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 requirements”, 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".

Isopropyl Alcohol

Isopropyl Alcohol 99 dissolves a wide range of non-polar compounds. It evaporates quickly and the typically available grades tend to not leave behind oil traces Solvent Raw Material when used as a cleaning fluid unlike some other common solvents. It is also relatively non-toxic. Thus, it is used widely as a solvent and as a cleaning fluid, especially for situations where there can be oils or other oil based residues which would not be easily cleaned with water, conveniently evaporating and Ipa Chemical (depending on water content, and other potential factors) posing less of a risk of corrosion or rusting than Ethylene-Vinyl Acetate plain water. Together Pvc Resin with ethanol, n-butanol, and methanol, it belongs to the group of alcohol solvents.

99% Isopropyl Alcohol is commonly used for cleaning eyeglasses, electrical contacts, audio or video tape heads, DVD and other optical disc lenses, removing thermal paste from heatsinks on CPUs and other IC packages.

Isopropyl alcohol vapor is denser than air and is flammable, with a flammability range of between 2 and 12.7% in air. Ipa Isopropyl Alcohol should be kept away from heat and open flame.Distillation of isopropyl alcohol over magnesium has been reported to form peroxides, which may explode upon concentration.
