    Abstract - (Show below) - (Hide below)

    Deals with methods and procedures that apply to newly manufactured direct connected induction type watthour meters of Class 2. Proposes with two methods of acceptance inspection: sampling inspection and 100% inspection. Describes two methods of sampling inspection: inspection by variables and inspection by attributes.
