Notice on Issuing Six Industry Standards Including "Glass Plate Liquid Level Meter"
To the Chemical Industry Departments (Bureaus, Companies) of all provinces, autonomous regions, municipalities directly under the Central Government and cities with independent planning status, and all relevant design units: The six standards including "Glass Plate Liquid Level Meter" organized by the Equipment Design Technology Center of the Ministry of Chemical Industry and edited by China Huanqiu Chemical Engineering Company have been approved as mandatory industry standards after review (see the attached table for the standard names and numbers), and will be implemented from March 1, 1997. At the same time, the original chemical standards HG51363~1370-80 and HG5-227-80 were abolished.
These six standards are managed by the Equipment Design Technology Center of the Ministry of Chemical Industry, and published and issued by the Ministry's Engineering Construction Standards Editing Center.
