Overview

SIST EN ISO 12224-2:2024 sets out standardized methods for determining the flux content in flux-cored solder wires. Published by CEN in alignment with ISO 12224-2:2024, this standard is crucial for manufacturers, testing laboratories, and quality assurance in industries that use solder wire, such as electronics, electrical engineering, and manufacturing. The document replaces the previous version (EN ISO 12224-2:1999), providing updated procedures and equipment requirements.

Flux in solder wire performs vital functions, such as removing oxides from metal surfaces, ensuring strong joints, and improving the quality and reliability of soldered connections. Accurate determination of flux content is essential for product consistency, compliance, and process optimization.

Key Topics

• Scope: Specifies two main standardized laboratory methods (as well as a third, optional method) for quantitatively measuring the flux content in flux-cored solder wires.
• General Principles: Explains that a known mass of flux-cored solder wire is melted, separated from the flux, and the mass difference is used to calculate the flux percentage.
• Apparatus and Materials: Lists required laboratory equipment, such as precision balances, crucibles (porcelain or quartz glass), tongs, solder baths, Bunsen burners, heat-resistant beakers, and degreasing solvents.
• Test Methods:
  • Method A (Solder Bath Method): Utilizes immersion of wire in a solder bath with procedures for flux separation and weighing.
  • Method B (Glycerol Method): Involves melting solder under glycerol, then decanting and cleaning before final weighing.
  • Method C: An alternative utilizing a Bunsen burner and rosin, specifically for low-flux-content wires.
• Result Calculation: Describes the simple mass-based equation for determining flux content and requirements for result validation and repeatability.
• Reporting: Outlines the essential test report contents, including sample identification, reference to the standard, method used, results, and any deviations.

Applications

SIST EN ISO 12224-2:2024 supports the solder wire industry and its customers by:

• Providing a uniform approach to flux content determination, ensuring comparability and traceability of results across different laboratories and settings.
• Enabling manufacturers to verify the composition of flux-cored solder wire, which is important for product development, quality control, and regulatory compliance.
• Supporting procurement and supply chain stakeholders in specifying and accepting solder wire products based on internationally accepted test results.
• Helping end-users in electronics assembly, automotive, and other sectors confirm that soldered joints meet performance and reliability requirements.
• Facilitating dispute resolution between suppliers and purchasers regarding flux content measurement, as the standard provides agreed test methods for reference.

Related Standards

SIST EN ISO 12224-2:2024 is part of a broader family of solder wire and soldering material standards:

• EN ISO 12224-1: Solder wire, solid and flux-cored - specifications and general test methods
• ISO 9453: Soft solder alloys - Chemical compositions and forms
• EN ISO 9454: Fluxes for soft soldering - Classification and requirements
• EN ISO 9455: Fluxes for soft soldering - Test methods

These standards collectively support consistent quality, safety, and interoperability in international soldering practices.
