Overview
ISO 5789:1979 specifies a standardized method for the determination of non-volatile residue in fluorinated hydrocarbons used in industrial applications. This international standard ensures the precise measurement of residue contents by employing evaporation of a test sample under controlled conditions, followed by the accurate weighing of the residue left behind. Developed by ISO Technical Committee ISO/TC 47 on Chemistry, this method provides a reliable basis for quality control and safety assessments in industries utilizing fluorinated hydrocarbons.
The standard is critical where eliminating non-volatile impurities is necessary, ensuring fluorinated hydrocarbons meet purity requirements essential for their functionality and regulatory compliance.
Key Topics
Scope
Defines the method for determining non-volatile residues in industrial fluorinated hydrocarbons, focusing on sample evaporation and residue quantification.Test Principle
The test portion is evaporated under specified conditions using specialized apparatus. The residue remaining after evaporation represents the non-volatile content.Apparatus Used
- Jacketed glass container with a ground glass stopper and a 500 ml graduation for sample containment
- Detachable glass element for holding the test portion during evaporation
- Electric oven controlled at 105 ± 2 °C for drying components
- Heating device such as a water bath or small electric oven to ensure uniform evaporation
Procedure Summary
The detachable element is dried and weighed, then connected to the glass container filled with the sample to a marked volume. Heating is applied uniformly until complete evaporation (1.5 to 2 hours), followed by drying and precise reweighing to determine residue mass.Result Expression
Non-volatile residue is expressed in milligrams per kilogram (mg/kg) of the sample using a defined calculation based on the mass difference before and after evaporation.Test Reporting
The standard mandates comprehensive reporting, including:- Sample identification
- Method reference
- Test results and units
- Observations during testing
- Any deviations or optional operations performed
Applications
ISO 5789:1979 is essential for companies and laboratories involved in the production, quality control, and safety assessment of fluorinated hydrocarbons used in diverse sectors such as:
- Refrigeration and air conditioning
- Fire suppression systems
- Electronics manufacturing (cleaning solvents)
- Chemical intermediates and raw materials
- Environmental monitoring of halogenated hydrocarbon purity
This standardized residue determination assists in verifying product purity, maintaining regulatory compliance, and ensuring chemical performance and safety in industrial processes.
Related Standards
- ISO 3427 – Gaseous halogenated hydrocarbons (liquefied gases) – Sampling method, which complements ISO 5789 by specifying sample collection procedures for testing fluorinated hydrocarbons.
- Other ISO standards covering chemical analysis, sampling methods, and purity assessment for industrial chemicals and solvents.
- Industry-specific guidelines on the handling and testing of halogenated solvents and refrigerants.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards institutes (ISO member bodies). The work of developing Interna-
tional Standards is carried out through ISO technical committees. Every member body
interested in a subject for which a technical committee has been set up 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.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council.
International Standard ISO 5789 was developed by Technical Committee ISO/TC 47,
C’hemistry, and was circulated to the member bodies in December 1977.
tt has been approved by the member bodies of the following countries :
Australia France Netherlands
