GOST 34396-2018 PDF

Full title and description

GOST 34396-2018 — "Oil and oil products custody transfer metering systems. General specifications" (Russian: "Системы измерений количества и показателей качества нефти и нефтепродуктов. Общие технические условия"). This interstate GOST establishes general technical requirements for systems used to measure quantity and quality indicators of crude oil and petroleum products for custody transfer and commercial accounting.

Abstract

This standard sets out general technical conditions, metrological requirements and functional provisions for custody transfer metering systems for oil and oil products. It covers the purpose and structure of measurement systems, required metrological characteristics and accuracy classes, guidelines for installation, calibration/verification, sampling and quality-parameter measurement, data recording and reporting necessary for commercial (custody transfer) operations.

Scope

Applies to measurement systems designed for custody transfer of crude oil and petroleum products, including both quantity (volume/mass) and quality indicators. The standard addresses system components (meters, sampling devices, density/temperature compensation, data acquisition and transmission), metrological characteristics and verification/calibration procedures required to ensure accurate commercial accounting. It is intended for use where reliable measurement and recording are required for commercial transactions and regulatory reporting.

Key topics and requirements

• Definitions and classification of custody transfer metering systems (functional architecture and components).
• Metrological requirements: accuracy classes, allowable measurement uncertainty, and calibration/verification intervals.
• Instrumentation and installation rules: flow meters, density/temperature sensors, sampling systems and data acquisition hardware.
• Sampling and quality-parameter measurement procedures (samples for laboratory analysis; quality indicators used in custody transfer).
• Data recording, processing and reporting: secure logging, audit trail, and protocols for transmitting measurement results for commercial settlement.
• Requirements for environmental and safety considerations and for routine maintenance and functional checks.

Typical use and users

Used by oil producers, pipeline and terminal operators, refinery and trading companies, metrology laboratories, system integrators and regulators involved in custody transfer, commercial accounting and regulatory compliance for oil and petroleum products. It guides engineers, metrologists and procurement teams specifying, installing and maintaining custody transfer metering systems.

Related standards

Frequently referenced standards include national GOSTs and sectoral metrology documents dealing with sampling, density and mass determination, and measurement procedures — for example GOST 8.587 (methods for measurement of oil mass and petroleum products), standards on sampling and density determination and other GOSTs for petroleum product testing and metrology. The GOST forms part of a suite of standards governing pipeline and custody-transfer systems.
