1.1 This European Standard specifies safety requirements for design, construction, operation, adjustment, setting, cleaning and maintenance of a machine. 1.2 This standard covers the following machines (see annex C and Figures 1 and 2 for typical configurations): a) horizontal rotating vessels; b) inclined rotating vessels. 1.3 This standard does not apply to machines using substances containing solvent, that would generate fume and/or vapour detrimental to health, or that may lead to fire or explosive atmosphere. 1.4 This standard takes account of intended use, foreseeable misuse, component and systems failure. The machines are for fixed installation. 1.5 This document is not applicable to the rotating vessels which are manufactured before the date of its publication as EN. 1.6 This standard does not establish any requirements for electromagnetic disturbances. NOTE Directive 94/9/EC concerning equipment and protective systems intended for use in potentially explosive atmospheres can be applicable to the type of machine or equipment covered by this European Standard. The present standard does not necessarily comply with Directive 94/9/EC. Additional safety requirements in a future revision of this standard can be necessary to satisfy Directive 94/9/EC.
