to evaluate how components resist road salt and atmospheric pollutants. Dust & Radiation : Provides guidelines for protecting equipment against dust ingress solar radiation Evolution of the Standard

The standard is strict about contamination. It details how to extract a sample from the radiator or overflow tank without introducing air bubbles or debris, which would alter the test results.

JASO D 0144 establishes a standardized method for testing the durability and reliability of automotive electrical and electronic devices when exposed to sustained high temperatures and high humidity.

To align local methodologies with international benchmarks, the JSAE developed the series as a direct harmonized equivalent to the international ISO 16750 standard. Specifically, JASO D014-4 aligns with ISO 16750-4 , focusing entirely on climatic stresses.

Components under this specification undergo rigorous simulations inside environmental test chambers. The primary climatic stresses evaluated include: Constant High and Low-Temperature Tests to evaluate how components resist road salt and

Simulate specialized environments, such as engine compartments, passenger cabins, or exterior mounting. JASO D014-4 vs. ISO 16750-4

Different levels of testing based on where the component is located in the car (e.g., engine compartment vs. passenger cabin).

. Directly equivalent to the international ISO 16750-4 standard, a JASO D0144 PDF acts as the fundamental blueprints used by engineers worldwide to ensure that electronic components—ranging from basic sensors to advanced electric vehicle (EV) control units—survive harsh environmental exposures such as thermal shock, extreme humidity, and intense solar radiation.

To prevent short circuits, voltage drops, and thermal runaway, the standard mandates:
