ISO 16750-4 Electrical Loads Durability Testing in Road Vehicles

The ISO 16750 series of standards provides a framework for ensuring that automotive components can withstand the harsh environmental and operational conditions they will encounter during their lifecycle. Specifically, ISO 16750-4:2013 Electrical Loads Durability Testing in Road Vehicles is designed to evaluate how well electrical systems within vehicles endure extreme temperature variations, moisture exposure, and other environmental stresses over time.

This standard applies primarily to battery packs, power electronics, lighting assemblies, and any other component that relies on reliable electrical performance. Compliance with ISO 16750-4 ensures that the tested components can withstand these conditions without failure or degradation of performance parameters such as current flow, voltage stability, and resistance.

The testing protocol involves subjecting the component to a range of temperatures (from -40°C to +85°C), humidity levels up to 93% relative humidity, and various environmental stresses including vibration, altitude changes, and salt fog exposure. This comprehensive approach simulates real-world conditions that automotive components face during manufacturing, transport, and use.

During the test, a series of electrical loads are applied to simulate the expected current draw and power consumption under different operating conditions. These conditions can include starting the vehicle's engine, running auxiliary systems like air conditioning and heating, as well as driving at various speeds on diverse road surfaces.

The testing process typically spans several weeks or months, depending on the specific requirements of the component being evaluated. Throughout this period, engineers monitor critical performance indicators such as temperature rise, power consumption, and resistance levels to ensure that the tested components remain within acceptable operational limits throughout all environmental stress conditions.

Once completed successfully, compliance with ISO 16750-4 indicates that the component has demonstrated durability under severe environmental conditions. This certification is particularly valuable for manufacturers looking to enhance their products' reliability and market competitiveness by meeting stringent global quality standards.
