Nuclear power plants - Instrumentation and control important to safety - Electrical equipment condition monitoring methods - Part 4: Oxidation induction techniques
IEC/IEEE 62582-4:2022 specifies methods for condition monitoring of organic and polymeric materials in instrumentation and control systems using oxidation induction techniques in the detail necessary to produce accurate and reproducible measurements. It includes the requirements for sample preparation, the measurement system and conditions, and the reporting of the measurement results. This second edition cancels and replaces the first edition published in 2011, and its Amendment 1:2016. This edition includes the following significant technical changes with respect to the previous edition: - Consideration of publication of IEC/IEEE 60780-323; - An example added in Annex B and update; - Annex C added.
IEC/IEEE 62582-4:2022 - "Nuclear power plants – Instrumentation and control important to safety – Electrical equipment condition monitoring methods – Part 4: Oxidation induction techniques" specifies standardized methods for condition monitoring of organic and polymeric materials used in safety-related instrumentation and control (I&C) systems. The standard defines the technical requirements needed to produce accurate, reproducible oxidation induction measurements (thermograms/heat-flow data) for assessing material ageing and antioxidant depletion. This second edition (2022) updates the 2011 edition, adds Annex C, and includes an example in Annex B; it also considers IEC/IEEE 60780-323.
The standard provides detailed, actionable requirements for oxidation induction testing, including:
IEC/IEEE 62582-4:2022 is intended for professionals involved in nuclear plant ageing management, condition monitoring and qualification programs:
