PART 180_CONTINUING QUALIFICATION AND MAINTENANCE OF PACKAGINGS--Table 
 
          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.
