Описание (английский):

Provides mathematical expressions for reliability, availability, maintainability and maintenance support measures. - Non-repaired items and - repaired items with zero and non-zero time to restoration are considered separately in this standard.

Abstract

Overview

Key Topics

Reliability Metrics: Defines reliability and failure rates for non-repaired and repaired items, specifying instantaneous and mean failure rates, mean time to failure (MTTF), and mean time between failures (MTBF).
Availability Measures: Covers instantaneous and mean availability and unavailability, asymptotic availability, and mean uptime/downtime for repaired systems with restoration times.
Maintainability Parameters: Includes mathematical definitions for maintainability, mean repair rate, mean repair time (MRT), mean active corrective maintenance time (MACMT), and mean time to restoration (MTTR).
Maintenance Support Terms: Addresses administrative and logistic delays impacting maintenance, providing expressions for mean administrative delay (MAD) and mean logistic delay (MLD).
System Classification: Differentiates between non-repaired units, repaired items with zero restoration time, and repaired items with non-zero restoration time with dedicated mathematical treatments for each case.
Assumptions and Conditions: Lists general assumptions behind the models used, ensuring clarity in the application of expressions.
Glossary and Symbols: Provides an extensive glossary of symbols, abbreviations, and definitions to standardize communication.

Applications

IEC 61703:2001 serves as a foundational tool in various industries and engineering fields where the reliability, availability, and maintainability (RAM) of equipment and systems are critical. Typical applications include:

Electronic and Electrical Equipment Design: Enables engineers to model and predict equipment failure behavior, improving design robustness and lifecycle planning.
Maintenance Planning and Optimization: Helps maintenance teams calculate realistic downtime expectations, plan preventive maintenance schedules, and improve maintenance logistics.
System Safety and Risk Assessment: Provides quantitative measures to assess system reliability and availability for safety-critical applications.
Asset Management: Assists in evaluating asset performance and justifying investments in maintenance and support infrastructure.
Quality Assurance and Compliance: Ensures adherence to international standards in product testing and reliability reporting.
Software Reliability: Although primarily focused on hardware, the annexes include considerations for software dependability.

Related Standards

IEC 61703 complements and aligns with other IEC standards and international guidelines on dependability and RAM analysis:

IEC 61014 - Dependability Management
IEC 60300 series - Dependability management frameworks and guidelines
ISO 14224 - Collection and exchange of reliability and maintenance data for equipment
IEEE 1633 - Software reliability models and measures
MIL-STD-781 - Military standard for reliability and maintainability reporting

Practical Value

IEC 61703:2001 standardizes the mathematical foundations for expressing reliability, availability, and maintainability. This makes it indispensable for:

Achieving consistent and comparable RAM metrics across projects and organizations worldwide.
Facilitating communication between designers, maintenance engineers, quality managers, and operational staff using clear, standardized definitions.
Supporting rigorous quantitative analysis that underpins decision making in design improvements, maintenance investments, and risk management.
Enhancing overall system dependability by enabling precise performance evaluation and benchmarking.

Organizations implementing IEC 61703 benefit from a reliable, universally understood framework to model and improve system lifecycle performance, contributing to higher productivity, safety, and cost-effectiveness.
