GOST R 52050-2020 PDF

Full title and description

GOST R 52050-2020 — "Топливо авиационное для газотурбинных двигателей ДЖЕТ А-1 (Jet A-1). Технические условия" (English title: Aviation turbine fuel Jet A-1. Specifications). National standard that establishes technical requirements, test parameters and related rules for Jet A‑1 aviation turbine kerosene intended for use in gas‑turbine engines of civil aircraft.

Abstract

This standard specifies the composition, essential physical and chemical properties, quality limits, test and sampling requirements, marking, packaging, storage and safety provisions for Jet A‑1 aviation turbine fuel supplied for civil aviation. It updates and replaces earlier national GOST R editions for Jet A‑1 and aligns many test-method references with ISO/IEC and GOST/ISO test procedures while retaining national requirements where applicable.

General information

• Publication date: 2020 (approved 1 October 2020; printed/publication references show 2020).
• Publisher: Federal Agency on Technical Regulating and Metrology (Rosstandart). Official printed edition commonly published by Standartinform (Moscow), 2020.
• ICS / categories: ICS 75 — Extraction and processing of oil, gas and related products; subgroup 75.160 (Fuel) — liquid fuel (commonly referenced as 75.160.20 Liquid fuel).
• Edition / version: GOST R 52050‑2020 (first edition under this designation; replaces GOST R 52050‑2006).
• Number of pages: Approximately 19–20 pages (varies slightly by publisher/translation and print layout).

Scope

Applies to Jet A‑1 aviation turbine fuel intended for use in civil aircraft gas‑turbine engines. The standard sets limits and test procedures for fuel parameters that affect operational safety, engine performance and handling (for example freezing point, flash point, distillation characteristics, density, sulfur and aromatics content, thermal/oxidative stability, water tolerance, conductivity, particulate content and deposits). It covers sampling, conformity assessment of batches, marking, storage, packaging and transport conditions, and allowable additives. NOTE: The Rosstandart approval order (No. 727‑ст of 1 Oct 2020) specified an initial introduction schedule that has been revised by later administrative orders; the standard’s planned entry date was moved by subsequent Rosstandart amendments (orders dated 29 Apr 2021, 21 Jun 2022, 27 Jun 2023 and an amendment of 10 Jun 2024) — the most recent official postponement set the date of introduction to 1 October 2026. Users should confirm the current legal (in‑force) status with Rosstandart or an official national registry before relying on mandatory applicability.

Key topics and requirements

• Designation and scope: definition of Jet A‑1 fuel and intended applications in civil aviation.
• Fuel composition and permitted additives: allowable antioxidant/anti‑static additives and limits for blending components.
• Physical properties and quality limits: freezing point, flash point, density/relative density, distillation fractions and volatility.
• Chemical limits: total sulfur, mercaptan sulfur, aromatic and naphthalene content, acid number.
• Performance and compatibility parameters: heat of combustion, lubricity (wear scar), thermal/oxidation stability, filterability and deposit formation limits.
• Contamination and water tolerance: limits for particulate contamination, free and emulsified water, and methods for assessing phase separation.
• Electrical conductivity: specified ranges for fuel with and without anti‑static additive.
• Sampling and test methods: references to GOST/ISO test methods for sampling, distillation, flash point, density, conductivity and other procedures.
• Marking, packaging, storage and transport: labeling requirements, container types, storage conditions and shelf‑life considerations to ensure fuel integrity.
• Safety, environmental and occupational provisions: handling precautions, personal protective equipment and measures to prevent environmental release.

Typical use and users

Used by fuel producers, refineries, aviation fuel blenders, quality laboratories, airport fuel farms and suppliers, aircraft operators, maintenance organisations, regulatory bodies and certification/inspection authorities. The standard is referenced by procurement and quality assurance teams, fuel testing laboratories and engineers responsible for fuel specification compliance and safe handling of aviation fuels.

FAQ

Q: What is this standard?

A: GOST R 52050‑2020 is the Russian national standard that defines technical requirements, test methods and handling/marking requirements for Jet A‑1 aviation turbine fuel intended for civil aircraft.

Q: What does it cover?

A: It covers fuel composition and allowable additives, physical and chemical property limits (freezing point, flash point, density, sulfur, aromatics, etc.), performance parameters (thermal stability, lubricity, deposits), sampling and laboratory test methods, packaging, storage/transport conditions and safety provisions.

Q: Who typically uses it?

A: Fuel producers, blenders, airport fuel suppliers and storage operators, aircraft operators, fuel testing laboratories, certification and inspection bodies, and regulatory authorities involved in aviation fuel quality and safety.

Q: Is it current or superseded?

A: GOST R 52050‑2020 was approved by Rosstandart (Order No. 727‑ст dated 1 October 2020) and replaces the 2006 edition. Its formal date of introduction has been revised multiple times by subsequent Rosstandart orders; the most recent administrative amendment set the planned entry‑into‑force date to 1 October 2026. As a result, depending on the latest official registry updates, the standard may be approved but its mandatory applicability date has been postponed — verify the current in‑force status with Rosstandart or an official national standards registry before assuming legal applicability.

Q: Is it part of a series?

A: It is a national GOST R standard in the family of fuel and petroleum product standards and replaces previous national editions for Jet A‑1. It also references and aligns with related GOST/ISO test method standards; it is not a multi‑part series under the same designation but sits alongside other petroleum product GOSTs.

Q: What are the key keywords?

A: Jet A‑1, aviation turbine fuel, kerosene, specifications, GOST R, Rosstandart, freezing point, flash point, sulfur, distillation, thermal stability, conductivity, sampling, test methods.
