Why this test matters
Density and porosity strongly influence mechanical strength, durability, and performance. Deviations can indicate internal voids, incomplete consolidation, or process instability. The Archimedes measurement helps companies detect these issues early and avoid failures in use or rejection during qualification. It is a widely accepted method for quality control, material validation, and compliance. Typical users include manufacturers of metals, ceramics, polymers, composites, and additively manufactured parts.
How the test works
The test is based on buoyancy, which reflects how objects behave when immersed in a fluid. A dry sample is first weighed in air. It is then immersed in a liquid, usually water, and weighed again. From the difference between the two measurements, the sample volume is calculated. Combined with mass, the bulk density is determined. When required, additional steps such as vacuum impregnation allow open porosity to be measured. Tests are performed at controlled temperature to ensure accuracy.
What you learn from this test
The results provide bulk density and, when applicable, open porosity values. These data help assess material quality, compare production batches, and evaluate the impact of processing parameters. Engineers use the results to optimize designs, select materials, and validate manufacturing routes. The insights support confident decisions related to performance, durability, and conformity with standards or customer requirements.
