Not a complete catalogue
The first release contains four reviewed Australian-current standard-ISO families. A no-match result does not mean no suitable nozzle exists.
Limits
What this finder does not establish.
A narrow answer with explicit unknowns is more useful than a broad answer built on guessed transitions or copied catalogues.
No interpolation
If JKI says Very Coarse at 2 bar and Medium at 6 bar, BecSpec does not assign a class at 3, 4 or 5 bar without separate exact evidence.
No special hardware shortcut
Air/liquid systems, rotary atomisers, Albuz TVI, AirJet/Airtec, complete sprayers and other special/non-ISO geometries require direct technical evidence and are not automatically matched.
No APVMA inference
The finder does not extract or guess label requirements. The user must copy the current water rate and droplet instruction from the approved label.
No measured-flow claim
The hydraulic output is nominal engineering sizing. Wear, pressure loss, plumbing, tip condition and calibration affect actual output.
No supplier guarantee
“Current in Australia” reflects a frozen family-level availability check. It is not live stock, price or dealer inventory.
