Hello,

As a vibration analyst, what are the most common standards that you use with clients/vendors/service providers, etc?

Being retired, I’m not longer in an active diagnostics role but when I was the suite of API and ISO specifications generally took care of my needs.

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 2: Land-based steam turbines and generators in excess of 50 MW with normal operating speeds of 1500 r/min, 1800 r/min, 3000 r/min and 3600 r/min
— 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 sets with fluid-film bearings
— Part 5: Machine sets in hydraulic power generating and pumping plants
— Part 6: Reciprocating machines with power ratings above 100 kW
— Part 7: Rotodynamic pumps for industrial applications, including measurements on rotating shafts
— Part 8: Reciprocating compressor systems
— Part 21: Horizontal axis wind turbines with gearbox
-------


Which one of these do you use?

I assume you used several of API 6XX but possibly more frequently those for the gearboxes.

Can you pin point which ISO standards were more referenced in your jobs?

Mainly the iso10816 family. I use 10816-3 on most of my machines to begin with setting alarms but then revert to band alarms and envelope alarms once I have some trend data established.

for my industry, parts 1-3 and 6, now I thing i should take a look at parts 7 and 8, also use the iso7919 1-2 and ISO8528-9

Only ever once quoted ISO Fault level and that was on a 660Mw generator. The rest of the time its trends that guide me

Personally, I like the "new nickle" standard.

Is that putting a nickle on its edge on a machine and if it stays upright its good if it falls over its bad?

Thank you very much. I've tried to consolidate all standards mentioned in these posts and the summary is below. The boldface is for repeated mentions.


API 610 Centrifugal Pumps for Petroleum, Petrochemical and Natural Gas Industries

HI 9.6.4 Rotodynamic Pumps for Vibration Measurements and Allowable Values

ISO 7919-1:1996 Mechanical vibration of non-reciprocating machines — Measurements on rotating shafts and evaluation criteria — Part 1: General guidelines

ISO 7919 1-2  Mechanical vibration — Evaluation of machine vibration by measurements on rotating shafts:  Part 2: Land-based steam turbines and generators in excess of 50 MW with normal operating speeds of 1 500 r/min, 1 800 r/min, 3 000 r/min and 3 600 r/min

ISO 8528-9:2017 Reciprocating internal combustion engine driven alternating current generating sets — Part 9: Measurement and evaluation of mechanical vibrations
