MIL-PRF-24758A(SH)
6.3.
Definitions. The definitions specified in ANSI/IEEE 100 and 6.3.1 through 6.3.19 apply.
Commercial and government entity (CAGE). A five-position code that identifies companies doing or
6.3.1
wishing to do business with the U.S. Federal Government.
Conduit fitting. A device designed to join or terminate one or more portions of a conduit installation.
6.3.2
Conduit joint. An interface between two or more components of a conduit system, or between a
6.3.3
conduit system and another piece of equipment.
Constituent parts. Any device used to join together two fittings, which differ in diameter, thread size,
6.3.4
or thread type. Such constituent parts include end fittings, panel fittings, threaded pipe fittings, tapered pipe fittings,
kick pipes, and stuffing tubes.
Conduit system. The physical makeup of a section of conduit with an end fitting attached to each end,
6.3.5
one of which being a swivel fitting.
Corrosion. A specific type of deterioration resulting in damage or impairment of metals or metallic
6.3.6
parts as the result of attack by moisture, air, acid, alkali, chemicals, or electrochemical action.
Design activity code. The design activity CAGE code is part of the item identification number and
6.3.7
where the manufacturer is not the design activity, both the manufacturer and the subcontractor CAGE codes are
required on the item except for military specification or approved standard parts. If the CAGE code and the part
number are applied on one line, a dash or virgule separates the number from the code.
Electromagnetic pulse (EMP). A transient, high-intensity electromagnetic field, EMP is commonly
6.3.8
associated with nuclear explosions in or near the Earth's atmosphere. However, EMP can arise from other sources,
such as lightning.
Environmental conditions. Flexible conduits, conduit fittings, and constituent parts supplied under this
6.3.9
specification perform in a shipboard exposed (see 6.3.10) environment, and have an initial shielding effectiveness
minimum of 56 decibels (dB), with service performance minimum of 40 dB after an expected service life of at least
12 years. This requires a performance degradation of no more than 1.3 dB/yr.
Exposed areas. Installations that are not protected from the external environment.
6.3.10
6.3.11 External influences. Examples of external influences are the presence of water, low and high
temperatures, corrosive or polluting substances, and solar radiation.
6.3.12 Flexible conduit. A conduit which can be bent by hand with a reasonable small force, but without any
other assistance, which is intended to flex frequently throughout its service life without significant loss of its
characteristics, and if suspended at its ends may be approximated by a catanary curve.
6.3.13 Greenwater loading. A mechanical loading due to wave slap. (The requirement is 6.09 pounds per
square inch (PSI) (42 kilopascal) for surface craft.)
6.3.14 Halogen free conduit. A conduit that on combustion produces a low level of acid gas emission. (The
level of acid gas evolved by conduits calculated as hydrochloric is not greater than .0001764 oz (5 mg) of
hydrochloric acid per gram of sample, reference IEC 60614-1 clause 11.2.1.)
6.3.15 Identifying number. The identifying number is as specified in the acquisition document. The
identifying number may be a part number as defined in DoD 4120.3-M and in ASME Y14.100, Appendix B,C,D,
and E, a type number, a type designation, or a number identifying a definitive acquisition document, which specifies
the requirements for the part and the applicable CAGE codes of the manufacture and design activity. All parts may
