标准摘要
[中文适用范围]： 本国际标准规定了由轴流式叶片和/或螺旋通道产生气体动量的涡轮分子泵快速关闭扭矩（破坏性扭矩）的测量方法。 导致涡轮分子泵失效的主要力是绕旋转轴的扭矩。 其他可能发生的微不足道的力和力矩不属于本国际标准的范围。 故障有两种：整体爆裂快速停机和转子较软的碰撞。 本国际标准适用于两者。 相同的测量方法可用于涡轮分子泵和分子拖曳泵。 [外文原描述]： ISO 27892:2010 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 ISO 27892:2010. There are two kinds of failure: rapid shutdown by whole burst and softer crash of rotor. ISO 27892:2010 applies to both. The same measurement method can be used for turbomolecular pumps and molecular drag pumps.
