Full title and description

GOST R 50.05.09-2018 — Система оценки соответствия в области использования атомной энергии. Оценка соответствия в форме контроля. Унифицированные методики. Капиллярный контроль. (English: Conformity assessment system for the use of nuclear energy. Conformity assessment in the form of control. Unified methods. Liquid (capillary) penetrant testing.) This standard defines unified procedures for liquid penetrant (capillary) non‑destructive examination of base metal, welds and deposited surfaces of equipment and piping used in nuclear energy facilities.

Abstract

GOST R 50.05.09-2018 establishes requirements and a unified methodology for performing liquid penetrant (capillary) testing within the conformity assessment system for use of atomic energy. It covers preparation, materials and consumables, inspection procedures, defect indication evaluation, acceptance criteria, records and reporting, and personnel/quality requirements as applied to components, welded joints and surfaced areas of nuclear installations.

• Publisher: Federal Agency for Technical Regulation and Metrology (Rosstandart). Developed by the State Corporation for Atomic Energy (Rosatom) and technical working groups.
• ICS / categories: ICS 27.120 — Atomic energy (classification: non‑destructive testing / NDT in nuclear power engineering).
• Edition / version: GOST R 50.05.09-2018 (first edition, 2018).
• Number of pages: 28 pages.

Scope

The standard applies to liquid penetrant (capillary) control of base metal, welded joints and weld overlays (deposited surfaces) of equipment and pipelines of nuclear power installations. It is intended for use within conformity assessment in the form of control and specifies methodologies tailored to the safety and regulatory requirements of the nuclear industry.

Key topics and requirements

• Definitions and terminology specific to liquid penetrant testing in the nuclear sector (aligned with unified NDT terminology standards).
• Requirements for materials and consumables: penetrants, developers, cleaners and solvents (types, properties, storage and traceability).
• Surface preparation and cleaning procedures before inspection to ensure reliable indications.
• Detailed step‑by‑step inspection procedures for various penetrant techniques (water‑washable, solvent‑removable, post‑emulsifiable, visible/fluorescent methods) as applicable to nuclear equipment.
• Lighting, environmental and process controls (illumination levels, temperatures, contamination control) required during examination.
• Criteria for indication evaluation, sizing and classification of detected discontinuities relevant to acceptance/rejection decisions for nuclear components.
• Record keeping, reporting format and documentation necessary for conformity assessment and regulatory traceability.
• Requirements for equipment calibration, control samples, periodic verification and technical quality assurance of examination processes.
• Personnel competence: qualification, certification and responsibilities of NDT personnel performing penetrant testing in the nuclear field (references to personnel standards).
• Safety, contamination control and radiation protection considerations when performing penetrant testing on items used in nuclear installations.

Typical use and users

This standard is used by nuclear power plant operator organizations, manufacturers and fabricators of nuclear equipment, NDT service laboratories, quality assurance and inspection departments, design organizations, and regulatory authorities responsible for conformity assessment and in‑service inspection of components and piping in atomic energy facilities.

Related standards

GOST R 50.05.09-2018 is part of the GOST R series for conformity assessment in the field of nuclear energy and is commonly used alongside related documents such as other GOST R 50.05.* unified NDT method standards (visual and dimensional control, ultrasonic control, leak tightness testing, etc.), GOST R 50.05.15-2018 (NDT — terms and definitions), GOST R 50.05.11-2018 (personnel performing NDT), and internationally recognized NDT standards (for example ISO 3452-1 for liquid penetrant testing). It is also applied together with national regulatory rules for nuclear equipment (for example PNAE requirements) and legacy GOST documents governing NDT practice.
