3.7.2.1 Method 1. Identification Method 1 shall be surface printing of both number and color designations.
The legend shall be printed in contrasting color: preferably white ink on black or dark background or black ink on
white or light background. The legend shall be repeated at intervals not exceeding 3 inches and alternate legends
. Unless otherwise specified
shall be inverted. For example, 10 ORANGE BLACK
(see 3.1), the axis of the characters shall be perpendicular to the longitudinal axis of the wire. The character type
shall be block and shall have a height in accordance with the diameter over which it is applied in accordance with
table VI.

3.7.2.2 Method 2. Identification Method 2 shall use translucent (opaque) polyester tapes (see 3.3.6) which
have been printed with both the number and the color designation. The legend shall be printed with black ink and
shall be repeated at intervals not exceeding 3 inches and alternate legends shall be inverted. The character type shall
be block and shall be approximately 3/32 inch in height.
3.7.2.3 Method 3. Identification Method 3 shall be the use of solid base colors or solid base colors with tracers
as required. The base color may be either the color of the insulation or the color of a coating applied to the
insulation. The tracers shall be approximately 1/32 inch wide ink stripes of the required color applied helically with
1 ½±¼ inch lay. If two tracers are required, the second shall be half the width of the first.
3.7.2.4 Method 6. Identification Method 6 shall consist of numerals printed in ink on the conductor insulation.
For conductors having a jacket directly over the insulation, the numerals may be printed in ink on the jacket, at the
manufacturer's option. White ink shall be used for a red or black background; black ink shall be used for a white
background. Numerals may be perpendicular or parallel to the longitudinal axis of the conductor (see figure 1).
Numeral width shall be proportional to conductor outside diameter (O.D.) range as shown in Method 1 (see 3.7.2.1).
Numeral height shall be 2½ to 3 times numeral width. Each numeric legend shall be underlined. Two digit legends
which are parallel to the longitudinal axis shall have the bottom numeral underlined. Legends shall be alternately
inverted and shall be repeated at intervals not greater than 1½ inches.
3.7.3 Manufacturer's identification tape. Unless otherwise indicated on the specification sheet, all cables with
a core diameter of 0.250 inch or greater shall contain continuous, thin, moisture resistant marker tape, not less than
1
/10 inch wide. Cables with core diameters less than 0.250 inch shall either contain a manufacturer's identification
tape, or a marker thread in accordance with 3.7.3.1. The marker tape or threads shall be placed directly under the
cable binder tape or jacket. The tape shall be printed to show the following information at intervals not greater than
1 foot.
