IEC 61228:2020 is available as IEC 61228:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 61228:2020 describes the method of measuring, evaluating and specifying the UV irradiation characteristics of fluorescent ultraviolet lamps that are used in appliances for tanning purposes. It includes specific requirements regarding the marking of such lamps. This third edition cancels and replaces the second edition published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- maintenance code: description of the depreciation of the UV irradiance lamp during operation;
- operating position: information added for single capped lamps;
- spectroradiometric measuring system: new information about distance between sensor and lamp axis;
- measurement and evaluation procedure: separated detailed information for double capped fluorescent UV lamps and single capped fluorescent UV lamps;
- Annex C (normative), Method of test for irradiance maintenance: new information added;
- Annex D (normative), Reflector gauge: new information added;
- Annex E (normative), Lamp datasheets for measurement: complementary information added.

IEC TR 63130:2018(E) describes the current state of experts’ opinions on the standardization of metal halide lamps to cover the relevant parameters for hot restrike and for dimming in combination with low frequency square wave ballasts. It provides guidelines for supplementing or modifying IEC 61167 in order that these conditions are covered.

Describes how the concentrations of dissolved gases or free gases may be interpreted to diagnose the condition of oil-filled electrical equipment in service and suggests future action. Applicable to electrical equipment filled with mineral insulating oil and insulated with cellulosic paper or pressboard-based solid insulation. Information about specific types of equipment such as transformers (power, instrument, industrial, railways, distribution), reactors, bushings, switchgear and oil-filled cables is given only as an indication in the application notes. May be applied only with caution to other liquid-solid insulating systems. In any case, the indications obtained should be viewed only as guidance and any resulting action should be undertaken only with proper engineering judgement.

IEC 62612:2013 specifies the performance requirements, together with the test methods and conditions, required to show compliance of LED lamps with integral means for stable operation, intended for domestic and similar general lighting purposes, having:
- a rated power up to 60 W;
- a rated voltage of > 50 V a.c. up to 250 V a.c.;
- a lamp cap as listed in IEC 62560. This first edition of IEC 62612 cancels and replaces IEC/PAS 62612. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC/PAS 62612.
a) The standard explicitly states that real life time tests are not part of the test regime. Instead, a period of up to 6 000 h is chosen in order to assess manufacturers' claims of maintenance.
b) Technical features have been adapted to IEC/PAS 62717 (performance of LED modules) as far as possible. Examples are the family approach and the temperature measuring point.
c) Marking requirements are shifted from the product to the packaging.
d) The number of lamps to be tested is made test specific, not general.
e) First requirements are given for setting the colour for colour adjustable lamps and the luminous flux level of dimmable lamps.
f) The structure of tests is clearly divided between requirement and compliance.
g) Statistical compliance is separated into individual and average.
h) Light output requirements are extended to luminous intensity distribution, peak intensity, beam angle and efficacy.
i) The use of the terms "correlated colour temperature" and "chromaticity coordinates" is corrected.
j) The number of tolerance categories is reduced from 8 to 4, and split between initial and maintained values.
k) Colour rendering is differently assessed at initial and maintained state.
l) Three lumen maintenance categories are given instead of five.
m) The endurance tests are completely re-established.
n) The verification (formerly: assessment) clause is completed.
o) Information for luminaire design is added.
p) Stabilisation is more precise (Annex A on the method of measuring lamp characteristics) and extension is made for the additional photometric and colorimetric parameters.
q) Annex B on measuring luminous flux is contained in Annex A. New Annex B provides the photometric code.
r) Further annexes are added: Annex C and D for displacement factor, Annex E for life time metrics/reliability and Annex F for examples of LED dies and LED packages. The contents of the corrigendum of October 2016 have been included in this copy.

IEC/TR 62750:2012(E) applies to fluorescent lamp dimming systems. It deals with the interface of fluorescent lamps and dimming electronic controlgear. A unified framework for standardization of fluorescent lamp dimming systems and the associated parameter calculation method are described in this Technical Report.
