5.7 DETERMINATION OF RELEVANCY. All indications in weld craters shall be considered relevant and shall be evaluated in accordance with the applicable acceptance standards. Indications caused by marking methods such as scribe lines and vibro-etchings can be considered non- relevant unless the inspector has reason to believe that the marking is masking a relevant indication. For other indications that are believed to be non-relevant, the following methods may be used to prove non-relevancy. a. Not less than 10 percent of each type of indication shall be explored by removing the surface condition believed to have caused the indications and retested. The absence of indications under reinspection by liquid penetrant after removal of the surface condition shall be considered to prove that the indications were non-relevant with respect to actual defects. If reinspection reveals any indications, these and all of the original indications shall be considered relevant. b. Other methods for determining non-relevancy shall be approved by the authorized representative of NAVSEA.
