Standardised vibration criteria (VC) for sensitive equipment and machinery exist since the 1980s and describe the limits of vibration velocity for a range of sensitivity classes from A-G. The limits refer to Max-Hold values in one-third octave bands and equipment manufacturers need to define the respective limits at the site of their machines to ensure unhampered operations. When engineers are asked to determine the prevailing vibration exposure at existing locations or future sites of equipment such as microscopes, tomography or appliances in the semiconductor industry, divergent methods of data analysis can lead to substantially different site classifications if the parameters of the data processing steps are not defined by the manufacturer or set down in (international) standards. This paper shows how a collection of 15 sample records acquired in typical laboratory environments is processed by four different consultants – using their typical analysis routines – and how the resulting Max-Hold spectra apparently conform to very different VC lines. This can have considerable effects on the subsequent foundation planning and the resulting costs of insulating the footings or foundations accordingly. The authors present recommendations regarding the filtering techniques for third-octave band computations as well as the time constants to use when computing RMS-values within each frequency band.
