Test fixed-type bearings for compression. 2. Test expansion-type bearings for compression and initial static coefficient of friction. Proof test 1 bearing from each lot of production bearings. A lot of bearings is 25 bearings, or fraction thereof, of the same type within a load category. The Engineer selects random test samples from each lot of production bearings. Notify the Engineer at least 7 days before starting proof testing. If proof tests cannot be performed at the specified load, perform the additional physical tests described in the testing plan in the presence of the Engineer. The tests must demonstrate that the requirements for proof testing at the specified load are satisfied. Before proof testing, the test bearings must be conditioned for 12 hours at 75 ± 5 degrees F. Clean the bearing surfaces before testing. For compression testing of PTFE spherical bearings: 1. Rotate the bearings at the design rotation or 0.02 radians, whichever is greater, and hold for 1 hour at a load of 1.5 times the maximum vertical load capacity. You may rotate the bearing by inserting a beveled plate between the bearing and the restraining surface before loading. 2. Maintain the bearing in a rotated position during testing. For coefficient of friction testing of PTFE spherical bearings: 1. Continuously load the bearing to the minimum dead load for 12 hours before testing. Maintain the dead load during testing. 2. Measure the initial static coefficient of friction on the 1st movement of the bearing. 3. Measure the initial static and dynamic coefficients of friction at a sliding speed of not more than 1 inch per minute. The initial static friction must not exceed that specified. 4. Cycle the test bearings for a minimum of 100 movements. Each movement must consist of at least 1 inch of relative movement at a sliding speed of not more than 12 inches per minute. After cycling, measure the initial static and dynamic coefficients of friction at a sliding speed of not more than 1 inch per minute. The initial static friction must not exceed that specified. Proof-tested bearings must not show any signs of the following: 1. Bond failure of bearing surfaces 2. Separation or lift-off of plates from each other or from PTFE surfaces 3. Excessive transfer of PTFE to the stainless steel surface 4. Other defects If a proof-tested bearing fails to comply with the above requirements, proof test all the remaining bearings in the lot B Materials B(1) General Welding must comply with AWS D1.1 except welding of stainless steel must comply with AWS D
