scope:

This Standards publication covers specific requirements for FEP (Fluorinated Ethylene Propylene) insulated solid and stranded wire, designed for the internal wiring of high reliability electrical and electronic equipment. This Standards publication addresses 250 volt (type KT), 600 volt (type K), and 1000 volt (type KK) wire and permits continuous conductor temperature ratings of −65°C to +200°C with silver-coated or nickel-coated conductors and −65°C to +150°C with tin-coated conductors. These types of hook-up wire are used when the following requirements are called for:

a. high-temperature resistance;

b. low-temperature resistance;

c. low dielectric constant;

d. resistance to cleaning solutions or a variety of chemicals that may come in contact with either the wire or the equipment; and,

e. good flexibility and flex life when stranded conductors are used.
