IEC 62811-2015 pdf download.AC and/or DC-supplied electronic controlgear for discharge lamps (excluding fluorescent lamps) – Performance requirements for low frequency square wave operation.
This International Standard specifies performance requirements for electronic controlgear for use on a.c. and/or d.c. supplies up to 1 000 V and/or a.c. supplies up to 1 000 V at 50 Hz or 60 Hz, associated with discharge lamps, as specified in IEC 61 1 67, which have information for low frequency square wave operation, where the frequency range of the low frequency is from 70 Hz to 400 Hz. Tests in this standard are type tests. Requirements for testing individual controlgear during production are not included. There are regional standards regarding the regulation of mains current harmonics and immunity for end products like luminaires and independent controlgear. In a luminaire, the controlgear is dominant in this respect. Controlgear, together with other components, should comply with these standards. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

3 Terms and definitions For the purposes of this document, the terms and definitions given in IEC 60050-845 as well as the following apply.
3.1 reference ballast
special resistive ballast for lamps, for operation on low frequency square wave designed for the purpose of providing comparison standards for use in testing ballasts, for the selection of reference lamps and for testing regular production lamps under standardized conditions
Note 1 to entry: It is essentially characterized by the fact that, at its rated frequency, it has a stable voltage/current ratio which is relatively uninfluenced by variations in current, temperature and magnetic surroundings, as outlined in this standard.

3.2 reference lamp
discharge lamp selected for the purpose of testing ballasts and which, when associated with a reference ballast under specified conditions, has electrical values which are close to the objective values given in a relevant specification
[SOURCE: IEC 60050:1 987, 845-07-55]
3.3 calibration current of a reference ballast
value of the current on which are based the calibration and control of the reference ballast
Note 1 to entry: Such a current should preferably be approximately equal to the rated or typical current of the lamps for which the reference ballast is suitable.
[SOURCE: IEC 61 347-1 :2007, 3.4, modified — In the note to entry the words “rated running”
are replaced by “rated or typical”]
3.4 total circuit power
total power dissipated by controlgear and lamp in combination, at rated voltage and frequency of the controlgear

3.5 displacement factor
cosφ 1 cosine of the phase difference between the fundamental of the mains voltage and the fundamental of the mains current.IEC 62811 pdf download.
