What is ISO 21360-3- Methods for measuring vacuum pump performance about? ISO 21360 is a series on Vacuum technology. Vacuum technology is a method used to evacuate air from a closed volume by creating a pressure differential from the closed volume to some vent, the ultimate vent being the open atmosphere. ISO 21360-3 specifies methods and special requirements for measuring the maximum tolerable pressure difference, effective compression ratio, compression ratio with zero throughputs and overflow valve pressure difference of mechanical booster vacuum pumps. ISO 21360-3 applies to mechanical booster vacuum pumps employed for medium vacuum or rough vacuum applications including gas-cooled mechanical booster vacuum pumps and multiple mechanical booster vacuum pump systems. ISO 21360-3 covers characteristics of mechanical boosters that are different from those of the usual positive displacement vacuum pumps. Maximum tolerable pressure difference Δ p max , effective compression ratio K eff , compression ratio with zero throughput K 0 and overflow valve pressure difference Δ p
