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 1 of GB/T 20462-2006.
This Part is identical to ISO 13775-1:2000 “Thermoplastic tubing and hoses for
automotive use - Part 1: Non-fuel applications” (English edition).
This Part is identical to the translation of ISO 13775-1:2000.
For ease of use, this Part 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.

Thermoplastic tubing and hoses for automotive use -
Part 1: Non-fuel applications
1 Scope
This Part of GB/T 20462 specifies the construction, type, dimensions, test
requirements, and test methods for four types of extruded thermoplastic tubing
and hoses with a nominal bore of 2 mm~14 mm for use in vehicles powered by
internal-combustion engines, excluding use in air braking systems (see ISO
7628-2:1998), fuel lines (see GB/T 20462.2) and high-pressure hydraulic
systems.

3 Classification and materials
Four types of tubing and hose for specific applications are specified as follows:
Type 1: tubing or hose for vacuum and electronic control;
Type 2: tubing or hose for coolant systems;
Type 3: tubing or hose for screen/headlamp wash systems;
Type 4: tubing or hose for exhaust gas recirculation systems.
The product shall consist of an extruded thermoplastic material with or without
an integral reinforcement. The product may also have an inner veneer to impart
improved fluid resistance and/or heat resistance. It may also have an extruded
outer cover to improve environmental resistance and/or flame resistance. The
outer cover is not necessarily bonded to the tubing or hose.
4 Dimensions
The nominal bore, internal diameter and tolerance, and minimum wall thickness
of the tubing and hose shall comply with Table 1.
The wall thickness shall be the sum of the individual thicknesses of the various
