It is then immersed in a liquid and its apparent mass upon immersion is measured. 0 2 astm d792. 1 2 two test methods are described. Water absorption after 24 hr.

The more common being method a can be used with sheet rod tube and. There are chiefly two test methods are involved. 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. 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.

Test method a for testing solid plastics in water and. One of the astm test methods for plastic commonly seen on data sheets is the test for density and specific gravity sg. The mass of the specimen of the solid plastic in air is first measured.

About this quiz worksheet. Its multiplied by the gravitational field strength where the object weigh will be less at mars because there gravity is weaker more on saturn and. 1 2 1 test method a for testing solid plastics in water and. From falling apples to rising tides everything is affected by gravity.

Specific gravity and density are especially relevant because plastic is sold on a cost per pound basis and a lower density or specific gravity means more material per pound or varied part weight. Standard specification for nonrigid vinyl chloride plastic film and sheeting. In the other words an object with a mass of 1 0 kilogram with weigh approximately 9 81 newtons on the surface of the earth. This test is often seen with the designation astm d792.

One such test is the plastic sheet test astm d4263. Some methods of concrete moisture testing use a simple qualitative approach. This means no numbers or data just simple observation or eyeballing of the test location and testing materials for signs of excessive moisture. Whereas weight refers to the force exerted on an object by gravity.

Standard test method for resistance of plastic films to extraction by chemicals.
