SAE J1455 Recommended Environmental Applications Test for Electronic Equipment Design in Heavy Duty Vehicle Applications

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of SAE J1455 testing. The SAE J1455 standard is a set of tests recommended for the automotive industry that characterizes the environmental performance and reliability requirements of electronic equipment designed for heavy-duty road and off-road vehicles.

SAE J1455 is one of the most common testing standards for the automotive market and is considered essential for testing both road and off-road vehicles as well as heavy trucks. The scope of SAE J1455 testing covers all suitable stationary applications using components derived from this vehicle, as well as environments that affect the performance and reliability of electronic equipment designed for heavy-duty land and off-road vehicles. A few examples of such vehicles are road trucks, trailers, buses, construction machinery and agricultural implements including implements.

Components in tests performed according to SAE J1455 standards; Various results are obtained by exposure to factors such as temperature, humidity, salt spray atmosphere, immersion and splash (Water, Chemicals and Oils), steam cleaning and pressure washing, mushroom, dust, sand and gravel bombardment, altitude, mechanical vibration, mechanical shock. Most of the environmental conditions specified in SAE J1455 are simulated to real-world conditions. Often, combined exposure can have more serious consequences than exposing the part to one condition at the same time.

For example, with regard to temperature and vibration, it can be concluded whether the design of the products and the installation site will be exposed to both temperature and vibration at the same time. Another example is humidity can be very important as it relates to the sealing integrity of the electrical components tested under exposure to both high and low temperatures. Water droplets from moisture will condense at high temperatures, possibly penetrating the seals. At low temperatures, the water inside the component may freeze if the seal fails.

In general, SAE recommends that the toughest environmental tests (eg, shock and vibration) be run last. Temperature cycling is usually performed first to condition the test object to operate mechanically.
