3.7.5.1.2 White polyamide braid and polyamide finishers. Jackets shall be constructed with white polyamide fibers, 210 denier,
woven in such a manner as to provide complete coverage, when viewed with the unaided eye, and shall be impregnated with a clear
polyamide finisher.
3.7.5.1.3 Polyester fiber braid with high temperature finishers. Braided polyester fiber jackets shall be constructed with the fiber
woven in such a manner as to provide complete coverage, when viewed with the unaided eye, and shall be impregnated with a high
temperature finisher. The color of the finished braids shall be white or tan. After subjection to the heat aging test, the finisher shall
show no indications of decomposition.
3.7.5.1.4 Extruded or taped polytetrafluoroethylene. Concentrically extruded or taped polytetrafluoroethylene jackets shall have
a wall thickness in accordance with table V (see 4.3.13). If polytetrafluoroethylene tapes are used, they shall be unsupported and
shall be a minimum of two contrahelically wrapped tapes each applied with a 25 percent minimum overlap. The tapes shall
subsequently be heat sealed, and shall meet the requirements of 4.3.17.1. The polytetrafluoroethylene jackets shall be white.
3.7.5.1.5 Extruded white polyvinyl chloride. Extruded polyvinyl chloride jackets shall be colored white and shall have wall
thickness in accordance with table V (see 4.3.13). The tensile strength and elongation of the jacket shall be 2000 lbf/in2 minimum
and 150 percent minimum, respectively, and shall be tested in accordance with 4.3.13.1. Polyvinyl chloride shall not be used for
aerospace purposes.
3.7.5.1.6 Extruded fluorinated ethylene propylene. Jackets shall be constructed of a clear or white fluorinated ethylene
propylene as indicated by the style and shall be concentrically extruded with a thickness in accordance with table V. The tensile
strength and elongation of the jacket shall be 3000 lbf/in2 minimum and 200 percent minimum, respectively, and shall be tested in
accordance with 4.3.13.1.
3.7.5.1.7 Glass braid with polytetrafluoroethylene finishers. Braided polytetrafluoroethylene coated glass fiber jackets shall be
constructed with treated glass fiber containing not less than 15 percent by weight of polytetrafluoroethylene and woven in a manner
that will provide complete coverage. The braid shall be impregnated and coated with a polytetrafluoroethylene finisher.
3.7.5.1.8 Extruded crosslinked polyvinylidene fluoride. Jackets of extruded and crosslinked polyvinylidene fluoride shall be in
accordance with table V. The tensile strength and elongation of the jacket shall be 4000 lbf/in2 minimum and 200 percent minimum,
respectively, and shall be tested in accordance with 4.3.13.1.
3.7.5.1.9 Polyvinylidene fluoride. These jackets shall be extruded of clear polyvinylidene fluoride. The tensile strength and
elongation of the jacket shall be 5000 lbf/in2 minimum and 225 percent minimum, respectively, and shall be tested in accordance
with 4.3.13.1.
3.7.5.1.10 Taped polyimide/fluorinated ethylene propylene. The jackets of polyimide/fluorinated ethylene propylene tapes shall
consist of two or more tapes. The inner tape shall be a one-side polyimide/fluoropolymer coated tape applied with not less than 20
percent overlap and with the polyimide side facing the shield or component wires. Succeeding tapes shall be applied in alternating
directions and with not less than 30 percent overlap. The tapes shall be thermally sealed together to provide a jacket with a wall
thickness in accordance with table V.
3.7.5.1.11 Ethylene-tetrafluoroethylene copolymer. These jackets shall be extruded ethylene-tetrafluoroethylene copolymer and
shall have a wall thickness as shown in table V. The tensile strength and elongation of the jacket shall be 5000 lbf/in2 minimum and
150 percent minimum, respectively, and shall be tested in accordance with 4.3.13.1.
3.7.5.1.12 Ethylene chlorotrifluoroethylene copolymer. (Inactive for new design). Jackets of ethylene chlorotrifluoroethylene
copolymer shall have a wall thickness as shown in table V. The tensile strength and elongation of the jacket shall be 5000 lbf/in2
minimum and 150 percent minimum, respectively, and shall be tested in accordance with 4.3.13.1.
