Description (English):

IEC TR 62368-2:2019 provides explanatory information related to IEC 62368-1. Only those subclauses considered to need further background reference information or explanation of their content to benefit the reader are included. Therefore, not all numbered subclauses are cited. Unless otherwise noted, all references are to clauses, subclauses, annexes, figures or tables located in IEC 62368-1:2018. This third edition updates the second edition of IEC 62368-2 published in 2014 to take into account changes made to IEC 62368-1:2014 as identified in the Foreword of IEC 62368-1:2018. This Technical Report is informative only. In case of a conflict between IEC 62368-1 and IEC TR 62368-2, the requirements in IEC 62368-1 prevail over this Technical Report. Key words: Audio/Video, Safeguards, Information, Communication

Abstract

Overview

IEC TR 62368-2:2019 is an informative Technical Report published by the IEC that provides explanatory information and background guidance for the safety standard IEC 62368-1:2018. It is the third edition, updating the 2014 TR to reflect changes in the 2018 edition of IEC 62368-1. IEC TR 62368-2 does not add requirements; where a conflict exists, the mandatory requirements in IEC 62368-1 prevail. The report targets Audio/Video, Information and Communication Technology (AV/ICT) equipment and explains the intent and application of selected clauses to help users implement the hazard-based approach in IEC 62368-1.

Key Topics and Technical Guidance

The Technical Report focuses on subclauses that benefit from additional background or explanation and includes informative material on:

Hazard-based safety engineering (HBSE) concepts and risk-reduction principles (illustrations and flowcharts).
Electrically-caused injury: explanations of shock, touch-current, insulation, clearances and protective bonding.
Electrically-caused fire: prevention, ignition likelihood reduction, and fire spread control; material flammability considerations.
Hazardous substances: assessment and control measures for chemical risks.
Mechanical hazards: safeguards against moving parts, structural strength and impact tests.
Thermal burn and radiation risks: evaluation of hot surfaces, heating elements, optical and UV radiation.
Test methods and examples: normal/abnormal/single-fault tests, test generators, and practical measurement guidance.
Annex guidance: detailed informative annexes covering examples of equipment in scope, component considerations, battery protection, clearances/creepage measurement, fire resistance tests, mechanical strength tests, and instructions/markings.

Practical Applications - Who Uses This Standard

IEC TR 62368-2 is useful for:

Product safety engineers and designers of audio/video and ICT equipment seeking interpretive guidance for IEC 62368-1.
Test laboratories and compliance teams using the TR to understand test intent and examples.
Regulatory authorities and certification bodies reviewing manufacturer documentation.
Technical writers and training organizations preparing user instructions and safety documentation.
Manufacturers implementing safeguards (electrical, thermal, mechanical, fire and chemical) and selecting appropriate test criteria.

Related Standards (if applicable)

IEC 62368-1:2018 - normative standard for AV/ICT safety (requirements take precedence).
References in the TR include other IEC/ISO guidance (e.g., IEC/TS 60479-1 on effects of current) and national/regional implementation documents where applicable.

Keywords: IEC TR 62368-2, IEC 62368-1, Audio/Video, Information and Communication Technology, safeguards, product safety, electrical safety, fire safety, battery protection.
