This International Standard 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 occur lie outside the scope of this International Standard. There are two kinds of failure: rapid shutdown by whole burst and softer crash of rotor. This International Standard applies to both. The same measurement method can be used for turbomolecular pumps and molecular drag pumps.
