To meet the needs of rail grinding machines and other equipment，Combined with the actual needs of China Railway Group standards and measurement work，Convert 16 original railway industry standards such as "General Technical Conditions for Rail Grinding Machines" (TB/T 1926-2004), which are no longer managed as railway industry standards, into State Railway Group technical standards;willNo longer managed as a national metrology technical specification《Train rear safety protection device main engine test bench》Converted to China Railway Group Measurement Standards。
