6、ional standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Interna
7、tional organizations, governmental and non- governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical comm
8、ittees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 10816-4 was prepared by Technical Committee ISO/TC 108 Mechanical vibration and shock, Subcommittee SC 2
9、Measurement and evaluation of mechanical vibration and shock as applied to machines, vehicles and structures. ISO 10816 consists of the following parts, under the general title Mechanical vibration Evaluation of machine vibration by measurements on non-rotating parts: Part 1: General guidelines Part
10、 2: Large land-based steam turbine generator sets in excess of 50 MW Part 3: Industrial machines with nominal power above 15 kW and nominal speeds between 120 r/min and 15 000 r/min when measured in situ Part 4: Gas turbine driven sets excluding aircraft derivatives Part 5: Machine sets in hydraulic
11、 power generating and pumping plants Part 6: Reciprocating machines with power ratings above 100 kW Annex A forms an integral part of this part of ISO 10816. Annexes B and C are for information only. -,-,- ISO 10816-4:1998(E) ISO iv Introduction ISO 10816-1 is the basic document which describes the
12、general requirements for evaluating the vibration of various machine types when the vibration measurements are made on non-rotating parts. This part of ISO 10816 provides specific guidance for assessing the severity of vibration measured on the bearing housings or pedestals of gas turbine driven set
13、s. Measurements at these locations characterize reasonably well the state of vibration. Two criteria are provided for assessing the machine vibration. One criterion considers the magnitude of the observed vibration; the second considers changes in the magnitude. It must be recognized, however, that
14、these criteria do not form the only basis for judging the severity of vibration. For gas turbine sets, it is also common to judge the vibration based on measurements taken on the rotating shafts. Shaft vibration measurement requirements and criteria for gas turbine sets are addressed in separate doc
15、uments, ISO 7919-1 and ISO 7919-4. -,-,- INTERNATIONAL STANDARD ISOISO 10816-4:1998(E) 1 Mechanical vibration Evaluation of machine vibration by measurements on non-rotating parts Part 4: Gas turbine driven sets excluding aircraft derivatives 1 Scope This part of ISO 10816 gives specific guidance fo
16、r assessing the severity of vibration measured on the bearing housings or pedestals of gas turbine driven sets. The vibration criteria provided in this part of ISO 10816 apply to heavy-duty gas turbine sets. Aircraft derivative gas turbines (including gas turbines with dynamic properties similar to
17、those of aircraft derivatives) are excluded from this part of ISO 10816. Large differences exist between these two turbine types in, for example, casing flexibility, bearing design, rotor to stator weight ratio and mounting structure. It is therefore necessary to establish separate criteria for thes
18、e two turbine types. This part of ISO 10816 is applicable only to heavy-duty gas turbines used in electrical and mechanical drive applications covering the power range above 3 MW and a speed range under load between 3 000 r/min and 20 000 r/min. This includes gas turbines directly coupled to other p
19、rime movers such as steam turbines, but the evaluation of the steam turbine vibration is not dealt with in this part of ISO 10816 (see the following exclusion list). It also includes any driven equipment not included in the exclusion list below. The following are excluded from this part of ISO 10816
20、: gas turbines with power outputs less than or equal 3 MW (see ISO 10816-3); gas turbine driven pumps (see ISO 10816-3); coupled steam turbines and generators with outputs less than or equal 50 MW (see ISO 10816-3); coupled steam turbines and generators with outputs greater than 50 MW (see ISO 10816
21、-2); coupled compressors (see ISO 10816-3); gearbox vibration (see below). The criteria of this part of ISO 10816 are applicable to the vibration measured on the bearing housings or pedestals of gas turbines and driven equipment using fluid-film bearings. They assume that the measurements are in-sit

This part of ISO 10816 encompasses machines which may have gears or rolling element bearings but does not address the evaluation of the condition of those gears or bearings.
