1.1 This standardapplies to machines for surface cleaning and pre-treatment - in the following called
"cleaning machines" - of industrial items using liquids or vapours, i. e. stationary machines and related
equipment for automated and manual cleaning and pre-treatment processes.
NOTE Cleaning machines are operated with or without heating, for example as dipping or spraying or vapour
condensation process, where additional using of ultrasound is possible. These cleaning machines could be designed
as single-zone or multi-zone machine, chamber machines, drum cleaning machine, low lift truck machines, round
time machines or tunnel (continuous) machines.
To the extent of this document, cleaning machines for industrial items are considered as an assembly of the
following equipment:
pump(s) and/or other mechanical system of agitation, recirculation and spraying of cleaning liquid;
forced ventilation system;
heating system with temperature control;
condensation system;
filtration and separation system and/or solid particles extraction from the liquid;
conveyor and/or handling system for the items to be processed;
product handling systems and reciprocators which are part of the cleaning machine;
control and/or monitoring systems;
liquid handling system.
1.2 This European Standard deals with the common significant hazards, hazardous situations and events
relevant to cleaning machines for industrial items using liquids or vapours when they are used as intended
and under the conditions foreseen by the manufacturer (see clause 4). This part of the standard defines the
common safety requirements for all kinds of cleaning machines for industrial items using liquids or vapours
and related common devices and should be used in connection with other parts of the EN 12921-series. The
specific requirements specified in part 2 and following parts of EN 12921 take precedence over the respective
requirements in EN 12921.
NOTE In addition, where a cleaning machine is not covered by a specific part of this document, part 1 of EN
12921 can be used to establish the approach for dealing with the relevant risks.
Specific hazards which are related to the type of cleaning liquid used are dealt with in the following
documents:
EN 12921-2 for water based cleaning liquids;
EN 12921-3 for flammable cleaning liquids;
prEN 12921-4 for halogenated solvents.
1.3 This standard is not applicable to:
mobile portable cleaning;
EN 12921-1:2005 (E)

centrifuges as covered by EN 12547;
pumps and pump units for liquids as covered by EN 809;
plasma energy;
mechanical blasting;
heat and/or thermal energy;
hazards related to drying processes;
cleaning of textiles or clothes;
food processing.
1.4 This standard is not applicable to cleaning machines for industrial items which are manufactured before
the date of publication of this document by CEN.
Diese Europäische Norm gilt für Maschinen zur Oberflächenreinigung und -vorbehandlung - im Folgenden "Reinigungsanlagen" genannt - von industriellen Produkten, in denen Flüssigkeiten oder Dampfphasen verwendet werden, d. h. ortsfeste Anlagen und zugehörige Ausrüstung für automatisierte und manuelle Reinigungs- und Vorbehandlungsverfahren. Dieser Teil der Norm legt die allgemeinen Sicherheitsanforderungen für alle Arten von Reinigungsmaschinen für industrielle Produkte fest, in denen Flüssigkeiten oder Dampfphasen verwendet werden, sowie für dazugehörige Einrichtungen und muss in Verbindung mit den anderen Teilen der EN 12921-Reihe verwendet werden.
