Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009
“Directive for standardization – Part 1. Structure and drafting of standards”.
This standard replaces QC/T 200-1995 (Performance requirements and test
methods of reservoir for air brake equipment of automobile and trailer). As
compared with QC/T 200-1995, the main technical changes are as follows.
(SEE Chapter 1; Chapter 1 of 1995 version);
- ADD the strength requirements for multi-chamber reservoir baffles (SEE
3.2.2 and 5.1.2);
- ADD the sealing requirements for one-way valve between multi-chamber
reservoir (SEE 3.3.2 and 5.2.2);
- MODIFY the test methods and evaluation methods for corrosion resistance
(SEE 3.4 and 5.3; 3.4 of 1995 version);
- ADD the requirements for test samples and test equipment (SEE Chapter
4);
(SEE Chapters 4 and 5 of 1995 version).
This standard was proposed by the National Automotive Standardization
Technical Committee (SAC/TC 114).
