Certifications/Approvals for Raychem NT-MIL Shrink Tubing
Series | UL | Military | Raychem |
---|---|---|---|
NT-MIL | – | AMS-DTL-23053/1*, Classes 1 & 2 | RW-3030 |
AMS-DTL-23053/1*, Classes 1 & 2
AMS-DTL-23053/1 is a specification used for classifying heat shrinkable tubes (also known as shrink sleeves) that are employed for electrical insulation, protection, and marking of wires, cables, and other electrical components. Developed by the U.S. military, this standard meets the criteria established by the Defense Logistics Agency (DLA) of the U.S. Department of Defense.
The AMS-DTL-23053/1 standard includes two main classes of heat shrinkable tubes: Classes 1 and 2. These tubes are primarily used for electrical insulation of wires and cables. Made from high-quality materials, they offer excellent protection against moisture, chemicals, abrasion, and environmental elements. The tubes shrink when heated, tightly fitting around the covered wire or cable.
The tubes are designed to meet stringent performance requirements, including resistance to temperature extremes, tensile strength, shrink ratio, and other key properties. AMS-DTL-23053/1 tubes are widely used in applications where reliable electrical insulation and protection are critical, such as in the aerospace, defense, and military industries.
