MIL-STD-101 Color Code For Pipelines And For Compressed Gas CylindersThis standard establishes a common color code for visual warnings to accompany the written identification of materials covered in piping systems and contained in compressed gas cylinders, and to facilitate the segregation of these cylinders at depots. This standard does not define the manner or conditions under which these materials may be used safely.

3. DEFINITIONS

3.1 For the purpose of this standard, the following definitions shall apply:

(a) Commercial colors. Commercial colors are the colors which may be used, in a limited arrangement, on a small portion of the body and bottom of a compressed gas cylinder for commercial identification and designation of ownership (See 5.2.2 and 5.2.5.1).

(b) Compressed gas cylinder. A compressed gas cylinder is any tube, bottle, or other type of pressure cylinder larger than 3 inches in diameter by 6 inches in length, which contains a pressure that exceeds 104 pounds per square inch at 130°F or any liquid flammable material having a vapor pressure exceeding 40 pounds per square inch absolute at 100°F. One---ton type bulk containers are included. All ammunition and medical gases are excluded (see NATO Standard AMedP---53 for approved color codes for medical gases).

(c) Piping systems. Piping systems consist of any pipeline or conduit used for the transport of gases, liquids, or semiliquids, but not those used for carrying solids in air or gas. Valves, fittings, operating accessories, pipe coverings, and pipe installations of any kind (including submerged or buried pipe lines, their markers or buoys, and their points of tie---in with pumping stations and storage or dispensing facilities) shall be considered as parts of a piping system. Supports, brackets, or other non---operating accessories are not considered parts for application of warning colors.
