The importance of reliable automotive cables
Properly functioning cables play a critical role in the safe, reliable operation of automobiles. Cable malfunctions can lead to short circuits in power cables, high latency in self-driving vehicle cameras and other safety hazards that may result in accidents and injuries. Enlisting UL Solutions to evaluate your cables in accordance with relevant industry specifications can help mitigate these safety risks.
Automotive cables must perform correctly without failure, even under severe exposure conditions, regardless of construction. Automotive cables must therefore meet stringent technical requirements to resist the extreme environmental conditions road vehicles encounter. UL Solutions offers testing services for various types of automotive cables used in the industry over a wide range of extreme temperatures (typically -40°C to 125°C or higher, up to 250°C).
In addition to thermal properties, UL Solutions can perform tests associated with environmental, flame propagation, mechanical, chemical resistance and electrical aspects. Our services cover wiring in electrical and electronic systems and power and high-speed data interconnections to help you compete in the global market. We can also support the required electrical transmission (signal integrity) performance testing for automotive data cables.
Automotive cable standards and specifications
UL Solutions can evaluate automotive cables per a number of industry standards and specifications. Expert testing can help confirm and verify product compliance with global or industry requirements, which can help reduce noncompliance risk throughout your supply chain.
