MIL AS23190A
MIL AS23190A is an aerospace-grade standard published by SAE International's AE-8C2 Terminating Devices and Tooling Committee, establishing performance and testing requirements for plastic and metal cable ties, straps, clamps, and mounting hardware used in cable harness tying and support applications. Formerly designated MIL-S-23190E under the US Military Specification system, this standard was transitioned to SAE as part of the Department of Defense's broader shift toward performance-based industry standards. Presto tensile testing machines help manufacturers ensure that cable ties and straps meet MIL-AS23190A standards.
Significance
Cable ties and harness support hardware used in aerospace, defense, and industrial assemblies must withstand extreme mechanical, thermal, and environmental stresses throughout their service life. MIL AS23190A provides a rigorous, performance-based testing framework—including minimum loop tensile strength testing, temperature cycling from -65°C to +135°C per MIL-STD-202. Method 107, and shock and vibration resistance—ensuring that cable management components retain their structural integrity and locking function under operational extremes. Ensuring compliance is critical for manufacturers providing their services for defense contractors, aerospace OEMs, and military procurement programs. This standard applies to cable harness organization and support plastic and metal straps, adjustable tie-down straps, loop clamps, cushioned clamps, and related hardware. The key mechanical performance test is the minimum loop tensile test, where a cable tie is applied to a split mandrel and the force required to separate the two halves until failure is measured. Dimensional requirements are governed by the companion standards SAE AS33671 (formerly MS3367) and SAE AS33681 (formerly MS3368). The standard applies to components used in aerospace, military vehicles, and high-reliability electronic assembly environments.Scope
