3 Terms and definitions

The terms and definitions defined by IEC 61196-1 apply to this document.

4 Overview

Plastics show different characteristics when they come into contact with solvents and contaminated liquids, even if these solvents and contaminated liquids have similar components.

Belong to the same category.

Therefore, the cable is usually not considered to be resistant to solvents or contaminated liquids. It can only be regarded as resistant to such solvents or contaminated liquids after passing the test.
