Simulates abrupt exposure, such as an engine part getting splashed with freezing slush or rainwater while operating hot. Damp Heat & Humidity Cycles
: The standard uses codes to define the severity of the environment. You must match your component's intended use to the correct "Z" profile. Perform Sequential Testing
: In 2006, JSAE introduced the JASO D014 series to harmonize with the ISO 16750 series. The Abolishment : JASO D001 was formally withdrawn in 2021.
is a Japanese automotive standard specifically focused on the testing methods for electrical and electronic equipment used in road vehicles. It is part of a broader series (JASO D014) that defines environmental conditions and testing procedures to ensure automotive components can withstand the rigors of vehicle operation. Overview of JASO D014-4 jaso d0144 pdf
The JASO D0144 standard is significant for several reasons:
If you are looking at a PDF of the standard, you will likely find the following structured sections:
However, you can legally access the official PDF through several authorized channels: Simulates abrupt exposure, such as an engine part
This series, published in 2014, is the current version and is actively used in the industry.
JASO D0144 is a technical standard published by the Society of Automotive Engineers of Japan (JSAE). It defines the general requirements, test methods, and performance criteria for multi-pole connectors used in electronic wiring harnesses for automobiles.
The standard, established by the Japanese Automotive Standards Organization (JASO) , serves as one of the most critical engineering benchmarks for validating the environmental resilience of automotive electrical and electronic components. Specifically, JASO D014-4 focuses on climatic loads , outlining the precise test methods and requirements needed to ensure electronic components can survive extreme temperatures, moisture, and chemical exposure over a vehicle's lifecycle. Perform Sequential Testing : In 2006, JSAE introduced
The establishes standards to ensure high-quality components for vehicles, particularly for Japanese manufacturers. JASO D014-4 is titled "Automotive parts - Environmental conditions and tests for electrical and electronic equipment - Part 4: Climatic Loads." Key Features of JASO D014-4:
: Uses "thermal shock" to simulate extreme transitions, testing for mechanical cracks or sealing failures due to differing thermal expansion rates. Water & Moisture Resistance : Includes splash water tests
: Tests resistance to moisture and condensation.
Subjecting parts to high humidity, including damp heat, steady-state, and cyclic tests.
