Vacuum technology. Turbomolecular pumps. Measurement of rapid shutdown torqueBS ISO 27892: 2010 Vacuum technology. Turbomolecular pumps. Measurement of rapid shutdown torque BS ISO 27892 specifies a method for the measurement of rapid shutdown torque (destructive torque) of turbomolecular pumps in which gas momentum is produced by axial flow type blades and or helical channels. The main forces leading to failure of turbomolecular pumps are torques around the rotational axis. Other insignificant forces and moments that can
