This document specifies methods and special requirements for measuring the maximum tolerable pressure difference, effective compression ratio, compression ratio with zero throughput and overflow valve pressure difference of mechanical booster vacuum pumps. It applies to mechanical booster vacuum pumps employed for medium vacuum or rough vacuum applications including gas cooled mechanical booster vacuum pump and multiple
