Overview
ISO 6246:2017/Amd 1:2019 is an important amendment to the international standard ISO 6246, which defines the methodology for determining the gum content in petroleum fuels using the jet evaporation method. This amendment specifically updates the purity requirements for the solvent n-heptane used in the testing process. The standard is maintained by ISO Technical Committee ISO/TC 28, which focuses on petroleum products and related materials, ensuring a globally recognized and consistent approach to fuel analysis.
This amendment mandates that the n-heptane solvent must have a minimum purity of 99%, optimizing the accuracy and reliability of gum content measurement in fuels. Gum content testing is critical for assessing fuel quality, influencing engine performance and fuel stability.
Key Topics
- Standard Reference: ISO 6246:2017/Amd 1:2019
- Title: Petroleum products - Gum content of fuels - Jet evaporation method - Amendment 1: Purity requirement for n-heptane
- Scope: Defines purity requirements for n-heptane used in the gum content jet evaporation test
- Purity Requirement: Minimum 99% pure n-heptane essential for reliable solvent performance
- Test Method: Jet evaporation method for quantifying gum content in fuels
- Organization: International Organization for Standardization (ISO)
- Technical Committee: ISO/TC 28 - Petroleum products and related products, fuels, and lubricants
- Document Status: Amendment to the third edition of ISO 6246 (2017)
Applications
The amendment to the ISO 6246 standard is practically significant for industries reliant on precise fuel quality monitoring, including:
- Fuel Testing Laboratories: Ensures standardized solvent quality for gum content testing, improving inter-laboratory reproducibility.
- Petroleum Refiners: Assists in quality control of refined products by accurately measuring gum content to prevent engine deposits and fuel degradation.
- Aviation Fuel Suppliers: Supports the evaluation of jet fuels, critical to maintain engine reliability and safety standards in aeronautics.
- Automotive Fuel Manufacturers: Helps in maintaining fuel specifications that affect vehicle engine efficiency and emissions.
- Regulatory Bodies: Provides a benchmark for fuel quality regulations ensuring compliance and consumer protection.
By enforcing a strict purity criterion for n-heptane, this amendment enhances the precision of gum content testing, directly impacting fuel formulation, stability, and performance assessments.
Related Standards
- ISO 8217: Specification for marine fuels - often used in conjunction with fuel testing methods such as ISO 6246.
- ISO 14212: Motor spirit - Determination of gum content - Hot evaporation method - Alternative to jet evaporation.
- ASTM D381: Standard test method for gum content in gasoline - similar techniques used with different solvents.
- ISO 4259: Petroleum products - Determination and application of precision data in measurement methods, relevant for lab testing accuracy.
These standards, together with ISO 6246 and its amendments, form a comprehensive framework for evaluating petroleum fuel quality worldwide. Compliance ensures consistent, reliable fuel analysis critical for industrial and commercial fuel applications.
Adhering to the updated ISO 6246:2017/Amd 1:2019 amendment guarantees that laboratories and industries use high-purity n-heptane, thereby supporting accurate gum content measurement and maintaining standards in fuel quality testing globally. This contributes not only to fuel integrity but also to environmental compliance and engine performance optimization.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
