Description (English):

IEC/TR 62368-2:2015(E) 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 62368-1:2014. This second edition cancels and replaces the first edition published in 2011. It constitutes a technical revision. This second edition updates the first edition of IEC 62368-2 published in 2011 to take into account changes made to IEC 62368-1:2010 as identified in the Forword of IEC 62368-1:2014. 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 62368-2:2015 (Explanatory information related to IEC 62368-1)

IEC TR 62368-2:2015 is an informative Technical Report published by the IEC that provides explanatory material and background rationale for IEC 62368-1 (the safety standard for audio/video, information and communication technology equipment). This second edition (2015) updates the 2011 TR to reflect changes made in IEC 62368-1:2014. It clarifies selected subclauses, explains intent and rationale, and helps readers interpret risk-based requirements - but it is informative only; if a conflict exists, IEC 62368-1 prevails.

Key topics and technical clarifications

Principles of the product safety standard: Explains the standard’s risk-reduction philosophy and the priority of measures (inherently safe design, safeguards, then information to users).
Hierarchy of safeguards: Maps ISO/IEC Guide 51 principles to IEC 62368-1 terms (e.g., class‑1 energy limiting, equipment and installation safeguards, behavioral/instructional safeguards).
Service and skilled-person considerations: Clarifies when equipment safeguards are required during maintenance or servicing to protect skilled persons from involuntary reactions or nearby class‑3 energy sources.
Normative references and transition guidance: Discusses how referenced documents are to be used and the importance of transition periods for adoption by test houses and manufacturers.
Terms and definitions: Provides rationale for modified or clarified definitions (for example, use of the term “safeguard” instead of “protection”; refinements to insulation, restricted access area, instructed/skilled person and reasonably foreseeable misuse).
Scope boundaries: Notes exclusions such as functional safety (covered by IEC 61508) and clarifies applicability to computers that may control safety systems.

Practical applications - who uses IEC TR 62368-2

Manufacturers and product designers - to understand the rationale behind IEC 62368-1 requirements and apply appropriate design safeguards for A/V and ICT equipment.
Compliance and test houses - for consistent interpretation of clauses and guidance on normative references and transition timing.
Safety engineers and technical authors - to draft instructions, service policies and safeguard implementations aligned with the standard’s intent.
Certification bodies and regulators - to interpret informative guidance while relying on the normative IEC 62368-1 for certification decisions.
