Foreword
GB/T 20462-2006 “Thermoplastic tubing and hoses for automotive use”
includes the following 2 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 edition).
This Part is identical to the translation of ISO 13775-2:2000.
For ease of use, this Standard also makes the following editorial changes:
a) The word “this International Standard” is changed to “this Part”;
b) USE the decimal point “.” instead of the comma “,” as a decimal point;
c) Delete the Foreword of the international standard.
Annex A in this Part is an informative annex. Annexes B and C are normative
annexes.
This Part was proposed by China Petroleum and Chemical Industry Association.
This Part shall be under the jurisdiction of Subcommittee 1 on Hose, China
National Standardization Technical Committee on Rubber and Rubber Products
(SAC/TC 35/SC 1).

Thermoplastic tubing and hoses for automotive use -
Part 2: Petroleum-based-fuel applications
1 Scope
This Part of GB/T 20462 specifies the construction, type, dimensions, test
requirements, and test methods for six types of extruded thermoplastic tubing
and hoses with a nominal bore of 2 mm~14 mm for use in petroleum-based-
fuel lines in vehicles powered by internal-combustion engines.
