ISO 10816-1 is the basic document describing the 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 bearings, bearing pedestals, or housings of industrial ...
You ask about the table in the standard that shows limits for different zones based on the support and power. In ISO 10816-3, this is written "r.m.s. velocity mm/s" on the table's header. In general, the vibration limit can be overall amplitude for the entire the sample or it could be spectral amplitude at a certain frequency in the spectrum plot.
to describe the vibration of a fan because it represents a fairly constant level of vibration severity independent of the fan rpm. A velocity measurement gives a vibration severity description that can be compared at any rotational speed. In contrast, displacement measures the maximum distance of a vibrating body from its neutral position.

Oct 12, 2002· in dynamic balancing of rotating machines, we have a vibration severity chart (courtesy of balmac) where we could refer for our judgement. now, is this chart we are currently using is applicable to be a reference for the completely assembled operational rotating machines? that is, the machine were mounted on different foundations and bases(i think it would not applicable to use the chart).
•Chart at right is from ISO 7919 and relates relative shaft vibration severity to shaft speed. • All vibration is relative to bearing (ie: from proximity probes ). • Shaft vibration is expressed in displacement, micrometers pk-pk • 100 micrometers ~ 4 thous of an inch. Zone Descriptions :
NOTE 1 In the past, vibration severity was often related to broad-band vibration velocity [mm/s (r.m.s.)] in the range 10 Hz to 1 000 Hz. However, different frequency ranges and measurement quantities may apply for different ma- chine types. 3.1.2 Measurement quantity

Jul 01, 2013· ISO 2372 (10816) Standards provide guidance for evaluating vibration severity in machines operating in the 10 to 200Hz (600 to 12,000 RPM) frequency range. Examples of these types of machines are small, direct-coupled, electric motors and pumps, production motors, medium motors, generators, steam and gas turbines, turbo-compressors, turbo-pumps and fans.
It provides specific guidance for assessing the severity of vibration measured on bearing housings of rotary pumps in situ and for the acceptance test at the manufacturer's test facility or in the plant. This part of ISO 10816 also gives general information and guidelines for assessing relative shaft vibration …
Initial Vibration Levels. The bar graph of the initial pump vibration level for each coupling with accurate alignment is shown in Figure 2. Overall velocity vibration levels greater than 0.157 ips-P are classified as a "slightly rough" running machine per the general machinery vibration severity chart [2].
