ASTM D2166

ASTM D2166 is a standardized test method used to measure the amount of sediment (or how much solid material) in a slurry or liquid mixture, such as cement or mud. It involves pouring the mixture into a specially designed container, then allowing it to settle over time. The amount of sediment that settles at the bottom indicates the mixture’s clarity and consistency. This test helps ensure material quality and proper performance, especially in construction and drilling operations, by providing a clear, repeatable way to assess the amount of solid particles in a fluid.
