3、ethod,the property to be measured isclassified into three groups based on material type:1.1.1 Group AFree-flowing liquids;apparent specificgravity(ASG),1.1.2 Group BGranules,powders,and water-reactiveliquids,solids,or sludges;bulk density(BD),and1.1.3 Group CBulk solids(such as gravel,paper,or wood,
4、etc.);apparent specific gravity(ASG).1.2 This test method is designed and intended as a screeningtest to complement the more sophisticated quantitative analyti-cal techniques that may be used to determine specific gravity.This test method offers to the user the option and the ability toscreen waste
5、for apparent specific gravity or bulk density whenthe more sophisticated techniques are not available and thetotal waste composition is unknown.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard
