Bibliography

This European Standard specifies the significant hazards of machines for surface cleaning and pre-treatment - in the following called "cleaning machines" - of industrial items using halogenated solvents, either pure or as a mixture.This European Standard applies together with EN 12921-1:2005. Both parts together cover all significant hazards relevant for cleaning machines of industrial items using liquids or vapours, when they are used as intended and under the conditions foreseen by the manufacturer (see Clause 4). The specific requirements specified in Part 4 take precedence over the respective requirements in EN 12921-1:2005.This European Standard applies together with EN 12921-3 in case of release of flammable vapours from the cleaning liquids.This European Standard does not apply to machinery and related equipment excluded from the scope of EN 12921-1:2005.This European Standard is not applicable to cleaning machines which are manufactured before the publication of this European Standard by CEN.
