GOST R 54484-2011 PDF

Full title and description

GOST R 54484-2011 — "Газы углеводородные сжиженные. Методы определения углеводородного состава" (Liquefied hydrocarbon fuel gases. Methods for determination of hydrocarbon composition). The standard specifies gas‑chromatographic procedures for determining the composition (individual hydrocarbon components and methanol) of liquefied hydrocarbon gases (LPG) using laboratory and on‑line (stream) chromatographs.

Abstract

This national Russian standard sets out chromatographic methods (sample preparation, calibration, measurement and calculation) to quantify saturated and unsaturated hydrocarbon components (C1–C5 and higher where applicable) and methanol in liquefied hydrocarbon gases. It includes metrological requirements, uncertainty evaluation, acceptance criteria and recommendations for calibration standards and sampling cylinders used for LPG analysis.

General information

• Publication date: Approved by Rosstandart order dated 01 November 2011; date of entry into force 01 June 2012 (implementation date shown in registry).
• Publisher: Federal Agency on Technical Regulating and Metrology (Rosstandart) / National standards of the Russian Federation.
• ICS / categories: 75.160.30 (Gaseous fuels / liquefied hydrocarbon gases).
• Edition / version: Designation: GOST R 54484‑2011 (2011 edition); includes an official amendment published in 2013.
• Number of pages: Approximately 32–33 pages (published PDF length commonly listed as 32–33 pages in standard catalogs).

Scope

The standard applies to liquefied hydrocarbon gases under their own vapor pressure and establishes chromatographic analysis methods for determining the content of paraffinic and olefinic hydrocarbons and methanol in LPG samples. It covers both laboratory gas chromatographs and continuous/flow (on‑line) chromatographs, giving procedures for sampling, calibration (including reference gas mixtures), measurement sequences and quality/acceptance checks.

Key topics and requirements

• Gas chromatographic procedures for quantitative determination of individual hydrocarbons (C1–C5 and heavier where applicable) and methanol.
• Requirements for sample collection and use of specialized constant‑pressure sampling cylinders for LPG.
• Calibration methods using certified reference gas mixtures (GSO‑СУГ) and calculation of calibration coefficients.
• Precision, expanded uncertainty assessment (coverage factor k≈2) and permissible limits for measurement results.
• Acceptance criteria for sequential measurements, procedures for repeat measurements, and corrective actions when calibration/stability checks fail.
• Recommendations for control charts and ongoing monitoring of chromatograph stability and metrological characteristics.

Typical use and users

Used by analytical and process laboratories in refineries, gas processing plants, LPG bottlers, distributors and regulatory laboratories for product quality control, certification and calculation of physical properties (density, vapor pressure, calorific value). Also applied by equipment manufacturers, metrology services and technical committees involved in LPG testing and standardization.

Related standards

References and related documents include earlier and parallel national standards on LPG sampling and properties, safety standards and metrology documents (several ГОСТ/ГОСТ Р referenced in the text), and later consolidated/updated standards: notably GOST 10679‑2019 "Газы углеводородные сжиженные. Метод определения углеводородного состава" (a newer/revised standard covering LPG composition methods introduced in 2019/2020). International and industry methods with similar scope include ASTM D2163 and Energy Institute IP 473 (gas chromatography methods for LPG composition).

FAQ

Q: What is this standard?

A: GOST R 54484‑2011 is a Russian national standard that defines gas‑chromatographic methods to determine the hydrocarbon composition (and methanol content) of liquefied hydrocarbon gases (LPG) for laboratory and on‑line analysis.

Q: What does it cover?

A: It covers sampling recommendations, chromatographic measurement procedures, calibration using reference gas mixtures, data normalization, precision and uncertainty evaluation, acceptance criteria, and quality control measures for LPG composition analysis.

Q: Who typically uses it?

A: Analytical laboratories, refinery and gas‑processing quality control teams, LPG bottlers and distributors, regulatory/metrology bodies and equipment suppliers involved in LPG composition testing and reporting.

Q: Is it current or superseded?

A: GOST R 54484‑2011 was adopted in 2011 and entered into force in 2012 with at least one official amendment published in 2013. A later relevant national standard covering the same subject is GOST 10679‑2019 (introduced in 2019/2020), which provides an updated method for determination of LPG hydrocarbon composition; users should check the current national registry or Rosstandart notices to confirm which document is the operative normative reference for a specific application or regulatory requirement.

Q: Is it part of a series?

A: It belongs to the family of standards and normative documents addressing liquefied hydrocarbon gases (sampling, technical specifications, calculation methods and test methods). The document cross‑references and complements other ГОСТ/ГОСТ Р standards on LPG properties, sampling, safety and metrology.

Q: What are the key keywords?

A: Liquefied hydrocarbon gases (LPG), gas chromatography, hydrocarbon composition, calibration gas, methanol, measurement uncertainty, sampling cylinder, metrology.
