Svellingstester
Svellingstester is a term used for instruments and setups designed to measure how much a material swells when it absorbs moisture, solvents, or is exposed to heat. The tests are used to assess dimensional stability and how materials behave in hygroscopic or solvating environments.
The basic principle involves conditioning a specimen with defined dimensions in a controlled environment where humidity,
Configurations vary by material and purpose. In polymers and composites, swelling tests often use immersion or
Results from svellingstester inform material selection, product design, and quality control by indicating how much a
