Based on 49 CFR 180.415, here are the practical requirements for marking your cargo tanks after they successfully complete required tests and inspections:
* Durability and Language: Each cargo tank must be durably and legibly marked in English with the month and year of the test, along with the type of test or inspection performed. The date must be clearly identifiable with the specific test.
* Size and Placement: The markings must use letters and numbers at least 32 mm (1.25 inches) high. They must be placed either near the specification plate or anywhere on the front head of the cargo tank.
* Allowed Abbreviations: You may use the following standard abbreviations for the tests:
* V = External visual inspection and test
* I = Internal visual inspection
* P = Pressure test
* L = Lining inspection
* T = Thickness test
* K = Leakage test (under § 180.407, except § 180.407(h)(2))
* K-EPA27 = Leakage test under § 180.407(h)(2) after October 1, 2004
* Multiple Cargo Tanks:
* If your vehicle has multiple cargo tanks built to the same specification and they are tested at the same time, you only need to use one set of test and inspection markings.
* If your vehicle has multiple cargo tanks built to different specifications that are tested at different intervals, the markings must appear in the exact order of the cargo tanks' locations, running from front to rear.
