The industrial standards published by Japan fluid Power Association (JFPA) covers technical matters common to the fluid power industry, but not stipulated in the JIS standards. The Industrial Standards Study Working Group under the Standardization Committee of JFPA conducts study for standardizing on specific technical matters raised as candidate items for JFPA standards. Listed below are those authorized and published so far by JFPA through the mentioned proceedings. (Copies, though in Japanese, are available upon request).
