What is BS EN ISO 6722-10:2018?

BS EN ISO 6722-10:2018 is a technical standard that specifies the requirements for single-core cables used in road vehicles. This standard provides guidelines for the construction, performance, and testing of cables that are used in the electrical systems of vehicles such as cars, trucks, motorcycles, and agricultural machinery.

Cable Construction

The construction of cables specified in BS EN ISO 6722-10:2018 comprises several layers, each with specific functions. The innermost layer, known as the conductor, carries electrical current. It is generally made of copper or aluminum due to their excellent electrical conductivity. The conductor is surrounded by an insulation layer made of materials like PVC, XLPE, or TPE, which provide electrical insulation and protection against environmental factors such as moisture, heat, and chemicals.

Performance Requirements

BS EN ISO 6722-10:2018 sets out various performance requirements for cables used in road vehicles. These include electrical properties, such as maximum voltage rating and resistance to electrical stress, as well as mechanical properties like flexibility and resistance to cut-through and abrasion. Additionally, the standard specifies flame propagation characteristics to ensure safety in case of fire. Cables meeting these requirements help to ensure reliable and safe operation of the electrical systems in vehicles.

Testing and Compliance

To determine compliance with BS EN ISO 6722-10:2018, cable manufacturers perform various tests on their products. These tests may include measurement of conductor diameter, thickness of insulation, and verification of electrical properties. Mechanical tests, such as flexibility and resistance to cut-through, are also conducted. Additionally, the standard requires cables to undergo flame propagation testing according to specific criteria. Compliance with these tests allows cables to be certified and labeled accordingly.
