Measured
in microns.
A grease-depth reading at every access point opened, before and after works — reported as numbers against the AIRAH Best Practice Guideline benchmark, not as adjectives.

Kitchen exhaust program · AS 1851-2012
Kitchen exhaust compliance, maintained with certainty.
The whole system — canopy, filters, plenum, ductwork, riser and fan — maintained on a planned interval program and certified to AS 1851-2012 with the measurements on the page.
Measured
The same position,
before and after.
Every position re-shot after works from the identical position and framing, one label per pair — comparable evidence, not two unrelated pictures.
Full or partial,
stated first.
Whether the whole system was serviced or only part of it is written on the certificate before anyone asks, with every unreached section listed and the reason.
Every deficiency,
numbered.
Missing access panels, sections beyond criteria, damaged ductwork — each listed with location, severity, a photo reference and a recommended action.
The next service,
set before we leave.
Your interval is set from the measured accumulation between services and written on the certificate. The obligation never floats.
Start
Put your exhaust on a measured program.
Start with a 15–30 minute site survey — the same instruments and the same evidence discipline as the certificate, on your own kitchen.
