TIA TIA-455-12-B

Abstract

<strong>Intent</strong> <br>The intent of this test is to establish the ability of a fiber optic component (cable, connecting device, etc.) to resist degradation when exposed to specific fluids with which the component may come into contact during its service life. (Note: For fluid immersion testing of optical fiber, refer to FOTP-74¹). <br>The primary tests defined herein are for accelerated aging and continuous immersion evaluation by complete immersion of samples for specified times at specified temperatures. A secondary method is defined only for non-Military cables and defines proximity or periodic exposure. This test is a "wet patch" test and is only used if specified by the Detail Specification. <br><strong>Failure modes</strong> <br>Potential failure modes for this test include, but are not limited to: <br>Swelling of any materials. (Exception &#8211; materials that are functionally designed to swell, e.g., swellable water blocking tapes.) <br>Dimensional changes other than swelling. <br>Softening of any materials. <br>Loss of seal or adhesive bonding between two bonded surfaces. <br>Discoloration of materials, finishes, and marking (may or may not be considered detrimental). <br>Changes in mating and/or coupling characteristics. <br>Corrosion of any materials, finish peeling, cracking, or flaking. <br>Inability to mate or unmate (connector, device, or cable assembly). <br>Degradation of cable/connector optical transmission characteristics. <br>¹ FOTP-74 supersedes FOTP-75, <em>Fluid Immersion Test for Optical Waveguide Fibers</em>.
