IEC 60671:2007

IEC 60671:2007 defines the technical basis for surveillance testing of instrumentation and control systems important to safety in nuclear power plants. For organizations responsible for engineering review, compliance preparation, or procurement, IEC 60671:2007 is a focused reference for understanding how ongoing testing supports safety-related operation and documented evaluation. It is especially relevant where verification activities, operational consistency, and risk management must be aligned with plant safety requirements and controlled testing workflows.

What is IEC 60671:2007?

This document addresses surveillance testing for safety-important instrumentation and control systems used in nuclear power plant environments. In practice, it provides a compliance reference for planning and assessing testing arrangements that help confirm the continued technical performance of safety-related functions. IEC 60671:2007 is typically used during technical review, engineering documentation preparation, and conformity assessment work where the testing approach must be justified, traceable, and consistent with safety expectations.

Applications of IEC 60671:2007

IEC 60671:2007 is relevant to nuclear plant operators, system engineers, test teams, and assurance functions involved in surveillance testing programs. It may support evaluation of control and instrumentation equipment, verification planning, and maintenance-related testing within safety-critical systems. The document is also useful in procurement and supplier qualification workflows when testing obligations and documentation requirements need to be understood before deployment, acceptance, or ongoing service activities.

Why is IEC 60671:2007 important?

Surveillance testing plays a direct role in maintaining safety, technical validation, and confidence in system performance over time. IEC 60671:2007 helps organizations approach these activities with greater consistency, supporting quality assurance, conformity assessment preparation, and regulatory preparation where evidence of controlled testing is required. It can reduce ambiguity in engineering assessment and help align internal procedures with the expectations for safety-important instrumentation and control systems.
