本欧洲标准规定了使用纯的或作为混合物使用卤化溶剂的工业物品在表面清洁和预处理（以下称为“清洁机器”）中的重大危害。 本欧洲标准适用于EN 12921-1:2005。这两个部分一起使用液体或蒸气的工业物品的清洁机器，在制造商预期使用的条件下（见第4条），可以涵盖与清洁机相关的所有重大危险。第4部分中规定的具体要求优先于EN 12921-1:2005中各自的要求。 本欧洲标准与EN 12921-3一起适用于清洁液体释放易燃蒸气的情况。 本欧洲标准不适用于不在EN 12921-1:2005范围内的机械和相关设备。 本欧洲标准不适用于CEN在本欧洲标准出版前制造的清洁机

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.
