Overview

ISO 4625-1:2020 - Binders for paints and varnishes - Determination of softening point - Part 1: Ring-and-ball method - specifies standardized test methods for measuring the softening point of resins (including rosin) and similar binder materials using the ring-and-ball apparatus. The document defines both an automated (reference) method and a manual (alternate) method, sampling and specimen preparation procedures, bath media, calibration, test procedures across temperature ranges, and reporting requirements.

Key topics and technical requirements

Definition and principle: Softening point is the temperature at which a sample disc in a horizontal ring is forced downward 25 mm by a steel ball under a prescribed heating rate.

Sampling & specimen preparation: Guidance on representative sampling (per ISO 15528), pour method for melts, and a special procedure for low softening-point materials (≤ 35 °C) including cooling on dry ice or in a freezer.

Methods specified:

Automated ring-and-ball method - designated as the reference method; includes apparatus, calibration and procedures for different softening-point ranges.
Manual ring-and-ball method - alternate method with its own apparatus, calibration and stepwise procedures.

Heating-bath liquids: Recommended fluids by softening-point range:

Distilled/deionized water for 35 °C–80 °C (use freshly boiled water)
Glycerol (CAS 56-81-5) for 80 °C–150 °C (USP grade)
Silicone oil (polymethylsiloxane) for >80 °C (stable to ≥200 °C)

Calibration, precision & bias: Procedures for calibrating equipment and published precision data for both automated and manual methods to ensure reproducibility.

Result expression and test report: Instructions for documenting the method used, conditions, and measured softening point.

Applications and users

Laboratory technicians and quality control teams in the paints, coatings and varnishes industry

R&D departments testing rosin-based resins and binders

Manufacturers specifying softening behavior for formulation and processing

Regulatory bodies and compliance testing (notably referenced in Title 21 CFR in regulatory contexts) This standard supports product specification, batch acceptance, process control, and comparative testing between materials.
