Full title and description
IEC 62887:2018 — Nuclear power plants - Instrumentation systems important to safety - Pressure transmitters: Characteristics and test methods. This International Standard specifies requirements and test methods for pressure transmitters used in instrumentation systems important to safety in nuclear power plants, covering design, materials, manufacture, testing, calibration and inspection for nuclear applications.
Abstract
IEC 62887:2018 sets out specific technical and qualification requirements for pressure transmitters when employed in safety‑related instrumentation of nuclear power plants (including PWR, BWR and FBR). The document addresses transmitter types and structures, selection criteria (including remote seals), measurement characteristics, environmental and ageing considerations, test and calibration methods, and inspection/documentation practices required to demonstrate suitability under nuclear conditions.

Scope
Applies to general aspects of design, manufacture and test methods for pressure transmitters used in instrumentation systems important to safety in nuclear power plants. The standard covers pressure‑measurement functions, transmitter structures and types (including devices with remote seals), selection and installation considerations, performance characteristics, and the qualification and testing measures necessary to ensure reliable operation under nuclear service and accident conditions.
Key topics and requirements
- Definitions, types and basic structure of pressure transmitters for nuclear use (including remote‑seal configurations).
- Design and material requirements to withstand nuclear environmental conditions and ageing.
- Performance characteristics: accuracy, range, response time, stability, drift and failure modes.
- Selection criteria for transmitter and remote‑seal combinations, including process‑interface considerations.
- Qualification, environmental and seismic testing requirements; calibration and inspection procedures.
- Documentation, marking, traceability and manufacturer quality / factory‑acceptance testing expectations.
- Guidance on ageing management and how ageing may affect qualified life and maintenance/calibration intervals.
These topics reflect the standard’s emphasis on demonstrating that transmitters perform their safety functions in both normal operation and specified design basis events.
Typical use and users
Used by transmitter manufacturers, qualification and design engineers, test laboratories, plant instrumentation engineers, safety assessors, regulatory authorities and procurement teams involved in nuclear power plant I&C (instrumentation & control) systems. Utilities and plant modification teams use the standard when specifying, qualifying or replacing pressure transmitters in safety‑related systems.
Related standards
Commonly used together with other nuclear I&C and equipment qualification standards such as IEC 61513 (general I&C system requirements), IEC/IEEE 60780‑323 (qualification of electrical equipment important to safety), IEC 62765‑1 (ageing management of pressure transmitters) and IEC 61226 (categorization/classification of I&C functions). These complementary standards address overall I&C life‑cycle, function classification, equipment qualification and ageing management that frame transmitter requirements in a nuclear context.
