本国家采用的国际标准适用于输出功率大于40 MW的陆上燃气轮机、蒸汽轮机和发电机（无论是否与燃气轮机和/或蒸汽轮机耦合），液膜轴承，额定转速为1500 r/min、1800 r/min、3000 r/min或3600 r/min。本文件中提供的标准可适用于燃气轮机的振动，汽轮机和发电机（包括同步离合器）。本文件规定了评估以下情况严重性的规定:- 现场宽带振动:a）所有主轴箱或底座上的结构振动，径向（即横向）测量轴轴线；b） 轴向测量推力轴承箱的结构振动；c） 在主轴承处或靠近主轴承的轴径向（即横向）旋转轴的振动。

This nationally adopted international standard is applicable to land-based gas turbines, steam turbines and generators (whether coupled with gas and/or steam turbines) with power outputs greater than 40 MW, fluid-film bearings and rated speeds of 1 500 r/min, 1 800 r/min, 3 000 r/min or 3 600 r/min. The criteria provided in this document can be applied to the vibration of the gas turbine, steam turbine and generator (including synchronizing clutches). This document establishes provisions for evaluating the severity of the following in-situ, broad-band vibration:a) structural vibration at all main bearing housings or pedestals measured radial (i.e. transverse) to the shaft axis;b) structural vibration at thrust bearing housings measured in the axial direction;c) vibration of rotating shafts radial (i.e. transverse) to the shaft axis at, or close to, the main bearings.
