How to place the fasteners and shafts in salt spray test chamber  

++++

Hello,

Painted panels can be hanged in test chamber but I would like know the standard practices of positioning the fasteners & motor shafts in the salt spray test chamber?

SAE/USCAR-1 requires that the orientation of the primary axis of the fastener to be 25 +/- 3 degrees from vertical. I recommend that you obtain this standard, as it describes the proper procedure for testing fasteners, and it is suitable for shaft components as well.

Painted panels should be tested at a 15 - 30 degree angle. For other parts, the significant surface should be a 15 - 30 degree angle whenever possible. Position the test specimen to minimize solution collection in crevices.
