This standard specifies metrological requirements, among others, for oscillation-type density meters as well as for functional units (see 4.2) of oscillation-type density meters, which are used in process for all kinds of homogenous liquids. This includes liquified gases. This standard does not describe the method of use of process density meters for particular applications or products, e.g petroleum products or beverages.
