Those which are ordinarily considered suitable for use with this specication are given below. When methods involving high temperatures are used in the removal and repair of discontinuities, the casting shall be preheated to at least the minimum temperature in Table 4. All castings shall receive the specified heat treatment requirement: Unacceptable visual surface discontinuities shall be removed and their removal veried by visual examination of the resultant cavities.
