Overview

ISO 3671:2023 specifies a standardized laboratory method for the determination of volatile matter (predominantly water) in aminoplastic moulding materials by oven drying. The procedure provides a repeatable way to quantify moisture/volatile loss from thermosetting aminoplastic compounds to support quality control, product specification and material characterization.

Key topics and technical requirements

  • Scope: Determination of volatile matter in aminoplastic moulding materials by drying in an oven.
  • Sample storage: Store samples in an airtight container prior to testing to prevent loss or gain of moisture or other volatiles.
  • Apparatus:
    • Two wide‑mouthed weighing bottles (internal diameter 45 mm, depth 35 mm) with tight‑fitting covers.
    • Well‑ventilated oven controlled at (55 ± 1) °C.
    • Analytical balance with an accuracy of 0.001 g.
  • Procedure (summary):
    • Record the mass of a clean, dried empty weighing bottle to 0.001 g.
    • Weigh (5 ± 0.1) g of sample into the bottle (spread evenly); perform the test in duplicate.
    • Place uncovered bottles in the oven at 55 ± 1 °C for 3 hours. Then close bottles, transfer to a desiccator for at least 1 hour, equalize pressure and reweigh.
  • Calculation: The volatile matter percentage is calculated from the mass loss during drying relative to the initial sample mass. The arithmetic mean of the two determinations is reported.
  • Reporting: Test reports must reference ISO 3671:2023 and include product identification, individual and mean results, any deviations or unusual observations, and the test date.

Applications and users

ISO 3671:2023 is designed for practical use in:

  • Quality control laboratories at manufacturers of aminoplastic moulding compounds and molded parts.
  • Incoming inspection for raw material suppliers and processors to verify moisture/volatile specifications.
  • R&D and material development teams assessing formulation stability or drying treatments.
  • Regulatory and compliance testing where standardized moisture determination is required. Using this method helps ensure consistent product performance (e.g., dimensional stability, cure behavior) and reduces variability due to uncontrolled moisture content.

Related information

  • Prepared by ISO/TC 61 (Plastics), Subcommittee SC 12 (Thermosetting materials).
