Electrical apparatus for potentially explosive atmospheres - Electrostatic hand-held spraying equipment
This European Standard specifies the constructional and test requirements for hand-held and hand-operated electrostatic spraying equipment and associated apparatus which can be used to spray flammable liquid coating materials, flammable coating powders or flammable flock creating explosive atmosphere in spraying areas which may or may not contain flammable adhesives. This standard only deals with the hazards involved in the coating process when hand-held electrostatic spraying equipment is used as prescribed and in accordance with the conditions which are to be expected according to the manufacturer. As to other hazards involved in the use of hand-held spraying equipment, the safety requirements of EN 1953:1998 shall be met. The spraying equipment shall be constructed suitable for group II category 2 as defined in EN 60079-0
Elektrische Betriebsmittel für explosionsgefährdete Bereiche - Elektrostatische Handsprüheinrichtungen
Diese Europäische Norm legt die Bau- und Prüfbestimmungen für mit der Hand gehaltene und von der Hand geführte elektrostatische Sprühgeräte und Zubehör fest, die zum Versprühen von brennbaren flüssigen Beschichtungsstoffen, brennbaren Beschichtungspulvern oder brennbarem Flock in Sprüh bereichen verwendet werden können, die auch brennbare Kleber enthalten können oder auch nicht. Diese Norm behandelt nur die Gefahren, die für den Beschichtungsprozess kennzeichnend sind, wenn mit elektrostatischen Handsprühgeräten in der beschriebenen Art und unter Bedingungen, die der Hersteller vorgibt, gearbeitet wird. Bezüglich anderer Gefahren, die beim Gebrauch von Handsprühgeräten entstehen, müssen die Sicherheitsbestimmungen von EN 1953:1998 eingehalten werden. Die Sprühgeräte müssen so gebaut sein, dass sie Gruppe II Kategorie 2 wie in EN 60079-0 definiert entsprechen.
Appareillage électrique pour atmosphères explosibles - Equipement manuel de projection électrostatique
La présente Norme Européenne spécifie les exigences de construction et d'essais pour les matériels manuels de projection électrostatique et leur matériel associé pouvant être utilisés pour projeter de la peinture inflammable, des poudres de revêtement inflammables ou des flocks inflammables dans des emplacements de projection pouvant éventuellement contenir des adhésifs inflammables. Cette norme traite uniquement des risques encourus lors du processus de revêtement lorsque l'on utilise le matériel manuel de projection électrostatique comme prescrit et conformément aux conditions attendues selon le fabricant. Comme pour les autres risques encourus lors de l'utilisation des matériels manuels de projection, les exigences de sécurité de la EN 1953:1998 doivent être satisfaites. Les dispositifs de projection doivent être construits en étant considérés comme des matériels du groupe II catégorie 2 conformément à la EN 60079-0.

This European Standard was approved by CENELEC on 2006-05-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Cyprus, the Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,

Foreword
This European Standard was prepared by SC 31-8, Electrostatic painting and finishing equipment, of Technical
Committee CENELEC TC 31, Electrical apparatus for explosive atmospheres.
The text of the draft was submitted to the formal vote and was approved by CENELEC as EN 50050 on
2006-05-01.
This European Standard supersedes EN 50050:2001.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2007-05-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2009-05-01
This European Standard has been prepared under a mandate given to CENELEC by the European
Commission and the European Free Trade Association and covers essential requirements of EC Directive
94/9/EC. See Annex ZZ.
This European Standard specifies the constructional and test requirements for hand-held and hand-operated
electrostatic spraying and associated equipment which are used to spray flammable coating materials which
may form explosive atmospheres. These spraying equipment are considered to be equipment of group II,
category 2 in accordance with Directive 94/9/EC. It is taken for granted that the equipment will be used in
mechanically ventilated spraying areas or under equivalent ventilation conditions.
