Test and Inspection for commercial floating fenders

Normally,large part of pneumatic rubber fenders are used for large ports, terminals or wharfs for construction and fendering purpose.They are called commercial fenders.For these type of fenders,they are inspected with following items always.

- Material test of rubber

  • Both outer rubber layer and inner rubber layers should comply the following ISO standards.

- Dimensional inspection

  • The dimensions of all the yokohama fenders shall be inspected at the initial internal pressure ( 50 KPA, 80 KPA) and the results shall be within the fllowing tolerance:

       ----- Length: + 10%, -- 5 %

       ----- diameter: + 10%, -- 5 %

Note" the diameter shall be botained from the average of at least two different measurements taken at the middle of the cylindrical section of the fender.

- Air Leakage test

The air-leakage test shall be conducted on all fenders at initial pressure for more than 30 min, and the test results shall confirm that there is no air leakage.

- Hydrostatic-pressure test

The hydrostatic-pressure test shall be performed for 10 min at the hydrostatic pressure shown as"Test pressure at 0% deflection" in Table 4 or Table 5 and there shall be no leakage of water and no defects during the test.

The frequency of the test shall be one per 20 fenders of each size and pressure. If the customer so requests, one per order of each size and pressure if the quantity is less than 20.

Circumferential and longitudinal lengths shall be measured at 10 kPa pressure and at the test pressure shown in Table 4 or Table 5.
