IEC 61069-2:2016

Overview

IEC 61069-2:2016 is an International Electrotechnical Commission (IEC) standard that provides a comprehensive assessment methodology for evaluating basic control systems (BCS) in industrial-process measurement, control, and automation. Building on the fundamental concepts introduced in IEC 61069-1, this second edition presents a reorganized and updated framework for analyzing and weighing system properties and influencing factors to develop effective assessment programs.

This standard, updated from its 1993 predecessor and incorporating IEC TS 62603-1:2014, focuses on providing stakeholders with a structured method to assess the performance, reliability, and functionality of control systems critical to industrial automation processes.

Key Topics

• Assessment Approach: A procedural framework for defining objectives, planning, and executing system assessments.
• System Properties and Influencing Factors: Identification and evaluation of critical system attributes influencing control system performance.
• Assessment Phases: Clear delineation of phases including scope definition, documentation collation, selection of assessment items, program planning, execution, and reporting.
• Documentation and Collation: Guidelines for compiling detailed system information that supports accurate assessment.
• Evaluation Techniques: Methods to systematically analyze assessment data to derive meaningful insights on system capabilities.
• Supporting Annexes:
  • System Requirements Document (SRD) development and analysis
  • System Specification Document (SSD) preparation
  • Practical examples of collation documentation for varied control tasks

Applications

IEC 61069-2:2016 is essential for organizations involved in industrial automation, especially those designing, implementing, or managing basic control systems in sectors such as manufacturing, energy, chemical processing, and utilities. Key applications include:

• System Assessment and Verification: Ensuring control systems meet required functional and performance specifications.
• Risk and Reliability Analysis: Evaluating system dependability and identifying potential failure points before deployment.
• Compliance and Quality Assurance: Aligning with international best practices for system evaluation to support certification and market acceptance.
• System Development Lifecycle Support: Informing design reviews and validation phases through structured assessment methodologies.
• Optimization of Control Systems: Identifying areas for improvement by systematically assessing system properties and operational factors.

Related Standards

• IEC 61069-1: Fundamental concepts for evaluation of system properties, serving as the foundation for Part 2 assessment methodologies.
• IEC TS 62603-1:2014: Incorporated within IEC 61069-2:2016, providing additional technical specifications related to system assessment.
• Other IEC standards in industrial automation and control systems provide complementary guidance on measurement, control loops, and automation architectures.

Utilizing IEC 61069-2:2016 equips engineers, system integrators, and quality managers with a reliable, internationally accepted method to assess and improve complex control systems, enhancing safety, efficiency, and operational excellence in industrial settings.
