confidence that 5% or less defcetive attributes exist in the unexn=ined portion of the population under evaluation.

6.1.2 The plan for non-critical attributes shall ensure 95%

confidence that 15% or less defective attributes exist in the unexamined portion of the population under evaluation.

.6. 2 Sa=ples will be drawn from defined lots consisting of one or more work control packages (travelers, drawings, etc.).

NOTE: When ite=s selected are found to be inaccessible. they vill be excluded from the sample and an alternate item selected.

6.3 For items or systems that have been turned over to Illinois Power Cc:pany (IPC), Field Verification vill require interface and coordination with the IPC Start-Up Coordinator in accordance with Reference 3.5.

6.4 Sampling is not permitted on lots retuYned to BAFV by the IPC Overinspection Progran for re-examination.

7.2 Lot si:e fer structural steel shall be deternined as follows.

7.2.1 The SQAE or his designec shall request structural drawings from the Document Control Center for the arca(s)/ build-ing(s). Lot si:c(s) may consist of the number of structural members in cach main framing elevation plus other members located within the building, but not on a main framing elevation:
