GOST IEC 61619-2014 PDF

Full title and description

GOST IEC 61619-2014 — Insulating liquids. Determination of contamination by polychlorinated biphenyls (PCBs) by capillary column gas chromatography method. The document is the Russian national adoption of the IEC method for measuring PCB contamination in insulating (transformer) oils using high‑resolution capillary gas chromatography with an electron‑capture detector (ECD).

Abstract

This standard specifies a laboratory method to determine total PCB contamination and, where required, a more detailed congener analysis in non‑halogenated insulating liquids. It describes required reagents, apparatus, chromatographic conditions, sample preparation and reporting, and gives performance characteristics such as detection limits and precision for routine testing of new, used or regenerated insulating oils.

Scope

The standard applies to non‑halogenated insulating liquids and specifies a capillary‑column gas chromatography method with an electron‑capture detector (ECD) for the determination of PCB contamination. It is applicable to unused, used and regenerated insulating liquids (including chemically or physically treated products) when measurement of total PCB content or detailed congener analysis is required. The method gives instructions on sample handling, chromatographic conditions, instrumental checks, data processing, detection limits and precision.

Key topics and requirements

• Principle: high‑resolution capillary‑column gas chromatography with an electron‑capture detector (ECD) for PCB detection.
• Scope of application: non‑halogenated insulating liquids; suitable for new, used and regenerated oils.
• Sampling and sample preparation requirements (references to insulating liquid sampling standards where applicable).
• Required reagents, calibration mixtures and reference materials for total PCB and congener analysis.
• Chromatograph configuration and operating conditions (column type, temperature program, carrier gas, detector settings).
• Instrument performance checks, detection limit determination and procedures to verify precision and accuracy.
• Data processing, calculation of total PCB content and reporting requirements (including units and uncertainty statement).
• Notes on applicability and limitations (e.g., not for halogenated insulating liquids without modification).

Typical use and users

Analytical and environmental testing laboratories, transformer manufacturers and maintenance facilities, electrical utilities, petrochemical laboratories, regulatory and inspection bodies and consultants use this standard to assess PCB contamination in transformer and insulating oils for safety, environmental compliance and asset‑management decisions.

Related standards

Base standard: IEC 61619:1997 (Insulating liquids — contamination by PCBs — capillary GC method). Normative and related national documents include the GOST/GOST‑R adoptions of IEC 61619 and sampling standards for insulating liquids (for example, GOST R IEC 60475 series on sampling of insulating liquids). Users commonly consult regional/adopted versions (EN/IEC adoptions) and adjacent methods for PCB congener analysis and sampling practice.

FAQ

Q: What is this standard?

A: It is the Russian national adoption (GOST IEC 61619-2014) of the IEC method for determining PCB contamination in insulating liquids using capillary‑column gas chromatography with ECD.

Q: What does it cover?

A: The method covers sample preparation, chromatographic conditions, instrument performance checks, calculation of total PCB content (and optional congener analysis), detection limits, precision and reporting for non‑halogenated insulating liquids. It is suitable for new, used and regenerated oils.

Q: Who typically uses it?

A: Analytical/environmental laboratories, transformer OEMs and service organizations, electric utilities, regulators and consultants involved in oil testing and environmental compliance.

Q: Is it current or superseded?

A: The national GOST adoption (GOST IEC 61619-2014) is published and listed as active in national catalogs; the base IEC publication IEC 61619 (1997) remains the underlying international document. Users should check for any newer IEC revisions or project updates (IEC work on a newer edition is visible in standards development records) before assuming long‑term stability.

Q: Is it part of a series?

A: Yes — it belongs to the body of standards for insulating liquids and fluids for electrotechnical applications (TC 10). It is commonly used alongside sampling standards (e.g., national adoptions of IEC/GOST sampling standards) and other analytical methods for insulating oils.

Q: What are the key keywords?

A: Insulating liquids; PCB; polychlorinated biphenyls; capillary GC; ECD; transformer oil; contamination; analysis; GOST; IEC 61619.
