IEC 61069-8:2016

IEC 61069-8:2016 Overview

IEC 61069-8:2016 is an international standard developed by the International Electrotechnical Commission (IEC) focused on the evaluation of other system properties for industrial-process measurement, control, and automation systems. This document is part 8 of the IEC 61069 series, which deals with the assessment of system properties to ensure reliable and efficient operation of basic control systems (BCS).

This 2016 edition is a technical revision of the original 1998 version. It reorganizes content for better consistency within the broader IEC 61069 framework and incorporates IEC TS 62603-1. The standard defines categorization of other system properties, identifies influencing factors, and proposes methodologies and techniques for system property assessment.

Key Topics

• Other System Properties (OSP): The standard expands on non-task-related properties beyond core system functions, covering:

  • Quality assurance
  • System support
  • Compatibility
  • Physical properties

• Assessment Methodology:

  • Clear definition of assessment objectives
  • Design and planning of assessment programs
  • Execution and reporting procedures ensuring systematic evaluation

• Evaluation Techniques:

  • Analytical methods for quality, support, compatibility, and physical aspects
  • Empirical techniques to provide practical validation of system properties
  • Guidance to select the most appropriate evaluation tools and indicators

• Influencing Factors: Identification of critical factors impacting system properties is key for accurate assessment, including technical, operational, and environmental variables.

• Supporting Documentation: Includes checklists, system requirement documentation (SRD), system specification documents (SSD), and evaluation matrices to facilitate structured assessments.

Applications

IEC 61069-8:2016 is primarily designed for use in industrial environments where measurement and automation control systems are critical. Its applications include:

• System Assessment: Ensuring basic control systems meet comprehensive performance and reliability requirements through detailed evaluation of auxiliary system properties.
• Quality Management: Supporting quality assurance processes by evaluating production, delivery, and development aspects related to system suppliers and technologies.
• Vendor and Product Selection: Assists in evaluating compatibility and support services offered by vendors, including training, technical support, and documentation.
• Process Optimization: Helps identify weaknesses in system support and maintenance frameworks to enhance operational continuity and efficiency.
• Risk Management: By thoroughly assessing physical and support properties, the standard aids in minimizing operational risks associated with control systems.

Related Standards

IEC 61069-8:2016 forms part of a comprehensive family of standards under IEC 61069, which addresses system property evaluation for control systems:

• IEC 61069-1: Basic concepts and terminology for system property evaluation.
• IEC 61069-2: Methodology for system property assessment.
• IEC TS 62603-1: Incorporated technical specification related to non-task-related system properties evaluation.

Additional related IEC documents supporting industrial automation and control systems include:

• IEC 61508: Functional safety of electrical/electronic systems.
• IEC 61131: Programmable controllers.
• IEC 62443: Security for industrial automation and control systems.

By providing a structured, standardized approach to evaluating supplementary system properties beyond basic task functions, IEC 61069-8:2016 plays a vital role in enhancing industrial system reliability, compatibility, and maintainability. Compliance with this standard enables engineers and organizations to optimize control system performance while managing quality and support effectively.
