Abstract
The regulatory Japanese leaching test (JLT13) was greatly revised in the year 2013. This report describes the details of the revised contents (leaching process, solid/liquid separation process, chemical analysis, etc.). In particular, it is important for analytical technicians to understand why certain items needed modification. The modified contents are discussed here, with the inclusion of experimental data and scientific reports by the committee of experts who decided upon the changes. After the completion of the revision, an accuracy and precision survey will be conducted for the JLT13 test in 2014.
