ISO 484/2

In 1981, the International Standard Organization (ISO) set the standards for propellers, i.e. the allowed tolerances for pitch deviations for certain classes of propellers.
This allowed the propellers to be classified by quality.
Anyone who expects maximum and optimal performance from their boat should strive to have a Class I or Class S propeller.

With an appropriate and optimized propeller, the vibrations will disappear and the power expended on the vibrations will be used more usefully, i.e. it will be used to power the ship.
The result is triple, higher speed, reduced fuel consumption and a more comfortable ride.

Prop Scan  EPS  (Enhanced Propeller Standard)

ISO organization has adopted Standards for tolerance of propeller accuracy at a time when propellers could not be measured electronically and defines standards only for propellers with a diameter over 800 mm.

Prop Scan EPS - (improved propeller standard) is used in optimization and modification of propellers, and was developed by experts in the field to further improve the ISO 484 standard.

Prop Scan EPS can measure propellers less than 200 mm in diameter.

In addition to local pitch measurements, Prop Scan EPS measures the complete pressure side of the propeller and displays tolerances to control the shape of the surface.

Prop Scan EPS adds an additional accuracy class to class 0

Adriatic Propeleri can optimize propellers to class 0
