Foreword
All technical contents in this Standard are mandatory.
This Standard was drafted as per the rules specified in GB/T 1.1-2009.
This Standard replaced GB 18296-2001 Safety Property Requirements and Test
Methods for Automobile Fuel Tank. Compared with GB 18296-2001, this Standard has
the major differences as follows:
--- Modify the standard name into Safety Property Requirements and Test Methods
for Automobile Fuel Tank and Its Installation.
--- Modify the scope of application of the standard from “this Standard specifies the
safety property requirements and test methods for automobile fuel tank with
gasoline and diesel as the fuel” to “this Standard specifies the safety property
requirements and test methods for automobile fuel tank filled with liquid fuel; and
the safety requirements for installation on the automobile”; meanwhile, add the
application of the Class-O automobile (see Clause 1 of this Edition; Clause 1 of
2001 Edition);
--- Add the requirements and test methods for fuel tank overturn test (see 4.1.7, 5.2
of this Edition);
--- Add fuel permeability requirements and test methods for plastic fuel tank (see
4.1.10, 5.5 of this Edition);
--- Add fuel resistance requirements and test methods of plastic fuel tank (see 4.1.11,
5.6 of this Edition);
--- Modify the fire resistance test method of the plastic fuel tank (see 4.1.12 of this
Edition; 3.10 of 2001 Edition);
--- Add the safety requirements for fuel tank installation (see 4.2 of this Edition);
--- Delete the technical requirements and test methods of plastic fuel tank vibration
(see 3.5, 4.3 of 2001 Edition);
--- Delete the requirements and test methods for the opening pressure of the safety
valve; introduce the automatic pressure compensation devices to balance the
pressure inside and outside the fuel tank (see 3.4, 4.2 of 2001 Edition).
The technical contents in this Standard refers to the Economic Commission for Europe
ECE R34 Uniform Regulations on the Certification of Fire Resistance of Vehicle (03
Revision, 2015 Edition)
This Standard was proposed by and under the jurisdiction of Ministry of Industry and
Information Technology.

Safety Property Requirements and Test Methods
for Automobile Fuel Tank and Its Installation
1 Scope
This Standard specifies the safety performance requirements and test methods of
automobile fuel tank containing liquid fuel.
This Standard also specifies the safety requirements for the installation of automobile
fuel tank on the vehicles.
This Standard is applicable to the metal and plastic fuel tank of the Type-M, Type-N,
and Type-O automobiles.
2 Normative References
The following documents are essential to the application of this document. For the
dated documents, only the versions with the dates indicated are applicable to this
document; for the undated documents, only the latest version (including all the
amendments) are applicable to this document.

Duty Vehicles (CHINA 6)
3 Terms and Definitions
For the purpose of this document, the following terms and definitions apply.
3.1 Automobile fuel tank
An independent tank assembly fixed on an automobile for storing fuel; is assembled
by a fuel tank, a filler pipe, a filler port, a fuel tank cover, a pipe joint, and other auxiliary
devices.
NOTE: it is referred to as fuel tank in this Standard.
3.2 Capacity of the fuel tank
In the fuel tank design parameters, the fuel filling volume specified by the manufacturer.
NOTE: it is referred to as rated capacity.
3.3 Liquid fuel
The fuel that is liquid under normal temperature and pressure conditions.
NOTE: it is referred to as fuel in this Standard.
3.4 Leakage of fuel
The fuel drops in a linear or drip form from the fuel tank.
3.5 Fuel permeability
The fuel is lost due to molecular diffusion in the fuel tank.
3.6 Automatic compensating pressure device
The device for automatically compensating the working pressure or safety pressure of
the fuel tank.
NOTE: such as vent valve, safety valve, etc.
3.7 Working pressure of the fuel tank
The pressure above the liquid level in the fuel tank under normal automobile use
conditions.
NOTE: it is referred to as working pressure in this Standard.
4 Safety Property Requirements
4.1 Fuel tank
4.1.1 The fuel tank shall be resistant to corrosion.
4.1.2 The fuel tank shall be made of fire-resistant metal material, or it may be made of
plastic that meets the requirements of this Standard.
4.1.3 The fuel tank shall be equipped with automatic compensating pressure device
(such as vent valves, safety valves, etc.).
4.1.4 The fuel tank cover shall be able to fix onto the filler pipe. In the case of the fuel
tank cover is lost, if there are measures to prevent excessive evaporation of the fuel
and fuel overflow, then it is considered to meet the requirements of this Clause.
Specifically, the following methods can be used:
a) A non-removable fuel tank cover that opens and closes automatically;
b) Any other measures that have the same effect. For example (including but not
limited to), drawstring fuel tank cover, chain fuel tank cover, etc.; or the fuel tank
cover using the same key as the ignition key (in this case, only when the fuel
tank cover is locked, can the key remove from the fuel tank). However, for the
Type-M1, and Type-N1 vehicles, it is not enough to use only the drawstring or
chain fuel tank covers.
4.1.5 The seal between the fuel tank cover and the filter port shall be firm and reliable.
When locked, the fuel tank cover ...
