GENERAL NOTES
1. All tests and inspections are to be made in accordance with NK rule.
2. Test pieces are to be taken separately from the propeller.
3. Mechanical properties of material are as follow,
Ultimate tensile strength 590 N/mm2 Elongation 16 % 0.2% proof stress 245 N/mm2
4. Finished tolerances are to be made in accordance with ISO class 1. 5. Allowable unbalanced weight shall not exceed 3.0 kg at the tips of
the blades.
6. Leading and trailing edge of the blades are to be finished accurately by
using the gauge plates.
7. Cone parts of the propeller boss are to be finished accurately by using
taper gauge.
8 .. Number of the blade is to be stamped the letters of " A,S,C, ....... "
on the periphery of the boss fore side of each blade.
And the following information is to be clearly stamped in a Diameter,
