Application Summary AI generated

This standard specifies a method for determining the skeletal density of solid materials by measuring the volume of a sample using gas pycnometry, based on the principle of gas displacement. It is primarily applied in materials science and quality control for testing porous or powdered materials, such as catalysts, ceramics, and pharmaceuticals, where accurate density measurement is critical for evaluating porosity and material composition. The method is used in laboratory settings to ensure consistency and reliability in research, production, and product certification.
