在一个名为“面向消费者的固体运输技术”(COSTT)的合作研究项目中，开发了一种单轴结块测试仪，用于测量散装固体在受控环境条件下的结块倾向。为了验证从该测试仪获得的结果，使用一种已知与湿度相关的有机酸作为测试材料，进行了一系列循环测试。这些试验表明，在试验过程中，即使是看起来很小的偏差，也会导致测量的单轴强度出现重大偏差。本文指出了进行可靠的结块测试所需的详细程度和可获得的重现性。
In a collaborative research project called “Consumer Oriented Solids Transport Technology” (COSTT), a uniaxial caking tester was developed to measure the caking propensity of bulk solids under controlled environmental conditions. To validate the results gained from this tester, a series of round robin tests were run, using an organic acid of known humidity dependence as test material. These tests showed that even seemingly minor deviations in the test procedure can cause significant deviations in the measured uniaxial strength. This paper gives an indication of the level of details required to run a reliable caking test and the obtainable reproducibility.
