Surface evenness testing
Vanes, flap valves
tightness.
All surfaces which come
in contact with each other shall be first degreased (with cleaning rags
N 120 preferably, or cleaning rags N 106A) then allowed for drying.
Be sure no fluorescent
indication (coming from white rags for instance) is visible.
