MIL-STD-681F
5.7.2.2 Stripe or band spacing. On single stripe or band coloring, the spacing between each stripe or band shall be not less than twice the width of the individual stripe or band. On multiple stripe or band coloring, the spacing between stripes or bands within a grouping shall be not less than the width of the narrow stripe or band.
5.7.2.3 Length of lay (spacing between groups). The spacing between groups of bands shall be at regular intervals along the wire. The spacing separating a group of bands from the next grouping shall be greater than the spacing between the bands within a group, but shall not exceed 3 inches.
NOTE: Length of lay is defined as the longitudinal distance along the wire from the starting point of one grouping of stripes to the starting point of the next repetition of the grouping. Also, length of lay required does not apply if stripes of colored insulation material are used.
5.7.2.4 Spacing between groups of bands. The spacing between groups of bands shall be at regular intervals along the wire. The spacing separating a group of bands from the next grouping shall be greater than the spacing between the bands within a group, but shall not exceed 3 inches.
5.8 Braided wire covering. When the wire covering includes a braided covering (of synthetic yarn or continuous filament glass yarn) over the insulation, with systems I and II color coding, the braided covering shall be the same base color; with systems III, IV, and VI color coding, the insulation and braided coverings shall be natural white. If color coded striping or banding is required on braided covering of systems I, II or IV color coded wires, the method described in 5.5 shall be adopted. If color coded banding is required on braided covering of system VI color coded wires, the method described in 5.6 shall be adopted. When helical stripes are used, colored carriers of suitable widths shall be used to form the coding stripes. The narrow (second and third) stripe, when applicable, shall be formed by using colored yarn in one carrier. The spacing between stripes in any group shall be formed by one base color carrier. The colored helical stripe, striping sequence, and length of lay shall be in accordance with 5.7.1, 5.7.2,
5.7.2.1, 5.7.2.2, and 5.7.2.3.
