- Synopsis
- The deliberation was commenced after the deregulation promotion plan was determined upon the cabinet decision in 1995. The revision of JIS on testing methods of concrete has been done for three years from 1995 to 1997. As for the testing methods of aggregate for concrete, six standards, namely JIS A 1102, 1104, 1109, 1110, 1134 and 1135, were revised to be consistent with international standards. This paper describes the comparison of JIS with ISO standards on testing methods of aggregate for concrete and the major changes in the revised JIS in June 1999.
