Sec. 180.415  Test and inspection markings.

    (a) Each cargo tank successfully completing the test and inspection 
requirements contained in Sec. 180.407 must be marked as specified in 
this section.
    (b) Each cargo tank must be durably and legibly marked, in English, 
with the date (month and year) and the type of test or inspection 
performed, subject to the following provisions:
    (1) The date must be readily identifiable with the applicable test 
or inspection.
    (2) The markings must be in letters and numbers at least 32 mm (1.25 
inches) high, near the specification plate or anywhere on the front 
head.
    (3) The type of test or inspection may be abbreviated as follows:
    (i) V for external visual inspection and test;
    (ii) I for internal visual inspection;
    (iii) P for pressure test;
    (iv) L for lining inspection;
    (v) T for thickness test; and
    (vi) K for leakage test for a cargo tank tested under Sec. 180.407, 
except Sec. 180.407(h)(2); and
    (vii) K-EPA27 for a cargo tank tested under Sec. 180.407(h)(2) 
after October 1, 2004.

    Examples to paragraph (b). The markings ``10-99 P, V, L'' represent

external visual inspection and test, and the lining inspection. The

cargo tank passed the leakage test under Sec. 180.407(h)(2). The 
markings ``2-00 K, K-EPA27'' represent that in February 2000 a cargo 
tank passed the leakage test under both Sec. 180.407(h)(1) and under 
EPA Method 27 in Sec. 180.407(h)(2).
    (c) For a cargo tank motor vehicle composed of multiple cargo tanks 
constructed to the same specification, which are tested and inspected at 
the same time, one set of test and inspection markings may be used to 
satisfy the requirements of this section. For a cargo tank motor vehicle 
composed of multiple cargo tanks constructed to different 
specifications, which are tested and inspected at different intervals, 
the test and inspection markings must appear in the order of the cargo 
tank's corresponding location, from front to rear.
