BS ISO 484-2:2015

What is ISO 484-2 - Manufacturing tolerances of ship screw propellers about?  

ISO 484-2 is the second part of the multi-series standard that is applicable to shipbuilding. 

ISO 484-2 defines manufacturing tolerances of ship screw propellers of a diameter between 0,80 m and 2,50 m. 

Who is ISO 484-2 - Manufacturing tolerances of ship screw propellers for?  

ISO 484-2 on shipbuilding is useful for: 

• The maritime industry  
• Maritime engineers/architects/surveyors/construction industry   
• Infrastructure and environmental engineers for ports  
• Project management consultants for maritime/ports  
• Port authorities  
• Private consultancies  
• Planning agencies  
• Manufacturers and suppliers of ship screw propellers 

Why should you use ISO 484-2 - Manufacturing tolerances of ship screw propellers?  

ISO 484-2 specifies the method of measurement consists in setting out along a helicoidal line of radius, r, a certain length, PQ, corresponding to the desired angle, α, and in measuring the difference, h, in the heights of the points P and Q with respect to a reference plane 

Overall, ISO 484-2 equipment and a method will help you to enable the tolerances to be verified to the required accuracy.
