The specifications begin with the prefix JIS, followed by a letter, where the letter denotes the area of division, followed by four digits. Japanese JIS standards are widely used in Asia and the Pacific areas. JIS steel specifications have also often been used as a base for other national systems, such as Korean, Chinese, and Taiwanese.
JIS standards are developed by the Japanese Industrial Standards Committee (JISC) in Tokyo with an aim to promote the industrial standards of Japan. The below list contains standards for the following material categories:
For more information on the JIS designation system see Introduction to the JIS Standard Designation System.
The list of standards below covers a wide range of materials and applications a few of which are:
