IEC 60050-428:2024

Overview

IEC 60050-428:2024, titled International Electrotechnical Vocabulary (IEV) – Part 428: Safety of Machinery, is a standardized reference developed and published by the International Electrotechnical Commission (IEC). This edition provides the general terminology related to the safety of machinery with a focus on electrotechnical aspects. As a horizontal publication under IEC Guide 108, it promotes consistent and harmonized use of terms across multiple standards in the field of machinery safety. The document supports international cooperation and understanding by offering terminology entries in several languages including English, French, Arabic, German, Spanish, Japanese, Korean, Polish, Portuguese, and Chinese.

Key Topics

IEC 60050-428:2024 is structured into multiple sections, each addressing specific areas of machinery safety terminology:

• General Terms (Section 428-01): Covers foundational definitions applicable across safety-related domains of machinery.
• Electrical Equipment (Section 428-02): Defines terms relating to electrical components and systems integrated into machinery.
• Electrical Safety (Section 428-03): Focuses on terminology connected to electrical hazards, protection measures, and compliance.
• Functional Safety (Section 428-04): Details key concepts related to safety functions, control systems, and failure management in electromechanical machinery.
• Electro-sensitive Protective Equipment (Section 428-05): Defines devices that detect or respond to electrical and movement-based signals for safety purposes.
• Safety-related Sensors (Section 428-06): Addresses sensor technology used for monitoring and mitigating risks in machinery operation.
• Security Aspects (Section 428-07): Deals with terminology associated with safeguarding machinery against unauthorized access or interference.

The vocabulary assists designers, manufacturers, and safety professionals by offering standardized definitions that align with existing provisions in other parts of the IEC 60050 series and related safety standards.

Applications

IEC 60050-428:2024 is essential for anyone involved in electrotechnical safety within industrial and manufacturing machinery environments. This includes:

• Machine manufacturers who require clear, internationally accepted terminology to develop safe, compliant products.
• Safety engineers and consultants tasked with risk assessment and implementation of safety measures in machinery.
• Regulatory bodies and standards developers seeking harmonization of safety terms to facilitate consistent legislation and guidance worldwide.
• Educational institutions and trainers delivering courses on machine safety and functional safety standards.
• Technical writers and translators who need authoritative terminologies in multiple languages for documentation and communication.

Using this IEC vocabulary ensures clarity, avoids misinterpretation, and supports interoperability between electrical safety systems and machinery components globally.

Related Standards

IEC 60050-428:2024 complements and aligns with several other IEC standards and guides, including:

• IEC Guide 108: Defines the status and application scope of horizontal publications like this vocabulary.
• Other parts of the IEC 60050 series: For example, IEC 60050-161 on electromagnetic compatibility or IEC 60050-411 on rotating machines, which offer related electrotechnical terminology.
• IEC 61508 series on Functional Safety: Providing deeper requirements and guidance on functional safety lifecycle management.
• ISO/IEC Directives Part 2: Ensures the vocabulary is developed in compliance with recognized international standardization procedures.

For convenient access, the IEC offers an online platform called Electropedia (www.electropedia.org), where users can explore the full multilingual electrotechnical vocabulary and stay updated with new terms and amendments.
