Field Test Resistance

(see Figure 1 below)

10,000 ohms

Scotch® Electrical Semi-Conducting Tape 13 can be checked for resistance with an

ohmmeter. After elongating the tape 25% of its original width, probe points placed one

inch apart on tape should measure 10,000 ohms or less. Figure 1 illustrates the type

of results which may be expected in the field.

Effects of Scotch® Electrical Semi-Conducting Tape 13 on resistivity of semi-

conductive cable shield.

The Insulated Conductor Committee (ICC) has set a standard for compatibility of

materials placed on shielded cables. When tested according to ICC Guide P1026,

products in contact shield shall have a resistance measurement below ten ohm-

meters. Scotch® Electrical Semi-Conducting Tape 13 complies with requirements of

ICC Guide P1026.

Resistivity of cable semi-conductive shield overwrapped with Scotch® Electrical

Semi-Conducting Tape 13 remained the same as, or lower than, that of the exposed

shield (control). This test shows Scotch® Electrical Semi-Conducting Tape 13 does

not significantly affect semi-conductive cable shields.
