The Contractor will then conduct ultrasonic testing at each test spot using an ultrasound thickness gauge. All testers shall be qualified in using an ultrasound thickness gauge for ultrasonic testing and have appropriate certification for this testing being performed. When pitting or pops are presents, the ultrasonic tester will need to furnish the correct equipment to take an accurate measurement. The Contractor cannot move test points due to the lack of proper instruments. At the conclusion of the ultrasound testing, all test spots that were taken down to bare white metal will need to be repainted as identified in paragraph SP-

11 and be incidental to this bid item.

A written record of each of these readings and a report of findings shall be provided to the Government Quality Assurance Representative and the Contracting Officer’s representative.
