Overview
ISO 9455-1:2022 defines a gravimetric test method for determining the content of non-volatile matter in soft soldering fluxes. This standard applies specifically to liquid and paste fluxes of type 1, as classified under ISO 9454-1. Accurate measurement of non-volatile components in soldering fluxes is crucial for quality control and ensuring effective soldering processes in electronics and metal joining industries. The gravimetric approach involves evaporating volatile substances and weighing the remaining solid residue to calculate the proportion of non-volatile matter.
Key Topics
- Scope: Analytical determination of non-volatile matter in soft soldering fluxes using a standardized gravimetric technique.
- Applicability: Liquid and paste fluxes, type 1 category.
- Method Principle: A known mass of flux is heated first in a boiling water bath and then dried in an oven at 110 ± 2 °C to remove volatile components before weighing the residue.
- Apparatus Required:
- Glass Petri dish (100 mm diameter)
- Weighing pipette (20–25 ml capacity)
- Boiling water bath
- Drying oven (maintained at precise temperatures)
- Desiccator with silica gel
- Procedure Highlights:
- Sample preparation by weighing between 0.5 g and 1.0 g of non-volatile matter
- Triplicate testing for accuracy
- Evaporation of volatiles followed by oven drying and cooling in desiccator to prevent moisture absorption
- Weighing before and after drying to calculate non-volatile matter percentage
- Calculation Formula:
[ \text{Non-volatile matter %} = \frac{m_2}{m_1} \times 100 ] where ( m_1 ) is the initial sample mass and ( m_2 ) is the mass after drying. - Precision and Repeatability: Verified through interlaboratory testing; reproducibility and repeatability values are provided for samples with varying non-volatile contents (5%, 15%, 25%).
Applications
ISO 9455-1:2022 is vital for manufacturers, quality control laboratories, and end-users of soft soldering fluxes in various industries including:
- Electronics manufacturing: Ensuring solder flux quality aligns with industry standards to guarantee reliable solder joints.
- Metal fabrication and assembly: Controlling flux characteristics to optimize flow and adhesion during soldering.
- Materials testing labs: Performing standardized and reproducible measurements for certification and conformity assessment.
- Supplier and purchaser collaboration: Establishing a common method for evaluating flux consistency, especially when solvent types or activator contents differ.
By implementing this standard, organizations can maintain consistent flux quality, reducing soldering defects and improving product reliability.
Related Standards
- ISO 9454-1 - Soft soldering fluxes: Classification, labelling, and packaging of flux types, including type 1 fluxes referenced in ISO 9455-1.
- ISO 5725-1 - General principles and definitions of accuracy, trueness, and precision in measurement methods, used here to establish test precision.
- ISO/IEC Directives, Part 1 & 2 - Guidelines followed for the preparation and maintenance of this standard.
Understanding and applying the ISO 9455-1 methodology supports compliance with broader soldering process controls and enhances cross-border trade by aligning with internationally recognized flux testing protocols.

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
electrotechnical standardization.
