Hydraulic Machine Vibration Evaluation Evidence Worksheet
Organize applicability, measurement and source evidence for qualified review against ISO 20816-5:2018. This worksheet checks documentation completeness and the verified public scope only; it does not calculate a vibration zone, diagnosis, alarm, trip setpoint, acceptance result or operating instruction.

Standard and source register
| Ідентифікатор | Source and lifecycle | Verified public support | Not supported publicly |
|---|---|---|---|
| S1 | ISO 20816-5:2018 Edition 1 – published July 2018 – confirmed 2024 – stage 90.93 | Plant/configuration scope; typical speed and bearing construction; type/orientation/location dependency; ten exclusions; Purpose A/B; machine-set versus external-source vibration. | Protected Annex A ranges and mapping, numerical criteria, exact bands/amplitude conventions, boundary/combination rules, alarm/trip relationships and operating guidance. |
| S2 | ISO 10816-5:2000 Edition 1 – withdrawn 20 July 2018 – revised by ISO 20816-5:2018 | The non-rotating-part predecessor lifecycle. | No proof that its former tables, bands, limits or actions are unchanged in the current combined standard. |
| S3 | ISO 7919-5:2005 Edition 2 – withdrawn 20 July 2018 – revised by ISO 20816-5:2018 | The rotating-shaft predecessor lifecycle and its historical public framing. | No current power threshold, speed ceiling, shaft criterion, boundary rule or operating action can be transplanted from the withdrawn record. |
Review notes
Why does this page no longer output Zone A, B, C or D?
The former thirty boundary applications lacked a checked licensed ISO 20816-5:2018 clause/table, exact Annex A unit and normal-range mapping, location-specific conditions and verified boundary convention. A numeric zone would therefore be unsupported.
Which machine-set configurations are listed publicly?
The official abstract lists generators driven by hydraulic turbines, motor-generators driven by pump-turbines, motor-generators driven by hydraulic turbines and separate pumps, and pumps driven by electric motors. Plant context and the motor-use exclusion must still be checked.
Is 60 to 1 000 r/min an automatic applicability boundary?
No. The public record describes that interval as typical and says the current database mainly covers 60 to 750 r/min, with only a very small sample at 1 000 r/min. The exact normal range for a covered turbine type is in protected Annex A.
Are water-lubricated or rolling-element-bearing units covered?
No. Both configurations are explicitly excluded from ISO 20816-5:2018 in the official public abstract.
Can this worksheet recommend continued operation, maintenance, load restriction or shutdown?
No. It only checks whether a documentation package is complete enough for licensed external evaluation by an accountable qualified reviewer.
Source access: 17 July 2026. No closed ISO clause, Annex text, table, coefficient or zone boundary is copied or inferred. The former automatic classifications and operating advice were removed because their current normative basis and complete application conditions were not verified.
