GB/T 20462—2006 "Thermoplastic non-reinforced tubing and hoses for automotive use" comprises the following two parts: ——Part 1: Non-fuel applications; ——Part 2: Petroleum-based-fuel applications. This part is Part 2 of GB/T 20462—2006. This part is identical to ISO 13775-2:2000 "Thermoplastic tubing and hoses for automotive use — Part 2: Petroleum-based-fuel applications" (English version). This part is an equivalent translation of ISO 13775-2:2000. For ease of use, the following editorial modifications have been made to this standard: a) The term "this International Standard" has been changed to "this part"; b) The comma "," used as a decimal mark has been replaced by the decimal point "."; c) The foreword of the International Standard has been deleted. Appendix A of this part is an informative appendix, while Appendix B and Appendix C are normative appendices. This part was proposed by the China Petroleum and Chemical Industry Association. This part is under the jurisdiction of the Hose Subcommittee of the National Technical Committee on Rubber and Rubber Products Standardization (SAC/TC 35/SC1). This part was drafted by Taizhou Changli Resin Tube Co., Ltd. The main drafters of this part are Peng Weixiang, Wang Yimin, and Yao Qin. This part is the first release. Introduction This part specifies requirements for extruded thermoplastic non-reinforced tubing and hoses used in non-fuel systems of automotive vehicles. Additionally, it may be used as a classification system to enable original equipment manufacturers (OEMs) to detail test "material designations" for special applications not covered by the four main types (see examples in Appendix A). In such cases, the non-reinforced tubing or hose shall not bear any marking indicating this part number, but may detail the OEM's own identification marking as shown in its part drawing.
