| Abstract;This paper explains the following items on the titled method: 1) Conventional prediction methods based on sampling are inadequate in applying to multicomposition wastes (I) due to being based on a single component waste, 2) application results of a theoretically obtained equation in the preceding paper to four kinds of I to determine required sampling weights; application to the standard leaching test No. 13 issued by Ministry of Environment provided required sampling weight and fractionated weight to be 25 kg and 110 g, respectively, wherein variation coefficient of test results was 1.1, which level thus should be accepted in practical sampling of I and 3) statistic analysis of test data taking into consideration of variation provided that test results would exceed the standard value with not less than 10 % probability, when the average test value in five repeated tests is not less than 0.6 times the standard value. |
