Reference HD 22.7 S2:1995/A2:2004
Title Cables of rated voltages up to and including 450/750 V and having cross-linked insulation - Part 7: Cables with increased heat resistance for internal wiring for a conductor temperature of 110 °C
Project Number 15319
Abstract/Scope This Part 7 of the HD details the particular specifications for rubber insulated cables of rated voltages Uo/U up to and including 450/750 V for internal wiring of electrical apparatus where wiring is operated in a high temperature zone. The high temperature may be caused by high ambient temperature and/or by heat generated by the equipment. The cables shall comply with the appropriate requirements given in Part 1 and the particular requirements of this part. NOTE: The overall dimensions of the cables of this Part of HD 22 have been calculated in accordance with EN 60719.

Normative reference (6)  

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
