3.5.1 Contractor shall make welder certifications available to the Coast Guard

Contract Administrator prior to contract award.

3.6 Air Pressure Test: Contractor shall conduct an air pressure test on the blade section

Test shall be conducted at 3 PSI for a period of 30 minutes. During that time period contractor shall check for any signs of leakage through the blade surface, paying particular attention to welded areas. Soapy water solution is suggested for detection of leaks. Any leaks found shall be ground out and weld repaired with an additional air pressure test conducted.

3.6.1 Test Report: Upon successful completion of test, contractor shall provide an

Air Pressure Test Report for each rudder produced under the contract. Report shall be packed with the tested rudder with a copy of each report turned over to the Coast Guard QA Representative.

Report shall contain the following information as a minimum:

a) Contractors Name and address

b) Contract Number

c) Test description, pressure, time period.

Note: This report may be combined on a contractor’s overall inspection and test report.

3.7 Passivation Treatment: Contractor shall conduct a chemical passivation treatment on each completed rudder for the removal of free iron and other exogenous matter.

Passivation process shall be in accordance with ASTM A967, which replaces QQ-P-35 cited in drawing General Note 4. The type of passivation treatment utilized shall be as specified in Figure X1.1 of ASTM A967 for the grade of stainless being treated. Passivation shall be conducted after completion of all other manufacturing process. Passivation shall be conducted over 100% of the blade and shaft surface areas, which shall also include the blade inside cavity surfaces.

3.7.1 Test Method: After completion of the passivation process, a Copper Sulfate

Test (Practice D), or a Free Iron Test (Practice F) in accordance with ASTM A967 shall be conducted on each rudder to ensure that the process used successfully removed all free iron and other exogenous matter on treated surfaces.

a) The passivation and test process shall be repeated on any rudder showing the presents of remaining free iron and other exogenous matter on treated surfaces.

3.7.2 Test Report: Upon successful completion of test, contractor shall provide a

Passivation Treatment Report for each rudder produced under the contract. Report shall be packed with the tested rudder with a copy of each report turned over to the Coast Guard QA Representative.
