6. NOTES
(This section contains information of a general or explanatory nature that may be helpful,
but is not mandatory.)
6.1 Intended use. The wire strand covered by this specification is intended for use in
aircraft control systems applications where high resistance is needed against corrosion and
abrasion. Wire strand to this specification should not be used for applications subject to bending
fatigue.
6.2 Acquisition requirements. Acquisition documents should specify the following:
a. Title, number, and date of this specification.
b. Type, class, construction, composition, nominal diameter, and length of wire strand
(see 1.2).
c. Packaging requirements (see 5.1).
6.3 Qualification. With respect to products requiring qualification, awards will be made
only for products that are, at the time of award of contract, qualified for inclusion in QPL-87161
whether or not such products have actually been so listed by that date. The attention of
contractors is called to these requirements, and manufacturers are urged to arrange to have the
products that they propose to offer to the Federal Government tested for qualification in order
that they may be eligible to be awarded contracts or orders for the products covered by this
specification. Information pertaining to qualification of products may be obtained from Defense
Supply Center Richmond, ATTN: DSCR-VEB, 8000 Jefferson Davis Highway, Richmond, VA

6.4 Definitions.
6.4.1 Center wire. The center of all strand is an individual wire and is designated as a
center wire.
6.4.2 Diameter. The diameter of wire strand is the diameter of the circumscribing circle,
or the distance across opposite wires.
6.4.3 Lay (or twist). The helical form taken by the wires in the strand and by the strand
in the wire rope is characterized as the lay (or twist) of the strands or wire rope, respectively. In
a right-hand lay, the wires of the strand are the same direction as the thread on a right-hand
screw, and for a left-hand lay the strands of wires lay in opposite direction.
6.4.4 Length of lay (or pitch). The distance parallel to the axis of the strand, in which a
wire makes one complete turn about the axis, is designated as the length of lay (or pitch) of the
strand.
6.4.5 Master reel. The master reel is the large manufacturing reel that is used to hold the
wire strand as it is continuously manufactured.
