GOST 33012-2014 PDF

Full title and description

GOST 33012-2014 — "Пропан и бутан товарные. Определение углеводородного состава методом газовой хроматографии" (English: "Commercial propane and butane. Determination of hydrocarbons by gas chromatography method").

This interstate (GOST) standard specifies the chromatographic method(s) used to determine the hydrocarbon composition of commercial propane and butane (LPG) samples.

Abstract

GOST 33012-2014 defines procedures for sampling, chromatographic analysis and calculation/reporting of hydrocarbon components in commercial propane and butane. The standard is a national/adopted modification of ISO 7941:1988 and includes additional safety requirements, expanded guidance on use of capillary columns, and an appendix for determination of detector sensitivity coefficients. It is intended for quality control and regulatory testing of liquefied petroleum gases (LPG).

General information

• Status: Active / in force.
• Publication date: Designated 2014; introduced into force as a national/interstate standard 1 January 2016 (registration/approval steps in 2014–2015).
• Publisher: Adopted as an interstate GOST (Interstate Council on Standardization, Metrology and Certification) and introduced nationally via Rosstandart; published copies distributed by standard publishers (e.g., Standartinform / commercial standards vendors).
• ICS / categories: MКС (ICS) 75.160.30 — Gaseous fuels / LPG (Russian classifier also shows 75.160.30).
• Edition / version: GOST 33012-2014 (first adoption; marked MOD in relation to ISO 7941:1988 due to national additions).
• Number of pages: 36 pages (typical published text length reported by standards resellers/databases).

Scope

The standard applies to commercial propane and commercial butane (LPG) and prescribes gas-chromatographic methods for quantitative determination of their hydrocarbon composition. It covers requirements for sampling, preparation of standards, chromatographic conditions, detectors and calculation of component concentrations and includes mandatory safety provisions for working with liquefied hydrocarbon gases and carrier gases such as hydrogen. The document is a modified adoption of ISO 7941:1988, with national additions (extra sections and an appendix) to reflect regional practice and safety rules.

Key topics and requirements

• Gas-chromatographic analysis procedures for LPG hydrocarbon mixtures (sample handling, column selection, operating conditions).
• Use of capillary columns and related chromatographic options (national additions provide guidance on capillary column use).
• Detector guidance and relative sensitivity (tables of relative molar/sensitivity correction coefficients for detectors such as thermal-conductivity detectors with H2 or He carrier gases are included).
• Calibration and use of certified reference LPG mixtures (GSO/SU samples) and procedures for determining detector sensitivity coefficients (Appendix A).
• Safety requirements for sampling, handling and chromatographic analysis of flammable liquefied gases and for using hydrogen as a carrier gas.
• Requirements for calculation, expression and reporting of component concentrations in mass or molar fractions according to the method.

Typical use and users

Primary users are analytical and quality-control laboratories in the petroleum and gas sector, LPG producers and distributors, regulatory bodies performing conformity assessment, research institutes, and plant QA/QC departments (the standard was prepared with input from Gazprom and associated research institutes). It is used for routine composition checks, specification verification, trade quality control and regulatory compliance testing across jurisdictions that adopt or reference the GOST.

Related standards

The standard is explicitly related to and based on ISO 7941:1988 (Commercial propane and butane — analysis by gas chromatography). It also sits alongside other LPG and petroleum product standards (for example, national GOST references listed in the normative bibliography and related ISO documents for LPG specifications and testing). Users typically consult ISO 9162 (LPG specifications), related national GOSTs cited in the normative references, and measurement/safety standards referenced within the text.

FAQ

Q: What is this standard?

A: GOST 33012-2014 is an interstate (GOST) analytical standard specifying gas‑chromatographic methods for determining the hydrocarbon composition of commercial propane and butane (LPG).

Q: What does it cover?

A: It covers sampling, chromatographic method parameters (including use of capillary columns), detector considerations and calibration/reporting procedures, plus safety requirements for handling LPG and carrier gases during analysis.

Q: Who typically uses it?

A: Analytical QC laboratories, LPG producers and distributors, regulatory testing bodies and research organizations in the oil & gas sector; the standard was prepared with participation from Gazprom and associated institutes.

Q: Is it current or superseded?

A: The standard was designated in 2014 and introduced into force on 1 January 2016. Major standards databases and national registries list it as active/in force; users should check national registries for any later amendments or replacements before relying on the method for regulatory compliance.

Q: Is it part of a series?

A: It is a standalone analytical method for commercial propane and butane but is related to broader families of petroleum product and LPG standards (ISO and national GOST series covering LPG specifications, sampling and testing methods). The standard notes its relationship to ISO 7941:1988 and cites multiple normative GOST/ISO references.

Q: What are the key keywords?

A: Propane, butane, LPG, gas chromatography, hydrocarbon composition, capillary column, thermal conductivity detector, calibration, sampling, ISO 7941.
