ISO 8528
The standard that actually predicts performance
ISO 8528 is the international standard that defines how a generating set performs when the load changes. It is the single most useful standard for a specifier, because it describes behaviour under real conditions rather than at a steady state.
Part 5 of the standard defines four performance classes — G1, G2, G3 and G4 — based on the maximum step load the set must accept and the transient deviation permitted. A set sold as "500 kVA" tells you nothing about whether it will hold a data centre UPS through a transformer inrush. A set specified as "500 kVA, G3" does.
| G1 | Basic applications — gradual load changes, voltage and frequency deviation not critical. |
|---|---|
| G2 | General commercial standby — lighting, pumps, HVAC. The default class. |
| G3 | 70 % single-step load acceptance. Data centres, hospitals, industrial process lines. |
| G4 | Applications demanding the tightest transient response available. |
Always state the class. When you enquire, tell us which ISO 8528 performance class the application requires. We will confirm that the selected engine and alternator combination meets it, and we will prove it on the load bank before the set leaves the factory.
Quality Control Flow
Five controlled stages, zero shortcuts
Each stage has a documented acceptance criterion and a named sign-off. A set cannot advance until the previous stage has been released.
1
Incoming
Engines, alternators and key components are inspected against the purchase specification and released only on documented acceptance.
2
Assembly
Coupling, alignment, wiring and piping are completed to a written build standard and signed off station by station.
3
Testing
Four-point load bank test at 25 %, 50 %, 75 % and 100 % load. Results are recorded and issued with the set.
4
Painting
Seven-stage pre-treatment and powder coating to the specified paint system, with dry-film thickness verified.
5
Packaging
Export packing with protection, desiccant and a complete documentation pack including the test certificate.
Documentation
What ships with every generator set
Factory test certificate
Recorded voltage, frequency, load and temperature data from the four-point load bank test.
Conformity documents
CE declaration of conformity and emission type-approval reference for the applicable standard.
O&M documentation
Operation and maintenance manual, wiring diagram, spare-parts list and commissioning checklist.
