Three national standards review conferences for basic parameters of hydraulic and pneumatic components - nominal pressure, nominal displacement, bore diameter and piston rod diameter series - were held in Kunshan County, Jiangsu Province from December 20 to December 1978. Participate in this National Standard Review Conference of the Institute of Higher Education, Research Institutes (Institutes) of the First, Third, Fifth, Sixth, Seventh, Ministry of Railways, Coal, Metallurgy, and Petrochemical, etc. Related factories and so on. The meeting was chaired by the National Standards Administration’s “National Joint Working Group on Standardization of Hydraulics and Pneumatic Components”.
