of Hydraulic Brake System Plastic Reservoir
Assembly
1 Scope
This Standard specifies the terms and definitions, performance requirements and
bench test methods of plastic reservoir for automotive hydraulic brake system.
This Standard is applicable to plastic reservoir for automotive hydraulic brake system;
plastic reservoir of automotive clutch master cylinders may be implemented by
reference.
2 Normative Reference

3 Terms and Definitions
For the purpose of this Standard, the following terms and definitions apply.
3.1 Maximum level
The highest position allowed to fill brake fluid during use of the reservoir; see Figure 1.
4.1.5.1 Total capacity. Measure according to 5.1.5.1 of this Standard; and the total
capacity of the reservoir shall meet the requirements of the product technical document.
4.1.5.2 Partition capacity. Measure according to 5.1.5.3 of this Standard; and the
partition capacity of any cavity of liquid storage chamber shall meet the design
requirements.
4.1.6 Strength of the installation part. This Standard shall test the reservoir directly
installed on the brake master cylinder according to 5.1.6 of this Standard. The reservoir
and the connection part with the master cylinder shall not be broken, cracked or
deformed; and shall be able to return to the original position after unloading.
4.1.7 Heat resistance. According to 5.1.7 of this Standard, the reservoir shall be free
of cracks, softening and deformation affecting functions. During the entire test, there
shall be no brake fluid overflowing from the reservoir. The brake fluid level of the
reservoir shall be clearly visible; the fluid level indicator shall meet the requirements of
4.2.1 and 4.2.2 of this Standard. For reservoir cover with screw-tightened structure,
the residual locking torque shall be no less than 50% of the initial tightening torque.
Other structures shall be in accordance with the provisions of the product technical
documents.
4.1.8 Cold resistance. Test according to 5.1.8 of this Standard; and the reservoir shall
be free of cracks and deformations that affect functions. The brake liquid level of the
reservoir shall be clearly visible; the liquid level indicator shall meet the requirements
of 4.2.1 and 4.2.2 of this Standard. For reservoir cover with screw-tightened structure,
the residual locking torque shall be no less than 50% of the initial tightening torque.
Other structures shall be in accordance with the provisions of the product technical
documents.
4.1.9 Temperature shock performance. Test according to 5.1.9 of this Standard; the
reservoir shall be free of cracks, softening and deformation that affects functions.
During the entire test, it should not have brake fluid overflow from the reservoir. The
brake liquid level of the reservoir shall be clearly visible; the liquid level indicator shall
meet the requirements of 4.2.1 and 4.2.2 of this Standard. For reservoir cover with
screw-tightened structure, the residual locking torque shall be no less than 50% of the
initial tightening torque. Other structures shall be in accordance with the provisions of
the product technical documents.
4.1.10 Vibration durability. Test according to 5.1.10 of this Standard. The reservoir shall
be free of cracks or damage; all parts shall be intact and work normally. During the
entire test, it should not have brake fluid overflow from the reservoir. The static
workability of the liquid level indicator shall meet the requirements of 4.2.1 of this
Standard. For reservoir cover with screw-tightened structure, the residual locking
torque shall be no less than 50% of the initial tightening torque. Other structures shall
be in accordance with the provisions of the product technical documents.
5.1.1.1 Block all liquid outlets of the reservoir.
5.1.1.2 Connect the brake fluid filling port of the reservoir to the vacuum source; and
after the absolute pressure of the system reaches (250±50) Pa; cut off the vacuum
source.
5.1.1.3 Measure and record the pressure rise value in the reservoir within 20s.
5.1.2 Pressure resistance.
5.1.2.1 Block all liquid outlets of the reservoir.
5.1.2.2 ...
