Draft Details

This International Standard covers electrical mobile motor-operated vacuum cleaners Equipment Protection Level (EPL) Dc.

1DV DR Modification of Clause 1 to replace it with the following:

1DV.1 This International Standard covers electrical mobile motor-operated vacuum cleaners Equipment Protection Level (EPL) Dc for use in Zone 22 locations.

This includes dust extractors, for wet suction or dry suction, intended for commercial indoor use with or without attachments, to collect combustible dust in an explosive dust   atmosphere.

1DV.2 This includes dust extractors, for wet suction or dry suction, intended for commercial indoor use with or without attachments, to collect combustible dust in an explosive dust   atmosphere.  Vacuum cleaners intended for Zone 22, Group IIIC are not permitted in the US because there are only Zone 20 and Zone 21 locations for this dust group.

This document supplements and modifies the requirements of IEC 60079-0. Whenever a requirement of this standard is in conflict with a requirement of IEC 60079-0, the requirement   of this standard will take precedence.

1DV.3 This document supplements and modifies the requirements of IEC 60079-0 UL 60079-0 and CSA C22.2 No. 60079-0. Whenever a requirement of this standard is in conflict with a requirement of IEC 60079-0 UL 60079-0 or CSA C22.2 No. 60079-0, the requirement   of this standard will take precedence.

The following power systems are covered:

– mains powered motors up to a rated voltage of 250 V for single-phase appliances and 480 V for other appliances.

This document does not cover specific hazards associated with extreme ambient temperatures (less than –20 °C or higher than 40 °C) unless otherwise marked by the manufacturer as given in IEC 60079-0. The temperatures shall not exceed the temperature range of –20 °C to +60 °C.

1DV.4 This document does not cover specific hazards associated with extreme ambient temperatures (less than –20 °C or higher than 40 °C) unless otherwise marked by the manufacturer as given in IEC 60079-0 UL 60079-0 or CSA C22.2 No. 60079-0. The temperatures shall not exceed the temperature range of –20 °C to +60 °C.

1DV.5 This document does not cover specific hazards associated with the suction of flammable liquids.

This document does not cover motorized cleaning heads for which additional requirements are under consideration.

This document does not apply to

– back-pack vacuum cleaners;
– vacuum cleaners with a traction drive;
– vacuum cleaners and water-suction cleaning appliances for household use (IEC 60335-2-2 CSA-E60335-2-2, CSA C22.2 No. 243 / UL 1017);
– floor treatment machines for commercial use (IEC 60335-2-67, IEC  60335-2-72) with or without a traction drive
– spray extraction machines for commercial use (IEC 60335-2-68 CSA C22.2 No. 60335-2-68 / UL 60335-2-68);
– hand-held mains-operated electrical garden blowers, vacuums and blower vacuums (IEC 60335-2-100 CSA C22.2 No. 243 / UL 1017);
– hand-held and transportable motor-operated electric tools (IEC 62841 series CSA C22.2 No. 60745 (all parts), UL 60745 (all parts), CAN/CSA E1029 (all parts), UL987, CSA C22.2 No. 71.2, CSA C22.2 No. 62841 (all parts), UL 62841 (all parts);
– appliances for medical purposes (IEC 60601-1 CAN/CSA C22.2 No. 60601-1 / UL 60601-1, AAMI ES 60601-1);
– machines designed for use in corrosive environments;
– machines designed for picking up flammable liquids or combustible liquids with a flash point below 55 °C;
– machines designed for use in explosive environments due to the presence of explosive substances or pyrotechnical products, or unstable chemical substances.

1DV.6 Where references are made to IEC and ISO standards, the reference requirements found in these standards apply as modified by any applicable US or Canadian National Differences for the standard (see Clause 2).
