NOTE: KSC-SPEC-Z-0008 does not address the use of AL6XN tube material. All requirements in KSC-SPEC-Z-0008 shall apply to AL6XN tubing except the following:

The test ball size used for checking the tube inside diameter after bending shall be 0.344" for 1/2"x0.049" wall tube and 0.250" for 3/8"x0.035" wall tube. Note: These tube sizes are not presently used for this project.

A schedule showing all tubing sizes and thicknesses shall be developed by the Contractor.
