GOST 1461-2023 PDF

Full title and description

GOST 1461-2023 — "Petroleum and petroleum products. Method of ash test" (Russian: «Нефть и нефтепродукты. Метод определения зольности»). The standard establishes a laboratory method for determination of ash content in crude oil and petroleum products, including required apparatus, reagents, sampling, test procedure, calculation and precision limits; it specifies a detection range down to about 0.002% and lists product types to which the method does not apply (for example certain cokes, bitumens, used oils and products containing graphite, molybdenum disulfide, metallic dust or elemental sulfur).

Abstract

This interstate (GOST) standard defines the principle and procedural steps for gravimetric determination of ash in petroleum and related products: sampling and sample preparation; required laboratory glassware, crucibles and reagents; ignition/ashification procedure; mass calculations and expression of results; and repeatability/reproducibility (precision) criteria for reported values. The document includes normative references to other GOSTs that specify sampling, reagents and equipment.

Scope

Applies to crude oil and petroleum products for which ash determination by the specified gravimetric method is appropriate. Establishes the minimum measurable ash content (around 0.002%) and excludes several material classes (e.g., petroleum cokes, certain bitumens, used oils and additives/greases containing graphite, MoS2, metallic dust or elemental sulfur). The standard is intended for laboratory quality control, research and regulatory verification of ash content in applicable petroleum streams.

Key topics and requirements

• Principle of gravimetric ash determination (ignition/ashing and mass balance calculation).
• Requirements for apparatus, crucibles, glassware and temperature control for ignition.
• Reagents and purity requirements (e.g., acids, solvents, distilled water) used during preparation and cleaning.
• Sampling and sample preparation procedures (references to sampling standards).
• Test procedure steps, calculations, expression of results and reporting format.
• Precision: repeatability and reproducibility criteria and limits of detection (method performance around 0.002% ash).
• Explicit exclusions and notes on materials for which the method is not applicable.

Typical use and users

Used by chemical and petroleum testing laboratories, refinery and terminal quality-control personnel, producers and traders of petroleum products, certification bodies and regulatory agencies performing compliance testing, and by research organizations validating product compositions. Laboratories apply the method for routine QC, specification verification and troubleshooting when particulate or inorganic residues are of concern.

Related standards

The standard cites and/or is used together with other petroleum and laboratory standards such as GOST 2517 (sampling), GOST 3118 (hydrochloric acid), GOST 5789 (toluene), GOST 6709/related water standards, GOST 14710 (petroleum toluene), and standards for laboratory glassware and thermometers. It formally replaces GOST 1461‑75 and may be referenced by product specifications (jet fuels, lubricants, transformer oils etc.).

FAQ

Q: What is this standard?

A: An interstate (GOST) standard that specifies a laboratory method for determination of ash (inorganic residue) in crude oil and petroleum products — formally published as GOST 1461‑2023.

Q: What does it cover?

A: The standard covers sampling references, apparatus and reagents, sample preparation and the ignition/ashification procedure, calculations, precision (repeatability/reproducibility) and reporting. It sets the method's measurement capability (down to ~0.002%) and lists materials excluded from its scope.

Q: Who typically uses it?

A: Routine and contract testing laboratories, refinery QC teams, producers and traders of petroleum products, conformity assessment bodies and regulators.

Q: Is it current or superseded?

A: Current and in force. GOST 1461‑2023 was approved by Rosstandart by order No. 498‑ст (10 July 2023) and introduced for use in the Russian Federation from 1 July 2024 (with permission for earlier application). It replaces the earlier GOST 1461‑75; subsequent corrections/amendments (popravki) have been published.

Q: Is it part of a series?

A: It forms part of the family of standards on petroleum and petroleum products (ICS 75.080) and is referenced alongside other GOSTs covering sampling, reagents and laboratory equipment; it is not a serial-numbered 'part' of a single multi‑part document but is one of many GOSTs for petroleum testing methods.

Q: What are the key keywords?

A: Ash, ash content, zolnost, petroleum testing, gravimetric determination, crude oil, petroleum products, GOST 1461‑2023, Rosstandart, 75.080.
