IEC 60507:2013 is applicable for the determination of the power frequency withstand characteristics of ceramic and glass insulators to be used outdoors and exposed to polluted atmospheres, on a.c. systems with the highest voltage of the system greater than 1 000 V. These tests are not directly applicable to polymeric insulators, to greased insulators or to special types of insulators (insulators with semiconducting glaze or covered with any organic insulating material). The object of this International Standard is to prescribe procedures for artificial pollution tests applicable to insulators for overhead lines, substations and traction lines and to bushings. It may also be applied to hollow insulators with suitable precautions to avoid internal flashover. In applying these procedures to apparatus incorporating hollow insulators, the relevant technical committees should consider their effect on any internal equipment and the special precautions which may be necessary. This edition includes the following significant technical changes with respect to the previous edition: a) Corrections and the addition of explanatory material; b) The addition of Clause 4.3.2 on atmospheric correction; c) The change of the upper limit of conductivity of water to 0.1 S/m; and d) The extension to UHV voltages.

IEC 61786-1:2013 provides guidance for measuring instruments used to measure the field strength of quasi-static magnetic and electric fields that have a frequency content in the range 1 Hz to 100 kHz and with DC magnetic fields to evaluate the exposure levels of the human body to these fields. Sources of fields include devices that operate at power frequencies and produce power frequency and power frequency harmonic fields, as well as devices that produce fields within the frequency range of this document, including devices that produce static fields, and the earth's static magnetic field. The magnitude ranges covered by this standard are 0,1 μT to 200 mT in AC (1 μT to 10 T in DC) and 1 V/m to 50 kV/m for magnetic fields and electric fields, respectively. When measurements outside this range are performed, most of the provisions of this standard will still apply, but special attention should be paid to specified uncertainty and calibration procedures. The first editions of IEC 61786-1 and IEC 61786-2 replace IEC 61786:1998. Part 1 deals with measuring instruments, and Part 2 deals with measurement procedures. The content of the standard was revised in order to give up-to-date and practical information to the user.
It has the status of a horizontal standard in accordance with IEC Guide 108.

IEC 60743:2013 applies to the terminology used to describe tools, devices, equipment and methods used in live working. It standardizes the name of tools, devices and equipment and permits their identification by providing definitions and illustrations. It contains some example illustrations. This third edition cancels and replaces the second edition, published in 2001, and its Amendment 1:2008.This edition constitutes a technical revision which includes the following significant technical changes with respect to the previous edition: the clause 2 has been simplified and refers directly to IEC 60050-651; some definitions have been moved to specific existing clauses. This new edition is complementary to IEC 60050-651. Different publications under the responsibility of TC 78 include terms and its definitions. IEC 60050-651 (IEV 651) provides precise, brief and correct definitions of internationally accepted concepts in the field of live working, and specifies the terms by which these defined concepts are known. Electropedia gives access to the terms and definitions of IEC 60050-651 (http://www.electropedia.org/). Each product standard gives definitions necessary for the understanding of certain terms used in a specific context. The IEC Glossary (http://std.iec.ch/glossary) gives on-line access to the information.

IEC 62264-2:2013 specifies generic interface content exchanged between manufacturing control functions and other enterprise functions. The interface considered is between Level 3 manufacturing systems and Level 4 business systems in the hierarchical model defined in IEC 62264-1. The goal is to reduce the risk, cost, and errors associated with implementing the interface. This second edition cancels and replaces the first edition published in 2004 and constitutes a technical revision. It includes the following technical:
- addition of object models for exchange information used in manufacturing operations management activities;
- displacement of the UML object models that were in IEC 62264-1:2003 into this standard so that the object models and the associated attribute tables were available in the same document;
- addition of the Hierarchy scope object definition to replace the Location attribute used in the previous edition;
- addition of a value type section to define the exchange of non-simple value types;
- definition of simple value types were defined using the ISO 15000-5.
