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
