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 TS 63336:2024, which is a technical specification, applies to the commissioning of voltage-sourced converter (VSC) high voltage direct current (HVDC) systems which consist of two converter stations and the connecting HVDC transmission line.
The tests are generally applied to all HVDC configurations and could require addition or deletion to match the given solution.
This document provides guidance on the planning of commissioning activities. The commissioning described in this document is implemented through on-site testing on the whole system functionality, including testing on the subsystem and system. This document provides the scope, procedures and acceptance criteria of the tests.
Factory system tests, on-site equipment tests, electrode tests, and trial operation are not included in this document.

Establishes a classification of surface insulations for electrical steel sheet, strip and laminations according to their general composition, relative insulating ability and function. These surface insulations are either oxide layers or applied coatings. The purpose of this classification is to create a nomenclature for the various types of surface insulations and to assist users of surface insulations by providing general information about the chemical nature and use of the surface insulations. It is not the intent of this classification to specify insulation requirements in terms of specific values of surface insulation resistance. Such requirements are agreed between the purchaser and the steel producer, where applicable. The classification is used in conjunction with the various specifications for cold rolled electrical steels (see the standards in the IEC 60404-8 series in Clause 2).

This document specifies methods to determine the mechanical integrity of filters under defined conditions that can be encountered in abnormal operating environments. It describes the test methods for filter elements, independent of any ageing procedures like pulsing, loading, temperature cycles, wet conditions or others. The test procedure is intended for filters operating in the range of 0,24 m3/s (850 m3/h) up to 2,36 m3/s (8 500 m3/h). Filter elements with a lower efficiency than ISO T5 (ePM10) according to ISO 29461-1 are excluded. To ensure the comparability of the test results, only new filter elements or those loaded up to 625 Pa or maximum 800 Pa according to ISO 29461-1 are tested. This document does not describe a standardized method to measure the fractional or gravimetric efficiency. The efficiency of the filter element can be tested according to ISO 29461-1. The performance results obtained according to this document cannot be quantitatively applied (by themselves) to predict performance in real use.

b) in Clause 3 specific definitions are added for "in service", "normal operating condition" and "normal use";
c) internal arc testing on pole-mounted switchgear is taken out of this document, as it is now covered by the specific standard IEC 62271‑214:2019;

Polymeric insulators covered by this technical report include both solid core and hollow insulators. They are intended for use on overhead lines and in indoor and outdoor equipment with a rated voltage greater than 1 000 V. The object of this technical report is:
- to define the common terms used;
- to give the background behind the development and use of the 5 000 h multiple stress test and the tracking wheel test;
- to describe the test methods for the 5 000 h multiple stress test and the tracking wheel tests on polymeric insulators;
- to describe possible acceptance or failure criteria, if applicable. Key words: polymeric insulators, multiple stress test, 5000 h

IEC 60317-8:2010 specifies the requirements of enamelled round copper winding wires of class 180 with a sole coating based on polyesterimide resin, which may be modified provided it retains the chemical identity of the original resin and meets all specified wire requirements. The main changes with respect to the previous edition are:
- introduction of requirements for appearance;
- new reference to resistance to refrigerants test method;
- deletion of high temperature failure requirements;
- introductin of pin hole test requirements.

IEC 60317-28:2013 specifies the requirements of enamelled rectangular copper winding wire of class 180 with a sole coating based on polyesterimide resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. NOTE - A modified resin is a resin that has undergone a chemical change, or contains one or more additives to enhance certain performance or application characteristics. The range of nominal conductor dimensions covered by this standard is:
- width: min. 2,0 mm max. 16,0 mm;
- thickness: min. 0,80 mm max. 5,60 mm. Wires of grade 1 and grade 2 are included in this specification and apply to the complete range of conductors. The specified combinations of width and thickness as well as the specified width/thickness ratio are given in IEC 60317-0-2:2013. This second edition cancels and replaces the first edition published in 1990, Amendment 1:1997 and Amendment 2:2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- new subclause containing general notes on winding wire, formerly a part of the scope;
- revision to references to IEC 60317-0-2:2013 to clarify that their application is normative;
- new 3.3, Appearance;
- deletion of Clause 22, High temperature failure;
- modification to Clause 23, Pin hole test. Keywords: requirements of enamelled rectangular copper winding wire, class 180, sole coating based on polyesterimide resin
This publication is to be read in conjunction with IEC 60317-0-2:2013.
