ISO 6722

ISO 6722 is an international standard developed by the International Organization for Standardization (ISO) that defines requirements for single-core low-voltage cables in automotive electrical systems, mainly for 12V and 24V vehicles. It provides global benchmarks for safety, durability, and performance.

The standard covers copper or tinned copper conductors rated up to 60V DC, with temperature classes from -40°C to +150°C. It allows various insulation materials such as PVC, XLPE, TPE, and ETFE to suit different automotive applications.

ISO 6722 specifies key criteria for wire construction, insulation quality, and electrical reliability, including resistance to heat, abrasion, and aging. Widely adopted by OEMs and harness manufacturers, it underpins common wire types like FLRY, AVSS, and TXL, ensuring dependable use in engine compartments, vehicle bodies, and interior electronics.
