IEC 60929:2011+A1:2015 specifies performance requirements for electronic control gear for use on a.c. at 50 Hz or 60 Hz and/or d.c. supplies, both up to 1 000 V, with operating frequencies deviating from the supply frequency, associated with fluorescent lamps as specified in IEC 60081 and IEC 60901, and other fluorescent lamps for high-frequency operation. This fourth edition cancels and replaces the third edition published in 2006, IEC 60925 published in 1989, its Amendment 1 (1996) and its Amendment 2 (2001). This fourth edition constitutes a technical revision. The essential change with respect to the third edition is the extension to DC supplied control gear and the deletion of the requirements for digital signal control of electronic control gear. The contents of the corrigendum of September 2011 have been included in this copy. This consolidated version consists of the fourth edition (2011) and its amendment 1 (2015). Therefore, no need to order amendment in addition to this publication.

This standard specifies performance requirements for ballasts, excluding resistance types, for use on a.c. supplies up to 1 000 V at 50 Hz or 60 Hz, associated with tubular fluorescent lamps with pre-heated cathodes operated with or without a starter or starting device and having rated wattages, dimensions and characteristics as specified in IEC 60081 and 60901. It applies to complete ballasts and their component parts such as resistors, transformers and capacitors. This consolidated version consists of the second edition (2004) and its amendment 1 (2006). Therefore, no need to order amendment in addition to this publication.

IEC 60904-9:2020 is applicable for solar simulators used in PV test and calibration laboratories and in manufacturing lines of solar cells and PV modules. This document define classifications of solar simulators for use in indoor measurements of terrestrial photovoltaic devices. Solar simulators are classified as A+, A, B or C based on criteria of spectral distribution match, irradiance non-uniformity in the test plane and temporal instability of irradiance. This document provides the required methodologies for determining the classification of solar simulators in each of the categories. A solar simulator which does not meet the minimum requirements of class C cannot be classified according to this document. This document is used in combination with IEC TR 60904-14, which deals with best practice recommendations for production line measurements of single-junction PV module maximum power output and reporting at standard test conditions.
This third edition cancels and replaces the second edition issued in 2007. This edition includes the following significant technical changes with respect to the previous edition:
- Changed title;
- Added spectral match classification in an extended wavelength range;
- Introduction of new A+ class;
- Definition of additional parameters for spectral irradiance evaluation;
- Added apparatus sections for spectral irradiance measurement and spatial uniformity measurement;
- Revised procedure for spectral match classification (minimum 4 measurement locations);
- Revised measurement procedure for spatial uniformity of irradiance;
- Added informative Annex for sensitivity analysis of spectral mismatch error related to solar simulator spectral irradiance. -

IEC 60904-8:2014 specifies the requirements for the measurement of the spectral responsivity of both linear and non-linear photovoltaic devices. The spectral responsivity of a photovoltaic device is used in cell development and cell analysis, as it provides a measure of recombination and other processes occurring inside the semiconductor or cell material system. The main technical changes with respect to the previous edition are listed below: - re-writing of the clause on testing; - addition of a new clause for the measurement of series-connected modules; - addition of the requirements of ISO/IEC 17025.

IEC 60904-8-1:2017 gives guidance for the measurement of the spectral responsivity of multi-junction photovoltaic devices. It is principally intended for non-concentrating devices, but parts may be applicable also to concentrating multi-junction PV devices. The SR is required for analysis of measured current-voltage characteristics of multi-junction PV devices as described in IEC 60904-1-1.
