The tests for density and SG are particularly significant in the custom sheet industry because plastic sheet is sold on a cost per pound basis. One of the most basic differences between varieties, however, can be found in how much they weigh. Specific gravity of a material can be calculated by following equation: The testing method of SG for plastic systems is ASTM D792 and ISO 1183. SG of plastic is less compared to other materials influence its price; thus all plastic materials are sold on cost per weight basis. Density vs Specific Gravity - Tekra Should reactivate cookies?
