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.

1 2 two test methods are described. Astm d297 93 16 rubber astm d792 00 plastic jis k6268a jis k7112 plastic. 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.

You ll need to use a container that is deep enough to allow a hydrometer to float. 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. This test is often seen with the designation astm d792. The mass of the specimen of the solid plastic in air is first measured.

Test method a for testing solid plastics in water and test method b for testing solid plastics in liquids other than water. It is then immersed in a liquid and its apparent mass upon immersion is measured. Astm d792 98 describes the determination of the specific gravity relative density and density of solid plastics in forms such as sheets rods tubes or molded items. There are chiefly two test methods are involved.
