Description

Intent

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).

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.

Failure modes

Potential failure modes for this test include, but are not
limited to:

Swelling of any materials. (Exception – materials that are
functionally designed to swell, e.g., swellable water blocking
tapes.)

Dimensional changes other than swelling.

Softening of any materials.

Loss of seal or adhesive bonding between two bonded
surfaces.

Discoloration of materials, finishes, and marking (may or may
not be considered detrimental).

Changes in mating and/or coupling characteristics.

Corrosion of any materials, finish peeling, cracking, or
flaking.

Inability to mate or unmate (connector, device, or cable
assembly).

Degradation of cable/connector optical transmission
characteristics.
