Mechanical vibration - Evaluation of machine vibration by measurements on non-rotating parts - Part 4: Gas turbine sets with fluid-film bearing
ISO 10816-4는 3MW 이상의 출력과 Fluid Film Bearing이 적용되고 운전 속도가 3,000~30,000rpm에 해당하는 Gas Turbine의 site에서 측정한 진동 기준치에 적용하며, Bearing Housing의 진동을 RMS 단위로 평가하는데 이용한다.
1. 진동 평가(Steady State Condition)

○ Zone A : Newly commissioned machine
○ Zone B : This zone is considered as acceptable level for unrestricted long-term operation
○ Zone C : Normally considered unsatisfactory for long-term operation
○ Zone D : Normally considered to be sufficient severity to cause mechanical damage
2. 진동 평가(Transient Condition)
Transient Condition at Rated Speed에서의 진동은 Zone Boundary C/D이내로 적용되어야 한다. 또한, Transient Condition at Run Up/Down or Over-Speed에서의 진동은 Zone Boundary C/D이내로 적용되어야 한다.
3. 진동 측정 위치
