Japanese Industrial Standards
The Japanese Industrial Standards ( JIS, Japanese日本 工业 规格, Nihon Kikaku Kōgyō ) determine the standards that are used in Japan for industrial activities. The standardization process is coordinated by Japanese Industrial Standards Committee and published the standards by the Japanese Standards Association.
In the Meiji period private companies were responsible for the definition of standards. On the part of government standards and specifications have been mainly used in the procurement of certain products such as armaments.
These standards were first summarized in 1921 ( the old JES ) to an official standard. During the Second World War, these standards have been simplified in order to meet the increased demand.
The current Japanese Standards Association was founded in 1945 after the defeat of Japan and a year later the new rules of the Japanese Industrial Standards Committee were announced.
The legal basis for today's current Japanese Industrial Standards ( JIS) is the law on industrial standardization (Industrial Standardization Law ), which was enacted in 1949.
Together with the 2004 revised version of the latter was also the JIS character, which is used for certification of products, as amended. The new logo has been used since October 1, 2005 and is said to have replaced the old one until 1 October 2008. The old JIS character may be used only within the transitional period until 30 September 2008. Producers receive at an approved new application for certification or in the extension of an old certification permission to use the new character.
