This document provides guidelines for evaluating the vibration measurements made at the bearings, bearing pedestals or bearing housings and also for evaluating relative shaft vibration measurements made on machine sets in hydraulic power generating and pump-storage plants when the machine is operating within its normal operating range. The normal operating ranges for each type of turbine covered by this document are defined in Annex A. This document is applicable to machine sets in hydraulic power generating plants and in pump-storage plants with typical rotational speeds of 60 r/min to 1 000 r/min fitted with shell or pad (shoe) type oil-lubricated bearings. NOTE The current database includes machine speeds ranging from 60 r/min to 750 r/min (with a very small sample of 1 000 r/min machines). This document defines different limit values of bearing housing and shaft vibration depending on the type of turbine, the orientation of the shaft (i.e. horizontal or vertical) and for each of the bearing locations. This document is based on statistical analysis and provides criteria for the most common types of turbines, pump-turbines and pumps. For specific information on which types of units are covered in this document, see Annex A. Machine sets covered by this document can have the following configurations: a) generators driven by hydraulic turbines; b) motor-generators driven by pump-turbines; c) motor-generators driven by hydraulic turbines and separate pumps; d) pumps driven by electric motors. This document is not applicable to the following unit configurations, parameters and operating conditions: — hydraulic machines with water-lubricated bearings; — hydraulic machines or machine sets having rolling element bearings (for these machines, see IEC 62006 and/or ISO 10816‑3); — pumps in thermal power plants or industrial installations (for these machines, see ISO 10816‑7); — electrical machines operating as motors except for the use of these machines in pump-storage applications; — hydro generators operating as synchronous condensers (with the water in the turbine depressed by compressed air); — assessment of absolute bearing housing vibration displacement; — assessment of axial vibration; — assessment of transient conditions; — non-synchronous operation; — assessment of vibration of the generator stator core or the stator frame level. Measurements made of the bearing housing vibration and shaft vibration occurring in machine sets in hydraulic power generating and pump-storage plants can be used for the following purposes: 1) Purpose A: to prevent damage arising from excessive vibration magnitudes; 2) Purpose B: to monitor changes in vibrational behaviour in order to allow diagnosis and/or prognosis. The criteria are applicable for the vibration produced by the machine set itself. Special investigation is needed for vibration transmitted to the machine set from external sources, e.g. transmitted to the machine via the station foundations.

ISO 20816-2:2017 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 ISO 20816-2:2017 can be applied to the vibration of the gas turbine, steam turbine and generator (including synchronizing clutches). ISO 20816-2:2017 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. These are in terms of the following: - vibration under normal steady-state operating conditions; - vibration during other (non-steady-state) conditions when transient changes are taking place, including run up or run down, initial loading and load changes; - changes in vibration which can occur during normal steady-state operation. ISO 20816-2:2017 is not applicable to the following: i) electromagnetic excited vibration with twice line frequency at the generator stator windings, core and housing; ii) aero-derivative gas turbines (including gas turbines with dynamic properties similar to those of aero-derivatives); NOTE ISO 3977‑3 defines aero-derivatives as aircraft propulsion gas generators adapted to drive mechanical, electrical or marine propulsion equipment. Large differences exist between heavy-duty and aero-derivative gas turbines, for example, in casing flexibility, bearing design, rotor-to-stator mass ratio and mounting structure. Different criteria, therefore, apply for these two turbine types. iii) steam turbines and/or generators with outputs less than or equal to 40 MW or with rated speeds other than 1 500 r/min, 1 800 r/min, 3 000 r/min or 3 600 r/min (although generators seldom fall into this latter category) (see ISO 7919‑3 and ISO 10816‑3); iv) gas turbines with outputs less than or equal to 40 MW or with rated speeds other than 1 500 r/min, 1 800 r/min, 3 000 r/min or 3 600 r/min (see ISO 7919‑3 or ISO 7919‑4 and ISO 10816‑3 or ISO 10816‑4); v) the evaluation of combustion vibration but does not preclude monitoring of combustion vibration.

This part of ISO 8528 defines design requirements, minimum performances and type tests for lowpower
generating sets driven by reciprocating internal combustion engines for land and marine use
(domestic, recreational and industrial application), excluding generating sets used on aircraft.
It concerns mainly low-power generating sets driven by reciprocating internal combustion engines for
the generation of single or multiphase alternating current or direct current up to 500 V. The generating
sets are standard manufactured sets.
In this part of ISO 8528, “low-power” is taken to mean rated power of a magnitude up to approximately
10 kW/50 Hz, 12 kW/60 Hz. Low-power generating sets, for the purpose of this International Standard,
are determined by the following special features:
— the users normally are laymen (for further details, see 3.1);
— the complete generating set is usually transportable or mobile;
— the electrical output is connected by means of plugs, sockets and screwed terminal except for extra
low voltages;
— the generating set is ready for use without any additional installation work by the user.
Generating sets for special applications or of higher rated power conforming to the above special
features may, by agreement between manufacturer and customer, be tested in accordance with this
part of ISO 8528. If supplementary stipulations are required for certain applications, this is to be done
taking this part of ISO 8528 as a basis.
This part of ISO 8528 deals with the special requirements of design and test which are observed
in addition to the definitions and requirements laid down in ISO 8528-1, ISO 8528-2, ISO 8528-3,
ISO 8528-4, ISO 8528-5 and ISO 8528-6, where applicable.
This part of ISO 8528 does not deal with safety requirements in order to protect the user from dangers
which are laid down in ISO 8528-13.

ISO 22266-1:2009 provides guidelines for applying shaft torsional vibration criteria, under normal operating conditions, for the coupled shaft system and long blades of a turbine generator set. In particular, these apply to the torsional natural frequencies of the coupled shaft system at line and twice‑line frequencies of the electrical network to which the turbine generator set is connected. In the event that torsional natural frequencies do not conform with defined frequency margins, other possible actions available to vendors are defined. ISO 22266-1:2009 is applicable to land-based steam turbine generator sets for power stations with power outputs greater than 50 MW and normal operating speeds of 1 500 r/min, 1 800 r/min, 3 000 r/min and 3 600 r/min, and to land-based gas turbine generator sets for power stations with power outputs greater than 50 MW and normal operating speeds of 3 000 r/min and 3 600 r/min. Methods currently available for carrying out both analytical assessments and test validation of the shaft system torsional natural frequencies are also described.

ISO 8528-4:2005 specifies the criteria for controlgear and switchgear for generating sets with reciprocating internal combustion engines. It applies to Alternating Current (a.c.) generating sets driven by Reciprocating Internal Combustion (RIC) engines for land and marine use excluding generating sets used on aircraft or to propel land vehicles and locomotives. For some specific applications (e.g. essential hospital supplies and high-rise buildings), supplementary requirements may be necessary. The provisions of ISO 8528-4:2005 should be regarded as a basis for establishing any supplementary requirements. For generating sets driven by other prime movers (e.g. steam engines) ISO 8528-4:2005 should be regarded as a basis for establishing these requirements.

This  International  Standard,  which  forms  part  of  the  ISO  8528  series,  specifies  criteria,  
including  performance  and  test  methods,  for  rotary  uninterruptible  power  systems  (UPS)  
arising  out  of  a  combination  of  mechanical  and  electrical  rotating  machines.  This  standard  
applies  to  power  supplies  primarily  designed  for  supplying  uninterrupted  a.c.  power  to  the  
consumer.  When  operated  without  input  mains  feed,  the  power  is  provided  by  stored  energy  
and/or  reciprocating  internal  combustion  (RIC)  engine  and  the  output  power  is  provided  by  
one or more rotating electrical machines.
This  part  11  applies  to  a.c.  power  supplies  primarily  designed  for  supplying  uninterruptible  
electrical  power  for  stationary  land  and  marine  use,  excluding  supplies  for  aircraft,  land  
vehicles or locomotives. It also excludes power supplies where the output power is generated
by static converters. (See IEC 62040-3.)
The  use  of  a  rotary  UPS  installation  to  improve  the  quality  of  a.c.  power  supply,  to  provide  
voltage and/or frequency conversion, and to provide peak shaving is also described.
For  some  specific  applications  (for  example,  essential  hospital  supplies,  offshore,  non-
stationary applications, high rise buildings, nuclear, etc.) supplementary requirements may be
necessary. The provisions of this part of ISO 8528 should be used as a basis.

This part of ISO 8528 defines measurement methods for the determination of airborne noise emitted by
reciprocating internal combustion engine driven generating sets in such a way that the total of relevant noise
emissions, e.g. exhaust and cooling system noise, together with all other sources of engine noise, are evaluated on
a similar basis to yield comparable results. However, when the exhaust and cooling systems are ducted to a remote
site their noise contribution is not to be included in this part of ISO 8528.
The essential noise emission characteristic value is the sound power level.
The results of measurement taken in accordance with this part of ISO 8528 are classified as either accuracy grade
2 or grade 3 depending on which acoustic measurement conditions are complied with. Accuracy grade 2 (i. e.,
engineering method in accordance with ISO 3744) requires the measuring area to be a substantially acoustic-free
field over a reflecting plane (with an environmental correction K2A < 2 dB) and with negligible background noise
level (background noise correction K1A < 1,3 dB). Accuracy grade 3 (i. e. survey method in accordance with
ISO 3746) requires the environmental correction K2A to be less or equal than 7 dB, and the background noise
correction K1A to be less or equal than 3 dB.
For the operation of a generating set under steady conditions this part of ISO 8528 allows for the calculation of the
A-weighted sound power level as well as appropriate octave or one third octave sound power level for the
appropriate accuracy grade.
This part of ISO 8528 applies to RIC engine driven AC generating sets for fixed and mobile applications with rigid or
flexible mountings. It is applicable for land and marine use, excluding generating sets used on aircraft or to propel
land vehicles and locomotives.
NOTE 1 This part of ISO 8528 has been developed for RIC engine driven AC generating sets, but it can also be applied to RIC
engine driven DC generating sets.
NOTE 2 For some specific applications (e. g. essential hospital supplies, high rise buildings, etc.) supplementary requirements
may be necessary. The provisions of this part of ISO 8528 should be regarded as a basis.
NOTE 3 True comparisons can only be made between generating sets when the measurement are classified in the same
accuracy grade.

This part of ISO 8528 defines requirements, minimum performances and type tests for low-power generating sets driven by reciprocating internal combustion
engines for land and marine use (domestic, recreational and industrial application), excluding generating sets used on aircraft.
lt concerns mainly Iow-power generating sets driven by reciprocating internal combustion engines for the generation of Single or multiphase alternating current
or direct current up to 500 V. The generating sets are Standard manufactured sets that tan be selected from a commercial catalogue or leaflet.
In this part of ISO 8528, “low power” is taken to mean power of a magnitude up to approximately 10 kW.
NOTE 1 An exact determination of a power Iimit is not possible.
Low-power generating sets for the purpose of this Standard are determined by the following special features:
- the users normally are laymen (for further details see 3.1);
- the complete generating set is usually transportable, or mobile;
- the electrical output is connected by plugs and sockets (except for extra low voltages; see 6.6.3);the generating set is ready for use without any
additional installation work by the User.
Generating sets for special applications or of higher rated power conforming to the above special features may, by agreement between manufacturer and customer, be tested in accordance with this part of ISO 8528. If supplementary stipulations are required for certain applications this should be done taking this
patt of ISO 8528 as a basis. This part of ISO 8528 deals with the special requirements of test and safety design which should be observed in addition to the definitions and requirements laid down in ISO 8528 Parts 1 to 6, where applicable. Furthermore it lays down safety requirements in Order to protect the user from danger.
