Japan Industrial Standard
|Old JIS symbol|
The Japanese Industrial Standards ( JIS , Japanese 日本 産業 規格 , Nihon Sangyō Kikaku ) determine the standards that are used in Japan for industrial activities. The standardization process is coordinated by the Japanese Industrial Standards Committee and the standards are published by the Japanese Standards Association .
In the Meiji period , private companies were responsible for setting standards. On the government side, standards and specifications were mainly used in procurement for certain goods such as armaments.
These standards were first merged into one official standard (the old JES) in 1921. During the Second World War , these standards were simplified to meet the increased demand.
The current Japanese Standards Association was formed in 1945 after the defeat of Japan, and a year later the new regulations of the Japanese Industrial Standards Committee were promulgated.
The legal basis for today's Japanese Industrial Standards (JIS) is the Industrial Standardization Law, enacted in 1949.
Together with the revised version of this law in 2004, the JIS mark, which is used to certify products, was also changed. The new symbol has been in use since October 1, 2005 and is supposed to have replaced the old one by October 1, 2008. The old JIS mark may only be used during the transition period until September 30, 2008. Manufacturers receive permission to use the new symbol when a new certification application is approved or when an old certification is renewed.
Classification and numbering
The names of the standards follow the form “JIS A bbbb: yyyy”. Here is A for a letter that specifies the area of standards (see list), followed by four (or five in some standards, the ISO norms correspond) digits and the year of publication.
The different areas of JIS are:
- A - Civil engineering and architecture
- B - mechanical engineering
- C - electronics and electrical engineering
- D - automobile manufacturing
- E - railway construction
- F - shipbuilding
- G - Ferrous materials and metallurgy
- H - Non-ferrous materials and metallurgy
- K - chemical engineering
- L - textiles
- M - mining
- P - paper and pulp
- Q - management system
- R - ceramic
- S - domestic goods
- T - Medical equipment and safety devices
- W - aeronautical engineering
- X - information processing
