A few days ago, the National Pump Standardization Technical Committee National Standard Drafting Working Group meeting was held in Kunming. Two comrades, Sun Bing and Lu Binbin, from the valve and valve center of Jiangsu Province attended the meeting.
During the meeting, representatives of experts discussed the comments on the “precision grades of hydraulic performance test specifications for centrifugal pumps, mixed-flow pumps and axial-flow pumps†and “hydrostatic pressure test for liquid pump safety requirementsâ€, and filled out a summary table for soliciting opinions. And prepare the review draft.
The “precision class of hydraulic performance test specifications for centrifugal pumps, mixed flow pumps and axial flow pumps†is based on the second batch of national standards revision plan in 2013 (GBS General [2013] No. 90), plan number 20131904-T-604, project The name "precision grades for hydraulic performance test of centrifugal pumps, mixed-flow pumps and axial-flow pumps" was revised to replace GB/T18149-2000.
The “Liquid Pump Safety Requirements for Hydrostatic Pressure Test†is based on the “National Standards Committee General [2013] No. 90†issued in 2013 for the second batch of national standards revision plan, and the project number 20131905-T-604 plan number, the project name “Liquid The requirements for the hydrostatic pressure test method for pump safety requirements were formulated. This standard adopts EN12162:2001 A1:2009 "Liquid pump safety requirements for hydrostatic pressure test procedures".
