Overview
SIST EN ISO 3671:2023 is the updated international standard specifying the procedure for determining volatile matter in aminoplastic moulding materials, primarily focusing on moisture content. Developed by ISO/TC 61 and endorsed by CEN in 2023, this standard replaces the previous 1998 edition to reflect the latest industry practices. It details a reliable oven-drying method to quantify the amount of volatile substances, such as water, present in aminoplastic plastics used for moulding applications.
The standard aims to provide manufacturers, quality control laboratories, and research institutions with a consistent, precise test method to evaluate volatile matter content-an essential factor impacting the performance and stability of aminoplastic moulding materials.
Key Topics
Scope: Measurement of volatile matter predominantly water in aminoplastic moulding materials using drying in a controlled-temperature oven.
Apparatus Requirements:
- Wide-mouthed weighing bottles with tight covers, 45 mm diameter and 35 mm depth.
- Well-ventilated oven controllable at 55 ± 1°C.
- Precision balance with an accuracy of 0.001 g.
Sample Handling and Storage: Test specimens must be stored in airtight containers before testing to prevent moisture loss or gain, ensuring accurate results.
Test Procedure:
- Weigh an empty dried bottle.
- Add approximately 5 grams of sample, spread evenly.
- Place uncovered bottles in an oven at 55 °C for 3 hours.
- Seal bottles and cool in a desiccator for at least 1 hour.
- Equalize bottle pressure and reweigh.
- Perform duplicate tests to validate measurement consistency.
Calculation:
Volatile matter percentage is calculated from the weight difference before and after drying, averaged over two tests.Reporting: Essential elements include reference to SIST EN ISO 3671:2023, product identification, results of both determinations, any deviations, observations, and date of testing.
Applications
SIST EN ISO 3671:2023 is vital in applications where aminoplastic moulding materials are employed, such as:
Quality Control: Ensures consistent product quality by monitoring moisture and volatile content that can affect curing, mechanical properties, and dimensional stability.
Material Certification: Supports manufacturers and suppliers in certifying aminoplastic materials meet specified standards for volatile matter content.
Research and Development: Assists in developing new aminoplastic formulations by providing accurate volatility data critical for performance optimization.
Industry Sectors: Utilized in the production of electrical components, household items, and automotive parts where thermosetting aminoplastic resins are common.
By adopting this standardized method, industries can enhance product reliability, comply with regulatory requirements, and minimize defects related to volatile substances.
