This part of IEC 60216 specifies the experimental and calculation procedures for deriving the thermal endurance characteristics, temperature index (TI) and relative temperature index (RTI) of an electrical insulating material (EIM) using the "fixed time frame method (FTFM)".
In this protocol, the ageing takes place for a small number of fixed times, using the appropriate number of ageing temperatures throughout each time, the properties of the specimens being measured at the end of the relevant time interval. This differs from the procedure of IEC 60216-1, where ageing is conducted at a small number of fixed temperatures, property measurement taking place after ageing times dependent on the progress of ageing.
The diagnostic tests employed in the fixed time frame method are restricted to destructive tests. The method has not yet been applied to non-destructive or proof test procedures.
Both the TI and the RTI determined according to the FTFM protocol are derived from experimental data obtained in accordance with the instructions of IEC 60216-1 and IEC 60216-2 as modified in this part of IEC 60216. The calculation procedures and statistical tests are modified from those of IEC 60216-3 and IEC 60216-5.

This part of IEC 61340 describes test methods for measuring the rate of dissipation of static charge of insulating and static materials and products.
It includes a generic description of test methods and detailed test procedures for specific applications.
The two test methods for measuring charge decay time, one using corona charging and one using a charged metal plate are different and might not give equivalent results. Nevertheless, each method has a range of applications for which it is best suited. The corona charging method is suitable for evaluating the ability of materials, for example textiles, packaging, etc., to dissipate charge from their own surfaces. The charged metal plate method is suitable for evaluating the ability of materials and objects such as gloves, finger cots, hand tools, etc. to dissipate charge from conductive objects placed on or in contact with them. The charged plate method might not be suitable for evaluating the ability of materials to dissipate charge from their own surfaces.
In addition to its general application, this horizontal standard is also intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 108.
One of the responsibilities of a technical committee is, wherever applicable, to make use of horizontal standards in the preparation of its publications. The contents of this horizontal standard shall not apply unless specifically referred to or included in the relevant publications.

This standard describes two test methods for the evaluation of electrical insulating materials for use under severe ambient conditions at power frequencies (45 Hz to 65 Hz) by the evaluation of the resistance to tracking and erosion, using a liquid contaminant and inclined plane specimens. The two methods are:
- Method 1: test at constant voltage,
- Method 2: test at stepwise increased voltage.
Method 1 is the most widely used method as there is less need for continual inspection.
The test conditions are designed to accelerate the production of the effects, but do not reproduce all the conditions encountered in service.

Test methods are based on those specified in IEC 61340-5-1 and other parts of the IEC 61340 series, and are simplified where necessary for the purposes of compliance verification, to be performed by competent personnel.
Users can, by reference to this document in their compliance verification plan, adopt the necessary test methods described herein without change or addition. Alternatively, test methods described in this document can be adapted to match the requirements of their own ESD control program, provided deviations in equipment or procedure are documented in their compliance verification plan.
Compliance verification test frequency is not specified in this document. Guidance on how users can consider compliance verification test frequency is given in informative Annex A.
Product qualification is excluded from the scope of this document.

IEC/TR 61340-1:2012 describes the fundamental principles of electrostatic phenomena including charge generation, retention and dissipation and electrostatic discharges. Methods for measuring electrostatic phenomena and related properties of materials are described in a general way. Hazards and problems associated with electrostatic phenomena and principles of their control are outlined. Useful applications of electrostatic effects are summarized. The purpose of this technical report is to serve as a reference for the development of electrostatics related standards, and to provide guidance for their end-users. The contents of the corrigendum of March 2013 and the corrigendum 2 of December 2017 have been included in this copy.

IEC TS 62749:2020 is available as IEC TS 62749:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC TS 62749:2020 specifies the expected characteristics of electricity at the SUPPLY TERMINALS of public low, medium and high voltage, 50 Hz or 60 Hz, networks.
NOTE 1 The boundaries between the various voltage levels can be different for different countries/regions. In the context of this TS, the following terms for system voltage are used:
- low voltage (LV) refers to less than or equal to 1 kV;
- medium voltage (MV) refers to between 1 kV and 35 kV;
- high voltage (HV) refers to between 35 kV and 230 kV.
While power quality is related to EMC in a number of ways this document is not an EMC publication. This second edition cancels and replaces the first edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) minimum number of remaining data for weekly analysis,
b) improvement of the compatibility between EN 50160 and IEC TS 62749,
c) further explanation of the conception of daily sliding window,
d) further explanation of the aggregation method used for events,
e) further explanation of the relation between Power Quality and EMC,
f) addition of a new definition of mains communicating system (MCS),
g) addition of a new Annex G: Other phenomena,
h) transfer of the main content of IEC TR 62510 to IEC TS 62749.
