Non-electrical equipment for potentially explosive atmospheres - Part 8: Protection by liquid immersion 'k'
1.1 This European Standard specifies the requirements for the design, construction, testing and marking of ignition protected equipment using liquid immersion 'k' as a means of preventing potential ignition sources from becoming effective according to the category, or categories, of the equipment to which it is constructed.
1.2 It may be used to provide ignition protection, either as an independent means, in addition to, or in combination with, other types of ignition protection listed in prEN 13463-1 for Group I, categories M1 and M2 and Group II, categories 1G, 1D, 2G, 2D, 3G and 3D equipment, according to the ignition hazard assessment.
1.3 This European Standard supplements the requirements of prEN 13463-1 insofar as it applies to the protection of non-electrical equipment by liquid immersion 'k'.
1.4 This European Standard does not apply to the ignition protection of electrical equipment. For these requirements reference shall be made to EN 50014 and EN 50015, which inter-alia, requires electrically non-conducting protective liquids to be used.
Nicht-elektrische Geräte für den Einsatz in explosionsgefährdeten Bereichen - Teil 8: Schutz durch Flüssigkeitskapselung 'k'
1.1 Diese Europäische Norm legt die Anforderungen an Konstruktion, Bau, Prüfung und Kennzeichnung von Geräten mit der Zündschutzart Flüssigkeitskapselung ,k' als Maßnahme gegen das Wirksamwerden von potenziellen Zündquellen entsprechend der Kategorie oder den Kategorien des Geräts fest, für die es gebaut ist.
1.2 Sie kann verwendet werden, um einen Zündschutz entweder als unabhängige Maßnahme zusätzlich zu oder in Kombination mit anderen Zündschutzarten nach EN 13463-1 für Geräte der Gruppe I der Kategorien M1 und M2 und der Gruppe II, Kategorien 1G, 1D, 2G, 2D, 3G und 3D entsprechend der Bewertung der Zündgefahr vorzusehen.
1.3 Diese Europäische Norm ergänzt die Anforderungen von EN 13463-1 insofern, als sie für den Schutz durch Flüssigkeitskapselung ,k' von nicht-elektrischen Geräten gilt.
1.4 Diese Europäische Norm gilt nicht für den Zündschutz von elektrischen Geräten. Für diese Anforderungen sollte auf EN 50014 und EN 50015 verwiesen werden, die unter anderem den Einsatz nichtleitender Schutzflüssigkeiten fordern.
Appareils non électriques destinés à être utilisés en atmosphères explosibles - Partie 8: Protection par immersion dans un liquide 'k'
1.1 La présente Norme européenne spécifie les exigences de conception, de construction, d'essai et de marquage des appareils protégés contre l'inflammation par immersion dans un liquide 'k', utilisé comme moyen pour empêcher les sources potentielles d'inflammation de devenir actives conformément à la catégorie ou aux catégories d'appareil selon laquelle/lesquelles il est construit.
1.2 Ce moyen peut être utilisé pour procurer une protection contre l'inflammation soit indépendamment, soit en complément ou en combinaison avec d'autres modes de protection contre l'inflammation énumérés dans l'EN 13463-1 pour les appareils du groupe I, catégories M1 et M2, et du groupe II, catégories 1G, 1D, 2G, 2D, 3G et 3D, conformément à l'évaluation du risque d'inflammation.
1.3 La présente Norme européenne complète les exigences de l'EN 13463-1 en ce sens qu'elle s'applique à la protection des appareils non électriques par immersion dans un liquide 'k'.
1.4 La présente Norme européenne ne s'applique pas à la protection contre l'inflammation des appareils électriques. Pour ces exigences, il convient de se référer à l'EN 50014 et à l'EN 50015 qui requièrent, entre autres, l'utilisation de liquides de protection non conducteurs de l'électricité.

Up-to-date lists and bibliographical references concerning such nationalstandards may be obtained on application to the Management Centre or to any CEN member.This European Standard exists in three official versions (English, French, German). A version in any other language made by translationunder the responsibility of a CEN member into its own language and notified to the Management Centre has the same status as the officialversions.CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and UnitedKingdom.EUROPEAN COMMITTEE FOR STANDARDIZATIONCOMITÉ EUROPÉEN DE NORMALISATIONEUROPÄISCHES KOMITEE FÜR NORMUNGManagement Centre: rue de Stassart, 36

movingmechanisms immersed below the lowest allowable level of the flammable liquid being processed (e.g.petroleum product dispensers),c) hydraulic pumps and motors having their internal rotating parts continuously immersed in the flowing hydraulicfluid used to transmit the hydrostatic or hydrokinetic energy,d) oil filled gearboxes, having their gear wheels partially immersed, but continuously coated by a viscous film oflubricating oil. In this example the protective oil coating may be supplied by natural splashing of the wheels asthey rotate in the oil, or by directing a continuously flowing stream of oil directly onto them from an oil pump inthe gearbox sump,e) fluid couplings, torque converters, connected for example, between the output shaft of a driving motor and theinput shaft of fully loaded machine, to allow it to be started gradually (‘soft starting’).In all of the above, ignition protection is achieved by the fact that protective liquid prevents the surroundingexplosive atmosphere from coming into contact with the ignition source(s) by continuously coating, and/orlubricating and cooling the moving parts.A similar type of ignition protection, known as oil immersion ”o”, has been used for many years for electricalequipment, where, in addition to the above, the liquid also acts as an electrical insulating medium. It is for this latterreason that this standard cannot be applied to electrical equipment, because it allows the use of liquids thatconduct electricity.
