ISO 12900:2018 PDF Download

The ISO 12900:2018 standard offers instructions and methods for figuring out how abrasive hard coal is. The standard describes a technique for calculating the abrasive characteristics of hard coal samples. For industries involved in coal processing and utilization, this knowledge is essential to assessing the potential effects of coal abrasiveness on machinery and manufacturing procedures.

The specification provides a methodical procedure for carrying out abrasion testing on hard coal. It outlines the apparatus and tools required, as well as the techniques for preparing samples needed to carry out these tests. The procedures for measuring abrasion characteristics such as mass loss, surface roughness, and volume loss are also covered in ISO 12900:2018. The calculation procedures for calculating the abrasiveness index of hard coal samples are specified in the standard.
