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. Two test methods are described: Test Method A—For testing solid plastics in water, and Test Method B—For testing solid plastics in liquids other than water. The values stated in SI units are to be regarded as the standard. Warning—Mercury has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Use caution when handling mercury and mercury-containing products.
