IEC Guide 104:2019(E) is mandatory and defines procedures for the preparation of safety publications in addition to ISO/IEC Guide 51, including the preparation and use of basic safety publications and group safety publications. Also describes the relationship between TCs with horizontal safety functions or group safety functions and product TCs. In the context of this guide, "safety" relates to the safety of persons, domestic animals, livestock and property. The main changes with respect to the previous edition are as follows:
- alignment with terms and definitions of ISO/IEC Guide 51:2014;
- reference to IEC Guide 108 in the introduction;
- creation of BASIC SAFETY PUBLICATION and GROUP SAFETY PUBLICATION subcategories to clarify the different types of document (requirements, guidance, mandatory test procedures and reference data);
- improved structure: new titles and subclauses;
- addition to the responsibilities of the technical committees (TCs) with HORIZONTAL SAFETY FUNCTION: development of their publications in collaboration with customer TCs and monitoring the use of their SAFETY publications;
- replacement of Annex A and the associated text by reference to IEC Guide 116;
- shortened status statement for publications with BASIC SAFETY PUBLICATION designation;
- addition of the scope items of a PRODUCT SAFETY STANDARD.

IEC Guide 116:2018(E) is non-mandatory and complements ISO/IEC Guide 51 and establishes guidelines useful for achieving safety in low voltage equipment. These guidelines include risk assessment, in which the knowledge and experience of the design, use, incidents, accidents and harm related to low voltage equipment are brought together in order to assess the risks during the relevant phases of the life of the equipment and to implement the basics for risk reduction measures. This IEC guide should be used by technical committees as far as appropriate and to the extent they decide to apply it. It gives additional guidance to ISO/IEC Guides 50, 51 and 71 on the information required to allow risk assessment to be carried out performed.
This second edition of IEC Guide 116 cancels and replaces its first edition published in 2010 and constitutes a technical revision; main changes with respect to the first edition are as follows:
- addition of a clause dealing with safety related security aspects, derived from the IEC 62443 series;
- reference to “domestic animals” rather than to “livestock”;
- alignment of definitions and Figure 2 with the latest edition of ISO/IEC Guide 51 (2014);

IEC Guide 112:2017(E) contains guidelines for using the current editions of IEC 60065 and IEC 60950-1 in evaluating the safety of multimedia equipment. This Guide focuses on the use of IEC 60065 or IEC 60950-1. As an alternative to both standards, IEC 62368-1 may be used. This fourth edition includes the following significant technical changes with respect to the previous edition:
- it makes reference to the latest editions of IEC 60065 and IEC 60950-1;
- it deals additionally with equipment containing coin / button cell batteries.

IEC GUIDE 110:2014 provides background information to technical committees when dealing with safety requirements for products intended to be integrated in a home control system. It includes information on functional safety as well as conventional safety aspects relevant to home control systems. This Guide deals with home control systems providing control communication for equipment used within homes. This includes the control of equipment for cooling, heating, lighting, audio/video, telecommunications, security, etc., in fact, any equipment controlled by the home control system. It also includes residential gateways between the internal home control system network and external wide-area networks such as the internet. The main changes with respect to the previous edition are as follows:
- addition of several new electrical safety aspects;
- inclusion of cyber security;
- consistent use of the term "equipment" to replace terms such as "device", "system", "product", etc..

IEC Guide 117:2010(E) provides guidance for assessing the risk, to any person, of a burn from contact with hot touchable surfaces of electrotechnical equipment. Establishes surface temperature limits, where such limits are required, and describes the maximum contact periods with a hot surface that any person may be subjected to without being exposed to a risk of burn. Curves of maximum temperatures versus contact times are described for different types of material with different types of surfaces. These temperature limit values shall be taken into consideration by technical committees in determining surface temperature limits in product standards.

IEC Guide 104:2010(E) is mandatory and defines procedures for the preparation of safety publications in addition to ISO/IEC Guide 51, including the preparation and use of basic safety publications and group safety publications. Also describes the relationship between TCs with horizontal safety functions or group safety functions and product TCs. In the context of this guide, "safety" relates to the safety of persons, domestic animals, livestock and property. The main changes with respect to the previous edition are as follows:
- updates the third edition, in the light of experience, to align it with IEC Guide 108;
- includes a better description of the group safety function and group safety publications in subclause 5.1.3;
- includes a clarification in Annex A of measures in case of a single fault condition.
