          Subpart F_Qualification and Maintenance of Tank Cars

 

Sec. 180.515  Markings.



    (a) When a tank car passes the required inspection and test with 

acceptable results, the tank car facility shall mark the date of the 

inspection and test and the due date of the next inspection and test on 

the tank car in accordance with appendix C of the AAR Specifications for 

Tank Cars (IBR, see Sec. 171.7 of this subchapter). When a tank car 

facility performs multiple inspection and test at the same time, one 

date may be used to satisfy the requirements of this section. One date 

also may be shown when multiple inspection and test have the same due 

date.

    (b) Pressure converted tank cars must have the new specification and 

conversion date permanently marked in letters and figures at least 0.95 

cm (0.375 inch) high on the outside of the manway nozzle or the edge of 

the manway nozzle flange on the left side of the car. The marking may 

have the last numeral of the specification number omitted (e.g., ``DOT 

111A100W'' instead of ``DOT 111A100W1'').

    (c) When pressure tested within six months of installation and 

protected from deterioration, the test date marking of a reclosing 

pressure relief device is the installation date on the tank car.
