IEC 60050-192:2015 - International Electrotechnical Vocabulary (IEV) Part 192: Dependability
Overview
IEC 60050-192:2015 is an International Standard published by the International Electrotechnical Commission (IEC) that provides a comprehensive vocabulary of general terminology used in the field of dependability. This standard covers terms applicable to all dependability methodologies, including those specifically related to electrotechnical applications. It replaces certain sections of the earlier IEC 60050-191:1990 edition following a thorough review to reflect current practices and terminologies.
This horizontal standard aligns with IEC Guide 108 and supports uniform language usage to facilitate communication, standardization, and best practices across global industries focused on system reliability, availability, maintainability, and safety.
Key Topics
- Dependability Terminology: Defines fundamental terms and definitions essential for reliability engineering, safety assessment, risk management, fault tolerance, maintainability, and availability analysis.
- Generic Approach: The vocabulary is generic and applicable across different fields, promoting cross-sector understanding, though some specialized terms can be found in other IEC standards.
- Revision and Updates: Enhances practical relevance by including terms commonly used by professionals and introducing clarifying figures, especially for time-related dependability concepts.
- Multilingual Presentation: Terms provided in English and French, with additional translations available in nine languages including Arabic, German, Spanish, Japanese, and Chinese, supporting international accessibility.
- Standard Structure: Includes a comprehensive list of terms, definitions, and an informative annex relating previous editions for traceability and historical reference.
Applications
IEC 60050-192 serves as a foundational reference for:
- Electrical and Electronic Engineering: Ensures consistent dependability terminology in design, testing, and evaluation of electrical and electronic systems.
- Reliability Engineering: Helps engineers and quality assurance professionals apply common language and understanding when analyzing system reliability and maintenance.
- Safety and Risk Management: Provides precise definitions facilitating clearer communication in safety-related assessments and regulatory compliance documentation.
- Standardization and Research: Supports development of additional international standards and academic research by providing standardized definitions.
- Cross-industry Collaboration: Bridges terminology gaps across various sectors such as energy, transportation, manufacturing, and IT where dependability is critical.
Related Standards
- IEC 60050 Series: IEC 60050-192 is part of the broader International Electrotechnical Vocabulary series covering terminology across the electrical and electronic fields. Other parts detail terms for specific technologies and disciplines.
- IEC 60050-191: The preceding edition containing sections now replaced by IEC 60050-192, relevant for historical context and legacy systems.
- IEC Guide 108: Provides guidelines for horizontal standards, establishing how terminology and related standards should be consistently managed.
- ISO/IEC Directives Part 2: The standard was prepared in accordance with these directives, ensuring proper development methodology and editorial rules.
For professionals involved in dependability and reliability engineering, IEC 60050-192:2015 is an essential resource that promotes a common language and supports international standardization efforts. This vocabulary enhances accuracy in communication, documentation, and implementation of dependability principles critical to system safety and performance worldwide.
