This standard specifies the type and basic number, marking, technical requirements, test methods and table and color matching of ball-coupled cooling pipes. Only the cooling system of machine tools with a resistance not exceeding 0.4M can be used as a reference for other cooling systems. The following provisions are included in the standard and shall become the standard text of this standard by citing it in the standard. This standard is marked as a self-validation version. All standards are subject to revision. The commonality of this standard is to reduce the possibility of using the following standard new versions.
