Organization: UL
Publication Date: 7 April 2020
Status: active
Page Count: 45
scope:

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

This document specifies requirements for the construction, testing and marking for Group II electrical equipment with type of protection "n" which includes; sealed devices "nC", hermetically sealed devices "nC", non-incendive components "nC" and restricted breathing enclosures "nR" intended for use in explosive gas atmospheres. This document applies to electrical equipment where the rated input voltage does not exceed 15 kV r. m. s. AC or DC including where the internal working voltages of the Ex product exceeds 15 kV, for example starters for HID luminaires.

Where references are made to IEC, IEC/IEEE, ISO, ISO/IEC standards, the referenced requirements found in these standards shall apply as modified by any applicable US National Differences for the standard (see Clause 2).

This document supplements and modifies the general requirements of UL 60079-0, except as indicated in Table 1. Where a requirement of this document conflicts with a requirement of UL 60079-0, the requirement of this document takes precedence.
