Industry Standards: ISO-484

The International Organization for Standardization (ISO) is a worldwide federation of national standards bodies. This organization has produced 'ISO-484' that defines the standards of manufacturing tolerances for marine propellers. AccuTech technicians use this standard to inspect propellers and provides ISO compliance which gives you quality workmanship and peace of mind.

ISO-484 is catagorized as follows:

Class Manufacturing Accuracy

S

Very High Accuracy


I

High Accuracy


II

Medium Accuracy


III

Wide Tolerances


Traditionally, classes 'S' and 'I' were only used on special vessels due to the extreme accuracy and precision. However, Prop Scan has made these classes available to all, providing economical resolution to everyone's propeller problems.

A Class of its Own: Due to Prop Scan's high levels of accuracy and repeatability it is now possible to repair a propeller to an accuracy level that is twice the accuracy of Class S. This classification is known as Class O.
