Anotace

This specification covers ozone-resistant thermoplastic elastomer insulation for electrical wires and cables operating continuously at specified conductor temperatures, within the specified voltage range, and under wet or dry conditions. The prescribed tests cannot be performed unless the insulation is formed around a conductor, but these are done solely to determine the insulation properties and not to test the conductor or completed cable. Each test sample should be subjected to ac and dc voltage withstand tests as well as insulation resistance tests and should comply with the required values for aging, heat distortion, electrical permittivity, increase in capacitance, stability factor, and accelerated water absorption.
