Synopsis
Aggregate to be subjected to testing must be representative of the lot to be tested, and if the reduction of the sample of aggregate is done improperly, accurate assessment of the quality of that lot of aggregate is not possible. In other words, the obtainment of accurate test results requires the standardization of not only the test conditions, but also the aggregate sample reduction method. This paper outlines the contents of the JIS A 1158 (Method for reducing samples of aggregate to testing size) standard, which covers the aggregate sample reduction method.
