ISO 4324:1977 – Measurement of the Angle of Repose: Evaluating Material Flow Properties in Bulk Solids Handling

/ / Published in ISO Test Standards, Science and Research

ISO 4324:1977 is a standard that measures how powders and granular materials pile up when poured. When you work with bulk materials like sand, flour, or pharmaceutical powders, knowing the angle of repose helps predict how these materials will behave during storage, transportation, and processing. This measurement is crucial for engineers designing hoppers, silos, and…
