ASTM D891 - Apparent Specific Gravity of Liquid Industrial Chemicals
We perform quality testing by ASTM D891, which outlines two methods for determining the apparent specific gravity of liquid industrial chemicals. ASTM D891 determines the apparent specific gravity of liquid industrial chemicals using a hydrometer or a pycnometer. Apparent specific gravity can be used as a qualitative test to establish the identity of a chemical. It can also be used to calculate the volume of a product with a known weight, or to calculate the weight of a product with a known volume.
We also perform density and gravity testing by ASTM D1298, ASTM D1475, ASTM D287, ASTM D4052, DIN 51757, IP 160, and ISO 3675. These different test methods use different instruments or procedures or are used for certain sample types. Click on the test method number to learn more about each test.
