IEC 60112:2025(Main)

Method for the determination of the proof and the comparative tracking indices of solid insulating materials

CORRECTED VERSION 2026-02
IEC 60112:2025 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. 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. The described test method is designed for a test voltage up to 600 V AC, because higher test voltages and DC voltage will lead to a reduced test severity. Test results are not directly suitable for the evaluation of safe creepage distances when designing electrical apparatus. The results of this method have been used for insulation coordination of equipment. It is important that use of these results also considers the overvoltage levels, creepage distances, and establishes the pollution degree to which the product insulation system will be expected to be subjected. This is in compliance with IEC 60664-1. 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. This sixth edition cancels and replaces the fifth edition published in 2020. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
- In 7.3, the term "resistivity" has been replaced by "conductivity".
It has the status of a basic safety publication in accordance with IEC Guide 104.
The content of the corrigendum 1 (2026-02) has been included in this copy.

IEC 60112:2003+AMD1:2009 CSV(Main)

Method for the determination of the proof and the comparative tracking indices of solid insulating materials

IEC 60112:2003+A1:2009 Specifies the method of test for the determination of the proof and comparative tracking indices of solidinsulating materials on pieces taken from parts of equipment and on plaques of material using alternating voltages. The standard provides for the determination of erosion when required. Test results cannot be used directly for the evaluation of safe creepage distances when designing electrical apparatus. Has the status of a basic safety publication in accordance with IEC Guide 104. Major changes since the previous edition are the following: The selection of a material for a specific application frequently involves compromises in the levels of the individual properties and test criteria. In the previous edition of IEC 60112 the test criteria required "no burning of the specimen", but this gave rise to two issues:
- difficulties in the identification of burning which includes all types of combustion, e.g. flaming, and smouldering in the situation where scintillations had occurred giving rise in many cases to carbon on the surface of the specimen, and
- a situation in which some product committees had found it necessary to dispense with the "no burning" criterion in the tracking tests which they replaced by flame tests on the final product, thereby giving rise to two types of CTI/PTI with different criteria.
The contents of the corrigenda of June 2003 and October 2003 have been included in this copy. This consolidated version consists of the fourth edition (2003) and its amendment 1 (2009). Therefore, no need to order amendment in addition to this publication.

IEC 62676-6:2026(Main)

Video surveillance systems for use in security applications - Part 6: Performance testing and grading of real-time intelligent video content analysis devices and systems for use in video surveillance applications

IEC 62676-6:2026 specifies the functions, performance, interfaces, environmental adaptability, test methods, performance evaluation and grading rules of real-time intelligent video analysis in surveillance systems.
This document applies to live and forensic, real-time intelligent video analysis devices and systems in video surveillance.
The document is centred on testing performance and grading device functionality which enables:
• Core capability: Classification of objects, detection of specific "object activity", such as "stopping", "starting", "direction of movement", etc.
Examples are listed in Annex A.
• Complex capability: Detection of "scenarios" which are based on combinations of object activity, such as "loitering", "perimeter intrusion detection", "person down", "tailgating", "intrusion", "abandoned object detection", explosion, fire, flood, potential terrorist attack using a vehicle, owner of an abandoned bag, etc.
Examples of current scenarios are listed and described in Annex B.
• Degree of difficulty: The application of real operating environments to test the performance under known or required operating stress levels, examples of operating stress levels that are sterile or non-sterile, indoor or outdoor, target obscuration levels, extreme weather conditions, vibrating mechanical rugged environments causing image shake resulting in degradation of image quality requirement, see Table 1 and Annex C.
The purpose of this document is to provide end users, at different levels of the service process, from users and installers, integrators and maintenance companies, to certification providers, with methods to measure the performance of video analysis systems that must also comply with other parts of the standard.

IEC 60947-5-5:2026(Main)

Low-voltage switchgear and controlgear - Part 5-5: Control circuit devices and switching elements - Electrical emergency stop device with mechanical latching function

IEC 60947-5-5:2026 This edition includes the following significant technical changes with respect to the previous edition:
a) re-shaping the document with the clause numbers and names to be in line with other documents of the 60947 series;
b) review of the test method to reasonably determine that the latch mechanism meets the requirements of the document;
c) new Annex B for special requirements for illuminated push-button type emergency stop devices, including the reference to a function to distinguish between "active and inactive" by changing the colour of the push-button depending on the illumination.
This part of IEC 60947-5 provides detailed specifications relating to the electrical and mechanical construction of emergency stop devices with mechanical latching function and to their testing.
This document is applicable to electrical control circuit devices and switching elements which are used to initiate an emergency stop signal. Such devices can be provided with their own enclosure and will be installed according to the product documentation.
This document does not apply to:
– emergency stop devices for non-electrical control applications, for example hydraulic or pneumatic;
– emergency stop devices without mechanical latching function.
An emergency stop device conforming to this document can also be used as part of an emergency switching off means in compliance with IEC 60364-5-53.
NOTE See also IEC 60204-1:2016 and IEC 60204-1:2016/AMD1:2021, 9.2.3.4.
This document does not address specific requirements on acoustic noise as the noise emission of electrical emergency stop devices with mechanical latching function is not considered to be a relevant hazard.
This second edition cancels and replaces the first edition published in 1997. This edition constitutes a technical revision.
