Traduction automatique locale · Langue originale de la source
Résumé
On September 10, 2003, the Research and Special Programs Administration--the predecessor agency to the Pipeline and Hazardous Materials Safety Administration published a notice of proposed rulemaking (NPRM) to propose an inspection and testing program for early detection of sustained load cracking in certain cylinders manufactured with aluminum alloy 6351-T6. Based on comments received in response to that NPRM, we are proposing to adopt a maximum service life for cylinders manufactured with aluminum alloy 6351-T6 and to prohibit the use of these cylinders after the expiration of their maximum service life.
