ABS 1.04-1.07 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. Electronics Instrumentation Machine Design Apps Specific Gravity Though some manufacturers use grams per cubic centimeter to indicate the weight of their products, others merely provide the specific gravity of their material. Ultimate tensile strength is the maximum stress the thermoplastic material can withstand before failing, whichever occurs at the higher stress level. Specific gravity, generally speaking, measures the density of an object as compared to water.
