderung von ISO 80079-36 steht, hat die Anforderung der vorliegenden Norm Vorrang.
Die Schutzarten "ch", "kh" und "bh" sind ohne zusätzliche Schutzmaßnahmen für Gruppe I, EPL Ma, nicht anwendbar.
Die in der Norm beschriebenen Zündschutzarten können entweder für sich allein oder in Kombination miteinander angewendet werden, um die Anforderungen an Geräte der Gruppe I, Gruppe II und Gruppe III in Abhängigkeit von der Zündgefahrenbewertung in ISO 80079-36 zu erfüllen.

Atmosphères explosives - Partie 37: Appareils non électriques destinés à être utilisés en atmosphères explosives - Mode de protection non électrique par sécurité de construction "c", par contrôle de la source d'inflammation "b", par immersion dans un liquide "k" (ISO 80079-37:2016)

L'ISO 80079-37:2016 spécifie les exigences relatives à la conception et à la construction d'un appareil non électrique, destiné à être utilisé dans les atmosphères explosives et protégés par les modes de protection par sécurité de construction "c", par contrôle de la source d'inflammation "b", par immersion dans un liquide "k". La présente partie de l'ISO/IEC 80079 complète et modifie les exigences de l'ISO 80079-36. Lorsqu'une exigence de cette norme s'oppose à une exigence de l'IEC 80079-36, l'exigence de cette norme prime. Les types de protections "c", "k" et "b" ne s'appliquent pas pour le Groupe I, EPL Ma sans l'ajout d'autres précautions de protection. Les modes de protection contre l'inflammation décrits dans la norme peuvent être utilisés indépendamment ou en combinaison les uns avec les autres pour satisfaire aux exigences relatives aux appareils du Groupe I, du Groupe II et du Groupe III, en fonction de l'évaluation du danger d'inflammation dans l'ISO 80079-36.                      
Mots clés: sécurité de construction "c", par contrôle de la source d'inflammation "b", par immersion dans un liquide "k"

Eksplozivne atmosfere - 37. del: Neelektrična oprema za uporabo v potencialno eksplozivnih atmosferah - Neelektrična vrsta zaščite s konstrukcijsko varnostjo "c", kontrolo virov vžiga "b", s potopitvijo v tekočino "k" (ISO 80079-37:2016)

Ta mednarodni standard določa zahteve za načrtovanje in konstrukcijo neelektrične opreme, ki je namenjena za uporabo v eksplozivnih atmosferah in je zaščitena z vrstami zaščite s konstrukcijsko varnostjo, kontrolo virov vžiga in potopitvijo v tekočino.
Ta standard dopolnjuje zahteve iz standarda IEC 80079-36, katerega vsebina se prav tako v celoti uporablja za opremo, izdelano v skladu s tem standardom.

NOTE 1 The technical changes referred include the significant technical changes from the EN revised but is not
an exhaustive list of all modifications from the previous version.
Explanations:
A) Definitions
Minor and editorial changes clarification
decrease of technical requirements
minor technical change
editorial corrections
Changes in a standard classified as ‘Minor and editorial changes’ refer to changes regarding the
previous standard, which modify requirements in an editorial or a minor technical way. Also changes of
the wording to clarify technical requirements without any technical change are classified as ‘Minor and
editorial changes’.
A reduction in level of existing requirement is also classified as ‘Minor and editorial changes’
Extension addition of technical options

Changes in a standard classified as ‘extension’ refers to changes regarding the previous standard, which
add new or modify existing technical requirements, in a way that new options are given, but without
increasing requirements for equipment that was fully compliant with the previous standard. Therefore
these ‘extensions’ will not have to be considered for products in conformity with the preceding edition.
Major technical changes addition of technical requirements
increase of technical requirements

Changes in a standard classified as ‘Major technical change’ refer to changes regarding the previous
standard, which add new or increase the level of existing technical requirements, in a way that a
product in conformity with the preceding standard will not always be able to fulfil the requirements
given in the standard. ‘Major technical changes’ have to be considered for products in conformity with
the preceding edition. For every change classified as ‘Major Technical Change’ additional information is
provided in clause B) of the Annex ZB.
NOTE 2 These changes represent current technological knowledge . However, these changes should not
normally have an influence on equipment already placed on the market.
B) Information about the background of ‘Major Technical Changes’
