Title Ballasts for discharge lamps (excluding tubular fluorescent lamps) - General and safety requirements
Project Number 3671
Abstract/Scope This standard specifies safety requirements for ballasts, for discharge lamps such as high-pressure mercury vapour, low-pressure sodium vapour, high-pressure sodium vapour and metal halide lamps. Section One specifies general requirements and Section Two specifies thermal and mechanical requirements. The standard covers inductive-type ballasts for use on a.c. supplies up to 1 000 V at 50 Hz or 60 Hz associated with discharge lamps, having rated wattages, dimensions and characteristics as specified in the relevant standards according to EN 60188, EN 60192 and EN 60662. Tests in this standard are type tests. Requirements for testing individual ballasts during production are not included. Notes 1 For certain types of discharge lamp an ignitor is required. Ballasts for tubular fluorescent discharge lamps are covered by EN 60920.

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of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
