CommentsSee 184.108.40.206 and 5.7.1, figure 5.7 A and figure 5.8 for the telltale holes in shell reinforcing plates and 7.3.4 for the use of these holes. See appendix T for a table of inspections required
For bottom and cone roof re-pads, seal welding is the preferred detail. For floor pads, vacuum test the welds. For cone roof repads a visual inspection is usually all that is needed.
