This document specifies requirements for design@ construction@ testing and marking of hand-held@ portable and transportable vacuum cleaners and dust collectors@ including their accessories@ constructed to Group II categories 2G and 3G and to Group II categories 2D and 3D@ intended for the collection of combustible or non-combustible dusts and flammable or non-flammable liquids in potentially explosive atmospheres. A potentially explosive atmosphere may be generated by the equipment during its intended use. It covers equipment driven by electricity and by pneumatic power. This document deals with all significant hazards@ hazardous situations and events relevant to vacuum cleaners and dust collectors@ 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. For other specific applications a specific assessment shall be performed. This document does not cover equipment used to collect toxic dusts where there is a health risk if dust passes through the filter element. This document does not cover either the collection of dusts which have explosive and unstable properties (UN transport class 1@ class 4.1 and class 5.2). This document covers vacuum cleaners with an internal dust loaded volume of maximum 200 l. This document does not apply to pumps@ where the inlet nozzle is submerged into a liquid@ and all conveying applications. This document does not apply to Group I vacuum cleaners and dust collectors for mining. For an easier readability@ all types of equipment concerned by this standard are referred as ??Vacuum cleaner?? in this document. NOTE Collecting dust is recognized as a suitable action in view to participate to prevention against explosion.
