29、t and evaluation of mechanical vibrations1 ScopeThis document describes a procedure for measuring and evaluating the external mechanical vibration behaviour of generating sets at the measuring points stated in this document.It applies to RIC engine driven a.c. generating sets for fixed and mobile in
30、stallations with rigid and/or resilient mountings. It is applicable for land and marine use, excluding generating sets used on aircraft or those used to propel land vehicles and locomotives.For some specific applications (essential hospital supplies, high rise buildings, etc.) supplementary requirem
31、ents may be necessary. The provisions of this document are intended to be regarded as a basis for such applications.For generating sets driven by other reciprocating-type prime movers (e.g. sewage gas engines, steam engines), the provisions of this document are intended to be regarded as a basis for
32、 such applications.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

40、 legislative authorities, are required to be met, the authority shall be stated by the customer prior to placing the order.Any further additional requirements shall be subject to agreement between the manufacturer and customer prior to placing the order.6 Measuring devicesThe measuring system shall
41、provide the rms values of displacement and velocity with an accuracy of 10 % over the range 10 Hz to 1 000 Hz and an accuracy of 20 %/+10 % over the range 2 Hz to 10 Hz. These values may be obtained from a single sensor whose signal is either integrated or differentiated, depending on the outcome of
42、 the measuring device, to derive the quantities not directly measured, provided the accuracy of the measuring system is not adversely affected.The accuracy of measurement is also affected by the method of connection between the transducer and the object being measured. Both the frequency response an
43、d the measured vibration are affected by the method of attaching the transducer. It is especially important to maintain good attachment between the transducer and the point on the generating set being measured when vibration levels are high.2 ISO 2017 All rights reservedBS ISO 85289:2017ISO 8528-9:2
