This International Standard specifies test methods and requirements for basic and high-performance round, screened and unscreened, multi-core sheathed cables, intended for use in road vehicle applications. The unscreened, single-core cables must be in accordance with ISO 6722. Other cores may be used but, in these cases, the construction and tests required to ensure functionality of these cores must be agreed between the customer and supplier. See ISO 6722 for temperature classes.
