Overview

EN ISO 4625-1:2020 - Binders for paints and varnishes: Determination of softening point - Part 1: Ring-and-ball method is the CEN-endorsed European adoption of ISO 4625-1:2020. It specifies laboratory test methods (both automated and manual ring-and-ball procedures) for determining the softening point of resins and rosin-based binders used in paints and varnishes. The automated ring-and-ball method is declared the reference method. This standard is widely used for quality control, material specification and regulatory reporting in the coatings and adhesive industries.

Key Topics and Requirements

Scope and materials: Applies to resins (including rosin) and similar thermoplastic binder materials used in coatings.

Test methods: Defines both the automated ring-and-ball method (reference) and a manual ring-and-ball method (alternate).

Sampling and preparation: Requirements for sampling and procedures to prepare test pieces, including a pour method and special handling for low softening point materials.

Apparatus and calibration: Detailed apparatus descriptions and calibration requirements (including temperature sensors) to ensure repeatable results.

Procedures by temperature range: Specified procedures for materials with softening points in different ranges (e.g., up to ~35 °C, between ~35 °C and 80 °C, 80 °C–150 °C, and above 150 °C).

Test reporting and interpretation: Guidance on expression of results, recording of test conditions, and reporting precision, bias and uncertainty.

Precision and bias: Precision data and inter-laboratory considerations for both automated and manual methods are included.

Normative references: Cross-references to ISO 4618 (terms and definitions), ISO 15528 (sampling) and IEC 60751 (temperature sensors).

Applications and Who Uses It

Quality control laboratories in paint, varnish and resin manufacturing to verify softening behavior of binders.

R&D teams developing coating formulations where thermoplastic transitions affect performance.

Regulatory and compliance professionals, since ISO 4625-1 is referenced in regulatory contexts (e.g., Title 21 CFR).

Procurement and specification writers who need standardized softening point data for material selection and supplier contracts.

Test houses and certification bodies performing accredited testing of coating raw materials.
