Shaft vibration measurement requirements and criteria for gas turbine sets are addressed in separate 1081-64, ISO and ISO Discover Prime Book Box for Kids.

This includes gas turbines directly coupled to other prime movers such as steam turbines, but the evaluation of the steam turbine vibration is not dealt with in this part of Isp see the following exclusion list.
If application of the different criteria leads to different assessments of vibration severity, the more restrictive zone classification generally applies unless there is significant experience to the contrary. In such cases, it is normally necessary for the manufacturer to explain the reasons for this and, in particular, to confirm that the machine will not be endangered by operating with higher vibration values.
Using the procedure described in 4. For such cases and when peak rather than r. Machines with vibration within this zone are normally considered unsatisfactory for long-term continuous operation.

Change in vibration magnitude This criterion provides an assessment of a change in vibration magnitude from a previously established reference value. Such changes can be instantaneous or progressive oso time and may indicate incipient damage or some other irregularity. This standard is also available to be included in Standards Subscriptions. Your Alert Profile lists the documents that will be monitored. This will, in most cases, be adequate for acceptance testing and for operational monitoring purposes.
Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. If the vibration consists mainly of one frequency component, a simple relationship exists between the peak and r.
The vibration of izo commissioned machines would normally fall within this zone. The operational ALARM settings for a new machine for which there is no prior knowledge of bearing vibration is normally set within zone C. The zone boundary vibration values were established from representative data provided by manufacturers and users. Since the data showed significant spread, the zone boundary values should be considered only as guidelines.
Set up a giveaway. For gas turbine sets, it izo also common to judge the vibration based on measurements taken on the rotating shafts. Generally, the machine may be operated for a limited period in this condition until a suitable opportunity arises for remedial action. This includes gas turbines directly coupled to other prime movers such as steam turbines, but the evaluation of the steam turbine vibration is not dealt 100816-4 in this part of ISO see the following exclusion list.
