Check out IPC-A-600. Revision G (July 2004) section 3.2.3 (surface) and section 3.2.4 (internal) give min/max thicknesses for various weight copper. The min also changes depending on what class (1-3) standard you are working to.

We found repeated pad lifted after different SMT Reflow temperature (eg: 243 deg C and 233 deg C) at an isolated slot. The PCB Supplier had claimed that such condition is acceptable as per IPC 600H Clause 3.3.2 (Cross Sections) - eg: Acceptable - C
