GB/T 9575-2013Rubber and plastics hoses -- Hose sizes, minimum and maximum inside diameters, and tolerances on cut-to-length hoses (English PDF)

GB/T 9575-2013 is the English-translated version of 橡胶和塑料软管 软管规格和最大最小内径及切割长度公差.

GB/T 9575-2013 — This standard specifies the minimum and maximum internal diameter of rubber and plastic hose specifications and specifications of each allowable values \u200b\u200band industrial and motor vehicle hoses Cut length tolerances.

According to the manufacturing process, the hose is divided into four types. In addition to the special provisions of the inside diameter hose specifications and scope of this standard hose associated with product standards used together.

Specifications and tolerances of the inner diameter of 2 Rubber and plastic hose specifications and the inner diameter of each range should be consistent with Table 1.

Rubber and plastic hoses in accordance with the manufacturing process is divided into four Typed. --- A Type. hard core forming a hose; --- B type. soft core molding hose (including the use and non-use of plastic die manufacturing hydraulic hoses); --- C type. coreless molded hose; --- D Type. extruded plastic hose (D type does not include spiral reinforced plastic hose to attract and discharge, which are classified as Type C).
