Full title and description

IEC/IEEE 62582-3:2012 — Nuclear power plants - Instrumentation and control important to safety - Electrical equipment condition monitoring methods - Part 3: Elongation at break. This dual-logo international standard specifies tensile elongation (elongation at break) test methods, sample selection, measurement-system requirements, test conditions and reporting formats for condition monitoring of organic and polymeric materials used in instrumentation and control equipment important to safety in nuclear power plants.

Abstract

This part of IEC/IEEE 62582 defines a reproducible elongation-at-break measurement method for polymeric materials (thermoplastics and elastomers) taken from equipment or cables used in nuclear I&C systems. It is intended to support ageing management and qualification by providing detailed procedures for specimen preparation, tensile testing, data recording and reporting so that changes in mechanical properties can be tracked and compared against acceptance criteria.

Scope

This part of IEC/IEEE 62582 covers the tensile elongation (elongation at break) technique used for condition monitoring of polymeric materials in instrumentation and control equipment important to safety in nuclear power plants. It specifies: selection and preparation of specimens (including dimensions and sample extraction from cables or components), test apparatus and calibration, test speed and environmental conditions, measurement procedures, calculation of elongation at break, and format for reporting results. The method is intended for non‑energized equipment and for use in ageing-management programs and qualification activities.

Key topics and requirements

• Definition of specimen geometry and preparation from in‑service equipment or cable samples.
• Requirements for tensile test apparatus, grips, and calibration to ensure reproducible elongation-at-break data.
• Specified test speeds, temperature and conditioning procedures to control test environment.
• Procedures for determining elongation at break and related calculations (strain measurement and reporting conventions).
• Acceptance of data formats and recommended reporting templates to support trending and qualification records.
• Applicability guidance for different polymer types (thermoplastics and elastomers) and limitations of the technique.

These topics are described to produce accurate, reproducible measurements that support ageing management and qualification decisions for safety-important I&C electrical equipment.

Typical use and users

Primary users are nuclear power plant instrumentation & control engineers, ageing‑management and equipment‑qualification specialists, test laboratories performing condition monitoring, component and cable manufacturers supporting qualification, and regulatory bodies reviewing qualification and surveillance programs. The standard is used to obtain comparable tensile property data for baseline qualification, post‑installation monitoring and investigation of suspected material degradation.
