Bureau veritas carried out the per-shipment inspection for 39pcs cylindrical fenders 1000mmODx500mmIDx1000mmL in our factory dated 10-11 Oct. Inspection details includes visual dimensional, performance test, physical properties test of rubber, documents view.

1, visual dimensional

5pcs check at randomly, there is no obvious defect was found on the surface, the whole surface were in good condition.

Below is the dimension result of 5pcs

Out diameter(mm)	Inner diameter(mm)	Length(mm)
1010	510	1003
994	500	996
1005	510	1006
1000	510	999
1000	510	1003
