Full title and description

ISO 10363:1992 — Hot-melt adhesives — Determination of thermal stability. This International Standard specifies a laboratory method for assessing the thermal stability of hot‑melt adhesives by heating a sample in a stainless steel or glass vessel in an oil bath or oven, periodically measuring viscosity and softening point, and recording observable changes such as skin formation, fumes, phase separation, gelation and colour change.

Abstract

The method involves melting a sufficient quantity of adhesive in a suitable vessel placed in an oil bath or oven, measuring viscosity at the operating temperature and the softening point, and repeating these measurements at regular intervals (typically every 4 to 6 hours) until pre‑determined stopping criteria are reached. Observations recorded at each measurement include skin formation, fumes, phase separation, gelation and change in colour.

Scope

Specifies a laboratory test method to determine the thermal stability of hot‑melt adhesives under controlled elevated‑temperature conditions. The procedure covers sample containment (stainless steel or glass vessel), heating environment (oil bath or oven), the sequence of measurements (viscosity and softening point), the frequency of measurements (typical intervals of 4–6 hours), and the visual/physical phenomena to be observed and recorded during ageing (skin formation, fumes, phase separation, gelation, colour change). The standard is intended for comparative and quality assessment purposes rather than long‑term field ageing predictions.

Key topics and requirements

• Apparatus and sample containment: use of stainless steel or glass vessels and an oil bath or oven for controlled heating.
• Measurement parameters: periodic determination of viscosity at operating temperature and measurement of softening point.
• Test timing: repeat measurements at regular intervals (commonly every 4 to 6 hours) until stopping criteria are met.
• Observed phenomena to record: skin formation, fumes, phase separation, gelation and change in colour.
• Stopping criteria and record‑keeping: define criteria for terminating the test and maintain a log of measurements and observations for comparison and quality assessment.

Typical use and users

Used by hot‑melt adhesive manufacturers, product development and R&D laboratories, quality control and assurance teams, independent testing laboratories, and procurement/specification engineers to evaluate adhesive thermal stability, shelf/processing life at elevated temperatures, and formulation robustness.
