MIL-PRF-24758 Conduit Systems, Flexible, WeatherproofThis specification covers the performance requirements for weatherproof flexible conduit systems \(see 6.3.12\) for use primarily in exposed areas \(see 6.3.10\) on U.S. Navy ships, to shield against electromagnetic \(EM\) radiation from own-ship transmitters and emissions external to the ship, electromagnetic pulse \(EMP\) \(see 6.3.8\) events, and to minimize corrosion \(see 6.3.6\) while being field repairable to reduce maintenance.

cited herein, the text of this document takes precedence. Nothing in this document, however, supersedes applicable

laws and regulations unless a specific exemption has been obtained.

REQUIREMENTS

3.1 Measurement units. English units shall be used to the maximum extent possible followed by the metric

equivalent.

3.2 First article. When specified (see 6.2), a sample shall be subjected to first article inspection in

accordance with 4.2.

3.3 Materials. Materials shall be used which will enable the assemblies to meet the performance

requirements of this specification. The external finish of fittings and constituent parts shall be dull and non-

reflective. The external finish on the conduit shall be paintable or ship gray in color. Materials used for end fittings

shall be interchangeable with like components and mate to existing hardware currently employed aboard U.S. Navy

ships.

Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or

3.3.1

environmentally preferable materials should be used to the maximum extent possible provided that the material

meets or exceeds the operational and maintenance requirements, and promotes economically advantageous life cycle

costs.
