Cable Testing Standards IS-7098-1985

The document outlines various types of tests performed on cables according to IS – 7098 (Part 2) - 1985, including type tests, acceptance tests, and routine tests. Type tests extensively evaluate the conductor, insulation, outer sheath, and overall cable design. Acceptance tests examine critical characteristics. Routine tests check resistance, insulation, and voltage withstand. Optional tests also exist, such as cold impact tests on the outer sheath.
