On July 1, 2025 (90 FR 28064), PHMSA published a DFR amending its regulations at 49 CFR part 192 to incorporate by reference the 2023 edition of ASTM F2145, “Standard Specification for Polyamide 11 (PA 11) and Polyamide 12 (PA12) Mechanical Fittings for Use on Outside Diameter Controlled Polyamide 11 and Polyamide 12 Pipe and Tubing.” Reference to the 2023 version of the standard will replace existing references to ASTM F2145-13, “Standard
Specification for Polyamide 11 (PA 11) and Polyamide 12 (PA12) Mechanical Fittings for Use on Outside Diameter Controlled Polyamide 11 and Polyamide 12 Pipe and Tubing,” issued May 1, 2013, within 49 CFR part 192.
PHMSA issued the DFR under the procedures set forth at 49 CFR 190.339. In accordance with those provisions, PHMSA stated in the DFR that if no adverse comments were received, the DFR would become final and effective on January 1, 2026. PHMSA did not receive any comments that warranted withdrawal of the DFR; therefore, this rule will become effective as scheduled.
