ÖNORM EN 17348

This document specifies requirements for design, construction, testing and marking of hand-held, portable and transportable vacuum cleaners, including their accessories, constructed to Group II, categories 2G or 3G (of explosion groups IIA, IIB, IIB plus hydrogen), and to Group II, categories 2D or 3D (of explosion groups IIIA, IIIB and IIIC), intended for the collection of combustible or non-combustible dusts and flammable or non-flammable liquids in potentially explosive atmospheres. A potentially explosive atmosphere could be generated by the equipment during its intended use. This document applies to equipment driven by electric power and by pneumatic power. This document gives guidelines for dealing with significant hazards, hazardous situations and/or events relevant to vacuum cleaners when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. Typical applications for the concerned equipment are: - collection of dust produced by machinery at the point of generation; - general housekeeping around machinery and of working areas; and/or - collection of spills; - cleaning of equipment during maintenance operations; and/or - collection of specific waste. For the collection of dust in the presence of flammable liquids or vapours, a specific risk assessment is performed if this is part of the vacuum cleaners intended conditions of use and additional precautions beyond what is described in this document can be required. For the collection of low-conductivity flammable liquids, a specific risk assessment is performed if this is part of the vacuum cleaners intended conditions of use and additional precautions beyond what is described in this document can be required. This document applies to vacuum cleaners with an internal dirty air volume of maximum 250 l. The present version of the document does not apply to battery operated equipment. This document does not apply to vacuum trucks. This document applies to vacuum cleaners of canister and back-pack types. This document does not apply to upright vacuum cleaners. This document does not apply to motorized cleaning head accessories. This document does not apply to applications where the substances are conveyed into a separate receiving container. This document does not apply to equipment intended for use in underground parts of mines as well as those parts of surface installations of such mines endangered by firedamp and/or combustible dust. For an easier readability, all types of equipment concerned by this document are referred as a “vacuum cleaner”.
