No, it is copyrighted intellectual property. However, many wire manufacturers publish "cross-reference guides" that summarize the key data for free.
JASO standards are copyrighted and sold by the Society of Automotive Engineers of Japan (JSAE) or authorized distributors. They are not freely distributed like academic papers.
Large automotive parts manufacturers (Sumitomo, Yazaki, Furukawa) often publish summarized versions or cross-reference tables. While they will not give you the full copyrighted PDF, their public technical data sheets often replicate the critical tables.
JASO D0144 does not exist in isolation. It often references or aligns with broader Japanese Industrial Standards (JIS), specifically:
However, JASO D0144 tailors these general engineering rules specifically for automotive applications, addressing unique requirements found in vehicle manufacturing that general mechanical standards might not cover in detail.
If you want, I can:
The JASO D0144 standard could potentially relate to the performance of lubricants, specifically for automotive applications. Here are some general features and purposes that might align with what you're looking for:
If you suspect counterfeit wire, use the PDF's test methods:
Let’s say you are a fleet manager. You pull a coolant sample from a 2021 truck. Using a generic tester, the freezing point reads -35°C. Using the JASO D0144 method, you perform a titration and discover the reserve alkalinity has dropped to 1.0 (when the threshold is 3.0).
The JASO D0144 standard would tell you:
This saves the engine from internal pitting and cavitation erosion over the next winter.
