通告描述：

This Ministerial Decree mandates that the producers and importers must abide by ES 4603-4. A transitional period of six months is given to abide by the Standard. This Standard establishes provisions for evaluating the severity of in-situ, broad-band vibration measured radial (i.e. transverse) to the shaft axis on all main bearing housings or pedestals and in the axial direction on thrust bearings. These are in terms of:<ul><li>vibration under normal steady-state operating conditions;</li><li>vibration during other (non-steady-state) conditions when transient changes are taking place, including run up or run down, initial loading and load changes;</li><li>changes in vibration which can occur during normal steady-state operation.</li></ul>This part of this Standard is applicable to heavy-duty gas turbine sets used in electrical and mechanical drive applications, with fluid-film bearings, outputs greater than 3 MW and an operating speed range under load between 3 000 r/min and 30 000 r/min. This includes gas turbines coupled to other rotating machinery either directly or through a gearbox. In some cases, this part of this standard is not applicable to the evaluation of the vibration of the coupled equipment (see the list of exclusions in this clause). Worth mentioning is that this standard complies with ISO:10816-4:2009.
