# Nondestructive Testing **Citation:** 192.243 **Type / status:** regulation / current **Agency:** Arkansas Public Service Commission **Effective:** Not stated **Published:** Not stated § 192.243 Nondestructive Testing (a) Nondestructive testing of welds must be performed by any process, other than trepanning, that will clearly indicate defects that may affect the integrity of the weld. (b) Nondestructive testing of welds must be performed: (1) In accordance with written procedures ## Document text § 192.243 Nondestructive Testing (a) Nondestructive testing of welds must be performed by any process, other than trepanning, that will clearly indicate defects that may affect the integrity of the weld. (b) Nondestructive testing of welds must be performed: (1) In accordance with written procedures; and (2) By persons who have been trained and qualified in accordance with the requirements of API Standard 1104. These persons must also be qualified on the equipment employed in the nondestructive testing. (c) Procedures must be established for the proper interpretation of each nondestructive test of a weld to ensure the acceptability of the weld under § 192.241(c). (d) When nondestructive testing is required under § 192.241(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: (1) In Class 1 locations, at least 10 percent. (2) In Class 2 locations, at least 15 percent. (3) In Class 3 and 4 locations at crossings of major or navigable rivers and within railroad or public highway rights-of-way, including tunnels, bridges, and overhead road crossings, 100 percent unless impracticable, in which case at least 90 percent. Nondestructive testing must be impracticable for each girth weld not tested. (4) At pipeline tie-ins, including tie-ins of replacement sections, 100 percent. (e) Except for a welder or welding operator whose work is isolated from the principal welding activity, a sample of each welder's or welding work for each day must be nondestructively tested, when nondestructive testing is required under § 192.241(b). (f) When nondestructive testing is required under § 192.241(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. ## Provenance - Official: Yes - Source: - Source ID: `ar-car-pipeline-safety` - SHA-256: `b03a59b7058df12b2faa6c580d2a84a92fcca007c25b7e09afde14e95fe165e2` - Retrieved: 2026-08-12T08:10:37.612Z - Exported: 2026-08-24T01:45:06.290Z - Document slug: `ar-car-23-500-192-243` ### Source metadata ```json { "jurisdiction": "US-AR", "subject": "intrastate-gas", "caveats": { "exactScope": "The searchable corpus contains every current numbered section, the code-wide definitions, and every operative appendix in official 23 CAR Part 500, plus direct pipeline rules 15 CAR sections 275-406 and 275-504.

AOGC section 275-406 separately reaches specified producer or producer-affiliated natural-gas systems.
