IEC 60127-8:2018 relates to fuse resistors with particular overcurrent protection rated up to AC 500 V and/or DC 500 V for printed circuits and other substrate systems, used for the protection of electric appliances, electronic equipment and component parts thereof, normally intended to be used indoors.
It does not apply to fuse resistors with particular overcurrent protection for appliances intended to be used under special conditions, such as in a corrosive or explosive atmosphere.
The object of this part of IEC 60127 is
a) to establish uniform requirements for fuse resistors with particular overcurrent protection so as to protect appliances or parts of appliances in the most suitable way;
b) to define the performance of the fuse resistors with particular overcurrent protection, so as to give guidance to manufacturers of electrical appliances and electronic equipment and to ensure replacement of fuse resistors with particular overcurrent protection by those of similar dimensions and characteristics;
c) to establish uniform test methods for fuse resistors with particular overcurrent protection, so as to allow verification of the values (for example rated dissipation, functioning characteristic and rated breaking capacity values) specified by the manufacturer.
This part of IEC 60127 applies in addition to the requirements of IEC 60127-1.
This first edition of IEC 60127-8 cancels and replaces IEC PAS 60127-8:2014.
This international standard is to be used in conjunction with IEC 60127-1.

IEC 61643-332:2024 describes the theory of operation, principles for the selection and application of MOVs to be connected to power lines or telecommunication or signalling circuits, up to 1 000 V AC or 1 500 V DC. These SPCs are designed to protect apparatus or personnel, or both, from high transient voltages. This document applies to MOVs having two electrodes and voltage dependents elements with or without disconnectors. It does not apply to assemblies that include MOVs and their influence on the MOV's characteristics. This standard specifically discusses the zinc-oxide type of MOVs.

- check and redefine some definitions, harmonize with IEC 60050:
o Check and harmonize terms and definitions specific to railway terminology with IEC 60050 chapters 811 and 821. If modification of a definition is essential, consider harmonization with a recent definition used in a railway specific standard and which should postdate the IEC entry.

- adaptation of the Scope of this standard (include electrical safety related interface with vehicles, extension for electrified road transport – as shown above)
- Incorporate such small technical improvements from IEC 62128, made when transferring from previous version 50122-1, only insofar as these are essential for the coherence of the standard 50122-1
- Harmonize definitions with other railway standards (esp. EN 50119)
- check and redefine some definitions, harmonize with IEC 60050:
o Check and harmonize terms and definitions specific to railway terminology with IEC 60050 chapters 811 and 821. If modification of a definition is essential, consider harmonization with a recent definition used in a railway specific standard and which should postdate the IEC entry.
o Check and harmonize terms and definitions specific to electric shock with IEC60050 chapter 195 except where the terms and definitions in IEC 61140:2016 are appropriate and postdate IEC 60050 entry.
o Check and harmonise other terms and definitions with IEC 50050 where appropriate.

IEC 60269-2:2013 provides supplementary requirements for fuses for use by authorized persons and are generally designed to be used in installations where the fuse-links are accessible to, and may be replaced by, authorized persons only. Fuses for use by authorized persons according to the following fuse systems also comply with the requirements of the corresponding subclauses of IEC 60269-1, unless otherwise defined in this standard. This standard is divided into fuse systems, each dealing with a specific example of standardized fuses for use by authorized persons: - Fuse system A: Fuses with fuse-links with blade contacts (NH fuse system), - Fuse system B: Fuses with striker fuse-links with blade contacts (NH fuse system), - Fuse system C: Fuse-rails (NH fuse system), - Fuse system D: Fuse-bases for busbar mounting (NH fuse system), - Fuse system E: Fuses with fuse-links for bolted connections (BS bolted fuse system), - Fuse system F: Fuses with fuse-links having cylindrical contact caps (NF cylindrical fuse system), - Fuse system G: Fuses with fuse-links with offset blade contacts (BS clip-in fuse system), - Fuse system H: Fuses with fuse-links having 'gD' and 'gN' characteristic (class J and class time delay and non time delay fuse types), - Fuse system I: gU fuse-links with wedge tightening contacts, - Fuse system J: Fuses with fuse-links having 'gD class CC' and 'gN class CC' characteristics (class CC time delay and non-time delay fuse types), - Fuse system K: gK fuse-links with blade for bolted connections - High fuse-link ratings from 1 250 A up to 4 800 A (master fuse-links). This fifth edition of IEC 60269-2 cancels and replaces the fourth edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: 1. fuse systems A and B: modified values for the power dissipation of NH aM fuse-links; 2. fuse systems A and B: introduction of dimension r for NH fuse-links; 3. addition of new fuse system K: gK fuse-links with contacts for bolted connections. Key Words: fuse systems A to K, requirements for fuses
