MIL-STD-161G
3. DEFINITIONS
3.1 Piping system. A piping system consists of any pipelines or part thereof used to convey liquid petroleum products including heating fuel and hydrocarbon missile fuels. This may be classified as tank car and tank truck loading and unloading connections; storage tank valves; pump manifold and valves; cross-country pipelines and their points of tie in with pumping stations; oil tanker connections and manifolds and other similar dispensing outlets.
3.2 Storage system. All exposed fixed storage tanks not specifically exempted in 1.2.
3.3 Title. A title is the identification required on piping systems listed in 3.1. A title should
identify the contents by complete nomenclature type/grade of product and military symbol (if established), such as Gasoline, Aviation, Grade 1OOLL. Generally recognized abbreviations may be used in lieu of the title such as AVGAS 1OOLL for Gasoline, Aviation, 1OOLL. Refer to the appropriate specification for
approved military symbols for petroleum and related products used by the Department of Defense. North
Atlantic Treaty Organization (NATO) symbols can be found in Annex C to STANAG 1135.
3.4 NATO symbol. A NATO symbol number indicates that the product is interchangeable for its intended use with a particular product produced in one or more of the NATO participating nations.
4. GENERAL REQUIREMENTS
4.1 Identification method. Bulk petroleum products and hydrocarbon missile fuels generally used in the military system have been classified and segregated by groups to facilitate the ready identification
of product groups. This method establishes, defines, and assigns a yellow band or series of bands for recognition to each of eight groups of similar type products in a distinctive and conspicuous manner, as a visual aid and a supplement to written identification. These groups are aviation gasolines, automotive gasolines, jet fuels, distillates, heavy fuel (black) oils, lubricating oils, Thermally Stable Jet Fuels, and missile fuels as shown on Figures 1 through 8, and Table I. The written identification consists of the
exact title as defined in 3.3; the NATO symbol as prescribed and defined in 4.5 and figure 9; the color band(s) will be as indicated in 5.1.3. The NATO symbol of a product (if established) is required on piping and storage systems located in the United States, as well as other NATO nations.
4.1.1 Application of markings. Markings, (titles, bands, and arrows), will be applied by painting and stenciling or, if desired, by means of decals, elastomeric film or reflectorized sheeting. If decals, film, or sheeting are used, material shall conform to specification MIL-M-43719 or ASTM-D4956 as applicable. In addition to the locations indicated in the subsequent paragraphs, markings shall be applied at all receiving connections; where line connections are made to manifolds, and at any other location necessary to assure ready identification of the product in the system. For single product, isolated systems, only the line into a manifold shall be marked. For multiproduct systems, product identification markings shall be placed on the inlet multiproduct line and all manifold outlet lines.
4.2 Color Specification. The colors assigned in the standard shall conform in hue and chroma to the requirements identified by numbers specified in FED-STD-595.
4.3 Employment of colors.
4.3.1 Warning color. The color Yellow No. 13655 is assigned as a primary warning for all flammable materials in accordance with the provisions of the basic color code, MIL-STD-1O1. Petroleum products and hydrocarbon missile fuels are considered falling within this classification of materials.
4.3.2 Use of black and white colors. The colors Black No. 17O38 and White Gloss No. 17875 are assigned, WITHOUT SIGNIFICANT MEANING, for general use as indicated in this standard.
