Hello dear colleagues, this is an extract of API 650 2013 " 7.3.6.8 Internal bottom elevation measurements shall be made before and after hydrostatic testing. Measurements
shall be made at maximum intervals of 3 m (10 ft) measured on diametrical lines across the tank. The diametrical
lines shall be spaced at equal angles, with a maximum separation measured at the tank circumference of 10 m (32 ft).
A minimum of four diametrical lines shall be used."; I ask, Can we use it for measure the bottom flatness?, it doesn't mention any tolerance, is there any tolerance that can I use for reference?
