The article analyses the method of testing the abrasion resistance of sandstones on Böhme abrasion test apparatus and describes the problems related to the implementation of this test, as well as the interpretation of the results. The tests were conducted in accordance with the requirements of the EN14157 standard on 14 samples of dry and water-saturated sandstones. The analysis of the results showed that the correlation coefficient for the results obtained in the case of dry samples tests in relation to water saturation was 0.944. It was also observed that the loss of volume during the abrasion process in the individual stages of the test is smaller with the increase of rotation on the disc. In the case of dry samples abrasion, the reason for this is the mixing of abrasive grain and worn stone. In the case of samples tested under conditions of water saturation, the sample is covered with the abrasive grain, which in further phases is liquefied and mixed with the worn stone mass. In this case, however, the abrasion is worse in comparison with the samples tested in the dry condition, because the liquid and mixed abrasive grain with the worn rock mass causes the sample to slide, which in turn results in the abrasion volume loss. The control of the abrasion resistance results obtained from the stone abrasion according to the EN14157 standard should be a comparison with the abrasion resistance results obtained in the process of calculating the abrasion volume loss of sample determined from height.

本文分析了在伯曼磨耗测试仪上测试砂岩耐磨性的方法，并描述了与该测试的实施相关的问题以及对结果的解释。根据EN14157标准的要求，对14个干和水饱和的砂岩样品进行了测试。结果分析表明，在干样品测试的情况下，与水饱和度相关的结果的相关系数为0.944。还可以观察到，随着磨盘旋转的增加，在测试的各个阶段的磨损过程中体积损失较小。对于干燥的样品磨损，其原因是磨料颗粒和磨损的石材混合在一起。对于在水饱和条件下测试的样品，样品上覆盖有磨料颗粒，该磨料颗粒在其他阶段被液化并与磨损的石材混合。然而，在这种情况下，与在干燥条件下测试的样品相比，磨损更差，因为液体和混合的磨粒与磨损的岩块会导致样品滑动，进而导致磨损量的损失。根据EN14157标准对石材磨耗获得的耐磨性结果的控制应与在计算从高度确定的样品的磨耗量损失的过程中获得的耐磨性结果进行比较。然而，与在干燥条件下测试的样品相比，磨损更差，因为液体和混合的磨料颗粒与磨损的岩体会导致样品滑动，进而导致磨损量的损失。根据EN14157标准对石材磨耗获得的耐磨性结果的控制应与在计算从高度确定的样品的磨耗量损失的过程中获得的耐磨性结果进行比较。然而，与在干燥条件下测试的样品相比，磨损更差，因为液体和混合的磨料颗粒与磨损的岩体会导致样品滑动，进而导致磨损量的损失。根据EN14157标准对石材磨耗获得的耐磨性结果的控制应与在计算从高度确定的样品的磨耗量损失的过程中获得的耐磨性结果进行比较。
