According to Japanese Industrial Standardization Law regulations , JIS standard object division drugs 、 pesticides 、 Chemical fertilizer , silk food And other agricultural and forestry products have special standards or technical specifications In addition, it also involves various Industry Domain. Its contents include: Product standard （ product Shape, size quality , performance, etc.) Method standard (Test, analysis, detection and measurement methods and operating standards, etc.) Basic standards (Terms, symbols Company , priority number, etc.). Major includes: Architecture , machinery electrical 、 metallurgy 、 transport 、 chemical industry , mining spin , paper making, medical equipment, ceramics and Daily Necessities 、 information technology Etc. Since 1990, the total number of JIS standards has remained around 8200. Including: Product standard About 4000, Method standard 1600, 2800 basic standards. As of the end of March 2006, share There are 9728 current JIS standards. It is divided into civil construction, general machinery, electronic instruments and electrical machinery automobile 、 Railway 、 a ship 、 steel 、 Nonferrous metal , chemistry, fiber, mining, pulp and paper management system , ceramics, daily necessities Medical safety Appliances, aviation information technology 19 others. As of February 7, 2007, there were 10124 current JIS standards. According to the Japanese Industrial Standardization Law, Japan has implemented the quality mark since July 1949 system 。 Initially only product Is an object. In March 1950, a total of 10 products, such as cement tile and pig iron, obtained the first batch JIS mark 。 In 1966 machining Technology formally incorporated JIS mark System. In January 1967, "industrial chrome plating" was approved as the first JIS designated processing technology project 。 Since then machining technology JIS logo. By the end of March 1998, there were more than 1000 varieties of products designated by the JIS mark, and more than 10 kinds of designated processing projects; More than 12000 domestic and foreign manufacturers have obtained more than 16000 JIS marks licence 。 JIS standard The development process has Standardization And maintain transparency. From project Establishment Draft Standards The formulation, standard review and other processes of are officially announced in the official standardization magazine, so that any interested person with opinions can have the opportunity to put forward their own opinions. At present, JIS has a total of more than 8000 standards, including more than 320 steel standards. The characteristics of JIS steel standards are that except for mechanical structural steel, "steel" and "steel products" in the standards are unified, and the use characteristics are relatively prominent, which is more convenient in use. There is no complicated situation of standard reference except for test methods and standards. At the same time, standard index Compare the thick lines, and the same standard can provide manufacturer stay production The product has a large degree of freedom. Japan participated in ISO in 1952 and in 1953 IEC , in order to achieve WTO/TBT Agreement ( World Trade Organization Japan actively participated in ISO Standards Development work of and multiple technologies committee And formulated the "JIS and ISO The three-year plan of "integration" has been attached to several JIS standards ISO Standards And try to be close to each other. In addition to developing JIS standards“ JIS mark "System" is another pillar of Japan's industrial standardization system. JIS mark system is an official certification system, which is mainly based on product Manufacturer and product Review itself to determine whether the product actually conforms to relevant JIS standard stipulates that the product shall be identified, so as to reassure the buyer of the product and improve the quality of the product way Yes: ① The ministers in charge shall designate the product standards suitable for the implementation of JIS marking system in their own departments, which shall be announced in official newspapers.
② Where JIS mark Specify the product's manufacturer Processing factory can apply and fill in regulations Of application , to the main product's executive director The minister applied. ③ The competent minister applies to factory Designate an inspection officer to manufacture equipment, inspect equipment Quality Assurance And review the product itself Overall inspection To judge the factory Whether there are products that meet JIS standards and can continue to manufacture production Of ability , after confirming the capacity of the factory executive director The minister issued a certificate allowing the factory to mark the JIS mark on the products they produced. This certification system has been open to products manufactured in accordance with JIS standards abroad since 1980. The foreign manufacturers apply to the competent ministers of Japan, and those confirmed after examination will be recognized, and the competent ministers will issue certificates. So far, more than 300 foreign manufacturers have won JIS Certificate 。 Corresponding to Japanese Industrial Standard (JIS) code : A - Civil and architectural; B - General machinery; C Electrical and electronic; D- automobile ； E-railway; F- a ship ； G-steel; H - Non ferrous metal; K-chemistry; L-fiber; M-mine; P-pulp, paper; Q-management system; R-furnace industry; S-daily necessities; T - Medical safety equipment; W-Aviation; X- information processing ； Z-Other. IS standards are classified according to their standard objects. At present, there are "civil construction", "automobile"“ steel ”, "non-ferrous metal" and other 18 types of departments, each represented by English letters (marked between "JIS" and "×××× (standard number)" in the standard number). Related steel → G; Chemistry → K; Others (including test methods, welding, etc.) → Z. According to the nature of JIS standard content, it can be divided into: ② Test method standard
③ Basic standards. [1]
