2. by persons who have been trained and qualified in the established procedures and with the equipment employed in testing. [ 49 CFR 192.243(b)(2)]

C. Procedures must be established for the proper interpretation of each nondestructive test of a weld to ensure the acceptability of the weld under §1321. C [ 49 CFR 192.243(c)]

D. When nondestructive testing is required under §1321. B, the following percentages of each day's field butt welds, selected at random by the operator, must be nondestructively tested over their entire circumference: [ 49 CFR 192.243(d)]

1. in Class 1 locations, except offshore, at least 10 percent; [ 49 CFR 192.243(d)(1)]

F. When nondestructive testing is required under §1321. B, each operator must retain, for the life of the pipeline, a record showing by milepost, engineering station, or by geographic feature, the number of girth welds made, the number nondestructively tested, the number rejected, and the disposition of the rejects.
