MIL-DTL-24640 Test

For Navy shipboard uses, low-smoke, lightweight electrical cables are covered under the MIL-DTL-24640 cable specification. Electrical cable testing can establish voltage and temperature ratings and assure that items fulfill the detail, performance, and design criteria.

Our lab at VTEC Laboratories has a wide range of environmental, chemical, mechanical, and electrical test capabilities that can be altered, increased, or improved to suit your applications’ requirements.

What Are the Specifications for MIL-DTL-24640 Cable?

The MIL-DTL-24640 cable specification covers electrical cables that are low-smoke and lightweight and are used aboard Navy ships. There are several different constructions of the M24640 shipboard cable available, including shielded or unshielded, waterproof, non-watertight, and watertight with circuit integrity.

With a voltage rating of up to 600 volts, parts are available with temperature ranges ranging from minus 20 degrees Celsius to 105 degrees Celsius. This cable is available in 20 or 26 American Wire Gauge and can contain two too many conductors (AWG).

Testing Services for MIL-DTL-24640

If cables adhere to the M24640 Federal Specification, VTEC can know by glancing at the item number. The following categories can be used to group M24640 part numbers:

Blank cable or not shielded cable is denoted by the letters “N,” “D,” and “O,” respectively, while an overall shield is denoted by the letters “O.”

Unarmored cable has the letter “U” and shipboard cable with armor has the letter “A.”

Number dashed With each specification document, part numbers can be made even more exact. Following the slant sheet number is the dash number, which refers to a different cable variety.

Sheet of specifications number: Each part number is followed by a number, which represents the cable’s slant sheet, and a backslash. In-depth details about things like building supplies can be found here.

Federal requirements: Each part number starts with M24640, indicating that it complies with MIL-DTL-24640 requirements.
