Reciprocating Compressor System Vibration Evidence Worksheet
Organize applicability, system-boundary, measurement and source evidence for qualified review against ISO 20816-8:2018. This worksheet checks documentation completeness and the verified public scope only; it does not calculate a vibration class, condition diagnosis, alarm, trip setpoint, monitoring interval or operating instruction.

Standard and source register
| ID | Source and lifecycle | Verified public support | Not supported publicly |
|---|---|---|---|
| S1 | ISO 20816-8:2018 Edition 1 – published August 2018 – confirmed 2024 – stage 90.93 | System/fatigue purpose; rigid foundation; typical speed; operational basis; covered examples; driver, shaft, hyper-compressor, internal-diagnostic, condition-monitoring and noise boundaries. | Numerical criteria, exact groups, quantity/statistic, locations/directions, bands, boundary rules, combination method, alarms, trips, intervals and operating actions. |
| S2 | ISO 10816-8:2014 Edition 1 – withdrawn 10 August 2018 – revised by ISO 20816-8:2018 | The direct predecessor lifecycle and its broadly similar former public scope. | No proof that any former numerical table, measurement detail, semantics or actions are unchanged in the current document. |
| S3 | ISO 20816-3:2022 Edition 2 – published and current | Part 3 explicitly excludes reciprocating compressor systems and routes them to ISO 20816-8. | Part 3 machine groups and numerical criteria cannot be transplanted to a Part 8 system or used as a normative web comparison. |
Review notes
Why does this page no longer output vibration Class A, B, C or D?
The former values lacked a checked licensed ISO 20816-8:2018 clause/table, exact system group, complete measurement definition and verified boundary convention. A numerical class would therefore be unsupported.
Does ISO 20816-8 exclude piping vibration?
No blanket exclusion is supported. The official abstract says the values help avoid fatigue problems in piping and mounted equipment and protect directly mounted pipe systems. A separate pulsation/mechanical study can still be required for broader piping risks.
Can the classification be used for condition monitoring or internal fault diagnosis?
The official abstract explicitly says the guidelines are not intended for condition monitoring and warns that internal valve, piston and ring problems may require investigative diagnostics outside scope.
Are compressors outside 120 to 1 800 r/min automatically excluded?
No. That interval is described as typical. The general guidelines can be used outside it, but the official abstract warns that different evaluation criteria might be appropriate.
Can this worksheet recommend continued operation, monitoring frequency, 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, table, coefficient or class boundary is copied or inferred. The former numerical classifications, flexible-foundation extrapolation and operating advice were removed because their current normative basis and complete application conditions were not verified.
