This standard specifies the specifications of rubber and plastic hoses, the maximum and minimum allowable inner diameters of each specification, and the cut length tolerances of industrial and motor vehicle hoses. According to the manufacturing process, the hose is divided into four types. Except for the hose specifications and inner diameter ranges that are specially specified, this standard is used together with the relevant hose product standards.
