Description

This Ministerial decree mandates that the producers and importers must abide by ES 4603-2. _x000D_
A transitional period of six months is given to abide by the standard. _x000D_
This Standard applies to land-based steam turbines and generators with power outputs greater than 50 MW and a normal operating speed of 1 500 r/min, 1 800 r/min, 3 000 r/min or 3 600 r/min. It is also applicable to steam turbines and/or generators which are directly coupled to a gas turbine (such as for combined-cycle applications). In such cases, the criteria of this part of the standard apply only to the steam turbine and the generator (including synchronizing clutches). ISO 7919-4 and ISO 10816-4 are applicable to the evaluation of the gas turbine vibration._x000D_
The numerical values specified are not intended to serve as the only basis for judging the severity of vibration._x000D_
For large steam turbines and generators, it is also common to judge the vibration based on measurements taken on non-rotating parts. For such vibration measurement requirements, see ISO 10816-1 and ISO 10816-2._x000D_
Worth mentioning is that this standard complies with ISO 10816-2/2009.
