MIL-STD-1247 Markings, Functions And Hazards Designations Of Hose, Pipe, And Tube Lines For Aircraft Missile, And Space SystemsThis standard establishes material labeling requirements for identification, function, subfunction, pressures, hazards and direction of flow for pipes, hoses and tube lines used in aircraft, missile, space systems, and support equipment. The use of colors, words and symbols to identify the functions of such items to include approved abbreviations, and the dimensions of labeling items such as tags, tapes, and bands, are specifically prescribed see 4.1.1.

6. NOTES

(This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.)

6.1 Intended use. This standard is intended for use as a guideline for markings, function and hazard designations of hose, pipe, and tube lines to facilitate material labeling requirements for identification in Aircraft, Missile, Space Systems and Support Equipment. This standard is designed to result in rapid servicing of functional systems to return them to full operation and are an integral part of the complete system.

6.2 Acquisition requirements. Acquisition documents should specify the following:

a. title, number, and date of the standard.

6.3 Metrication. Whenever inch/pound dimensions are used in this standard, metric equivalents, in accordance with FED-STD-376 are acceptable.

6.4 International standardization agreements. Certain provisions of this standard are the subject of international standardization agreements (See ASIC AIR STD 17/3, STANAG 3104 and SEASTAG 3104). When change notice revision, or cancellation of this standard is proposed that will modify the international agreement concerned, the preparing activity will take appropriate action through international standardization channels, including departmental standardization offices, to change the agreement or make other appropriate accommodations.
