-up to 80 mm (3.1496 in.) in case of screening continuity rework
having to be stepped because of space requirements aft of the
equipment receiving the wiring.
Tools such as scalpels or scissors are necessary.
For the step 3 :
The stripping length depends on the length required to connect the
wire conductor to the end component and also depends on the
dimensions of the end component barrel plus the tolerances of the
stripped cable aft of the barrel.
This length "A" is given in the topic relevant to the use of each end
component.
The tools necessary to strip depend on the gauge of the wire to be
stripped.

C. Stripping procedure for each applicable tool :
R R _______CAUTION : MAKE SURE THAT YOU DO NOT CUT THE BRAIDED SHIELD OR CAUSE DAMAGE TO THE CENTER CONDUCTOR WHEN YOU STRIP THE CABLE.
R
R R _______CAUTION : DO NOT USE TOOLS THAT HAVE V-SHAPED OR SHEAR-TYPE KNIVES. THIS TYPE OF KNIFE CAN CAUSE DAMAGE TO CABLES.
R
(1) Scalpels, cutter, cable knife or Equivalent :
R R _______WARNING : BE VERY CAREFUL WHEN YOU USE THESE TOOLS. THEY ARE SHARP AND CAN CUT YOU.
R
____NOTE : During the stripping operation, to obtain a good stripping quality, the cable must be held at right angles to the blades and the insulation must be removed parallel to the cable axis.
(a) Conditions of application Manual insulation stripping with cutting tools is allowed for : - cables of cross section above 5 mm2 or wire gauge 10, - fire resistant cable insulation, - screened cables (braided screening or helical screening), - coaxial cables.
(b) Insulation stripping Procedure (Ref. Fig. 002) - The end of the cable must have a clean cut. - Determine the location where the insulation must be cut, using a scalpel, without pressing, make a circular notch on the cable insulation to start cutting the insulation. - Fold the cable on the notch to break the insulation. - By hand or using a sticky paper or an appropriate tool not to damage the conductor, pinch the cable end on the insulation and remove it.
(c) Screening stripping procedure (Ref. Fig. 003, 004) Depending on the screening type of the cable and/or the type of screening pick-up to be made, several methods of screened stripping are possible.

Cutting flush the insulator, method :
-Using scissors, cut the screening flush with the insulator, bring back the strands in the cable direction.
-Depending on the type of cable, slide a heat-shrinkable sleeve or a crimp-on the sleeve specified in the wiring documents over the shielding end.
Window type stripping method :
Only solder sleeves are to be fitted to this type of
stripping.
This stripping method allows the screening pick-up to be
stepped more easily in the case of a high number of screened
cables :
Cutting method :
-
Make 3 circular notches over a length "L" with respect to the sleeves used.
-
Make a longitudinal notch and remove the pieces of insulation.
-The solder sleeve will be moved and positioned on the screening.
Sliding method :
-Make a circular notch.
-Slide the insulation on the screening over a length "L" and leave it in position.
-This length "L" depends on the length of the solder sleeve used.
-The solder sleeve will be moved and positioned on the screening.
Wrapping and cutting method :
Mechanical ferrules or solder sleeves can be equally fitted to
a stripped tubing on a cable end.
-After the insulation over a length "L" has been stripped.
L : length necessary, as short as possible but sufficient, for
further work (pinning, unpinning, repairs, etc...).
-Unwind the braided screening and cut at the length "L1" or
wind the helical screening over the length "B".
L1/L2 : length with respect to the type of end component
