MIL-DTL-22759/80A
Solderability: Not required. This slash sheet is primarily intended for crimp terminations. For solderability
applications use the silver coated copper version of this specification.
Strippability: (Group II quality conformance test). Test size 26 - 14 wire only in accordance with ASTM D 3032
section 27. The length of the insulation slugs shall be 0.25 inches. Strip forces shall be as follows. No evidence of
insulation shall be left on the conductor when viewed with the naked eye.

Tape Overlap: In accordance with MIL-STD-2223, method 6005
Tensile Modulus: Test composite film in accordance with ASTM D 882, method A
Thermal index: 150°C (302°F) minimum for 10,000 hours (Test required for initial qualification only). Test
size 20 only in accordance with ASTM D 3032, Section 14.
Thermal shock resistance: Oven temperature, 200°C ± 2°C (392°F ± 3.6°F), Maximum change in measurement ,
0.091 inches. No cracking.
UV Laser Marking: (Test required for initial qualification only) FP materials shall be formulated in such a manner
to achieve a 62 % minimum contrast level when marked by an Ultraviolet (UV) laser source operating at a
delivered power not to exceed 1.5 Joules/cm2. The contrast level is defined as:
CL = (Reflectance of the background insulation - Reflectance of the laser mark) x 100
Reflectance of the background insulation
Wrap (mandrel wrap): No cracking, no dielectric breakdown. Use mandrels specified in Table VI. Dielectric test,
2500 volts (rms), 60 Hz.
