This procedure is in accordance with ASME Section XI, and'is applicable to the editicn and cdc'enda snecified in the Examination Program, in accordance with OPS-P50-101. Technical contents are I ased on the l',SME Code, including Section XI IWA-2240 when dictatcd due te code omissions and to-iicplcnent upgraded tech-nalogy or good practice. Procedura 0FS-flSD-101, i'rcscrvice and Inservice Examination Data Rcrorting is considered part of this procedure and.is to be used as applicable.

2.3 Operators perfencing escainations to this procedure will be qualified to Level IT in accordance with SitT-TC-1A, its supplcment and appendices as applicable for ultrasonic.testina.

Level I operators may be employed as assistants.

2.4 The area to be exaained and contacted by the search unit shall be checked to ensurc~ that ic is free of dirt, loose scale, nachining or grinding particles, ecid spatter or other loose.

foreign matter that would-impair the free n:ovement of the search unit or affect the examination. If such conditions are detected, they will be rectified prior to conductinq the examination.
