Gravity Test Plastic Sheet

1 1 these test methods describe the determination of the specific gravity relative density and density of solid plastics in forms such as sheets rods tubes or molded items.

Gravity test plastic sheet.

Densimeter specific gravity tester is an advanced density testing equipment for measuring solid and liquid samples with high precision sensor and auto weighing function. The astm test method describes the determination of specific gravity and density of solid plastics of different forms such as sheets rods tubes or other molded items. It is then immersed in a liquid and its apparent mass upon immersion is measured. 1 2 1 test method a for testing solid plastics in water and.

To test the specific gravity of liquids first pour a sample of liquid into a container. Next make sure the liquid is the same temperature that the hydrometer is calibrated to or you will get an incorrect reading.

There are chiefly two test methods are involved. You ll need to use a container that is deep enough to allow a hydrometer to float. 1 2 two test methods are described. One of the astm test methods for plastic commonly seen on data sheets is the test for density and specific gravity sg.

Density refers to the mass per unit volume of a material whereas sg refers to a measure of the ratio of mass of a given volume of material at 23 c to the same volume of deionized water.
