IEC 60587:2022 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.
This edition includes the following significant technical changes with respect to the previous edition:
a) an improved description of the experimental methods has been implemented;
b) an improved description of the preparation of the test specimens has been implemented;
c) a more detailed description of the electrode material and of the electrode quality has been added;
d) evaluation criterion B (track length) has been removed for testing according to test method 2 (stepwise tracking voltage) as it is not applicable.

IEC 62899-201-2:2021(E) defines measurement methods for the properties of stretchable substrates, in order to use evaluating stretchable functional layers (conductive, semiconducting, and insulating) formed by printing technologies. If the same types of materials as the substrates are used for the cover lay film, they are also subjected to the measurement defined in this document.
Stretchable substrates handled by this document apply to substrates subjected to repeated bending with wiring elements demanding a high level of performance, such as fabric integrated wearable devices or skin patchable devices.
This document does not define the required characteristics of the stretchable substrate. It provides test methods to characterize (pre-qualify) the substrates that are intended to be used for printing conductors and insulators for the purposes of manufacturing stretchable layers or structures.

IEC TR 62039:2021(E) presents the important material properties of polymeric materials used in outdoor insulation and, where applicable, lists standardized test methods including minimum requirements. If no standardized tests are available, the test methods reported in literature are summarized.
This document is valid for insulating materials having polymeric insulation, which are used in outdoor high voltage electrical applications with a system voltage greater than 1 000 V AC and 1 500 V DC (several tests are only defined for alternating current, which are not applicable for direct current). Such applications are relevant where the housing is an integral part of the device, for example in surge arresters and cable terminations. The scope of this document is limited to the insulation materials only and is not generally intended for coating materials (coating materials are, for example, thin layers applied on toughened glass and ceramic). Some tests mentioned in this document are applicable for coating and are under consideration by CIGRE. The performance of insulators in service depends on several factors such as the type of material, the design and environmental conditions. Consequently, the choice of materials that fulfil the requirements listed in Table 1 is a necessary condition but does not guarantee satisfactory performance when used in outdoor insulation.

endurance characteristics from experimental data obtained in accordance with the instructions
of IEC 60216-1 and IEC 60216-2 [1]1, using fixed ageing temperatures and variable ageing
times.
The experimental data can be obtained using non-destructive, destructive or proof tests. Data
obtained from non-destructive or proof tests can be incomplete, in that it is possible that
measurement of times taken to reach the end-point will have been terminated at some point
after the median time but before all specimens have reached end-point.
The procedures are illustrated by worked examples, and suitable computer programs are
recommended to facilitate the calculations.

IEC 62899-202-7:2021(E) provides a test method to measure the peel strength of a printed layer on a flexible substrate. This method calls for peeling the flexible substrate instead of an additional metal electroplating on the printed layer. The method described in this document can be used to compare the peel strengths of the printed layers on the same flexible substrate and thickness conditions. It can be used when the adhesion between the printed layer and flexible substrate is weaker than any other interface between the printed layer and the adhesive, the adhesive and the panel.

This document specifies the method of test for the determination of the proof and comparative
tracking indices of solid insulating materials on pieces taken from parts of equipment and on
plaques of material using alternating voltage.
This document provides a procedure for the determination of erosion when required.
NOTE 1 The proof tracking index is used as an acceptance criterion as well as a means for the quality control of
materials and fabricated parts. The comparative tracking index is mainly used for the basic characterization and
comparison of the properties of materials.
This test method evaluates the composition of the material as well as the surface of the
material being evaluated. Both the composition and surface condition directly influence the
results of the evaluation and are considered when using the results in material selection
process.
Test results are not directly suitable for the evaluation of safe creepage distances when
designing electrical apparatus.
NOTE 2 This is in compliance with IEC 60664-1, Insulation coordination for equipment within low-voltage
systems – Part 1: Principles, requirements and tests.
NOTE 3 This test discriminates between materials with relatively poor resistance to tracking, and those with
moderate or good resistance, for use in equipment which can be used under moist conditions. More severe tests of
longer duration are available for the assessment of performance of materials for outdoor use, utilizing higher
voltages and larger test specimens (see the inclined plane test of IEC 60587). Other test methods such as the
inclined method can rank materials in a different order from the drop test given in this document.
This basic safety publication focusing on a safety test method is primarily intended for use by
technical committees in the preparation of safety publications in accordance with the
principles laid down in IEC Guide 104 and lSO/lEC Guide 51.
One of the responsibilities of a technical committee is, wherever applicable, to make use of
basic safety publications in the preparation of its publications.

IEC 61333:2019 specifies marking locations and a coding system of marking on ferrite cores. An alphanumerical marking printed or attached to cores reduces the risk of incorrect assembly, mixing of materials and/or mixing of gapped cores on an assembly line. The markings of the inductance factor AL value or of the gap length are especially important to avoid this kind of problem, and their coding system is specified in this document. This edition includes the following significant technical changes with respect to the previous edition: a) the title of the document was changed; b) the scope of this document was expanded; c) the marking position instructions for ring cores, planar cores, RM-cores, PQ-cores and pot-cores were added in Clause 4 with a few additional descriptions; d) the four-digit-maximum limit of material identification code has been deleted in 5.2; e) in Table 1, the unit of AL has been changed from "nH" to "nH/N2".

IEC TR 61244-4:2019(E) provides general guidance for the evaluation/verification of electrical insulation materials (EIM) and electrical insulation systems (EIS) intended to be used in types of equipment exposed to ionizing radiation. Beside sensors, actuators/motors as well as plugs and terminals, cables are a well-known typical application of those EIM and EIS. Their type spectrum covers low voltage power cables, control cables and instrumentation cables. Because of their comparable simple design, cables are the ideal type of equipment to study EIM and EIS degradation processes. But the results of these studies can be easily transferred to the enumerated types of equipment.
Nonetheless, this document provides a state-of-the art report on qualification/verification procedures used to simulate simultaneous effects of temperature and radiation at varying intensities rather than give detailed test programmes valid for specific test methods.
NOTE 1 Use of this document with specific products can require specification of additional product related procedures.
NOTE 2 Some of the procedures described in this document are emerging technologies. Therefore, specified prerequisites, former experiences as well as boundary conditions can be additionally taken into account.
