Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 23338-2009 "internal combustion engine charge air cooler technical conditions", and GB/T 23338-2009 phase Than, except for editorial changes outside the main technical changes are as follows.

--- Remove the accuracy, precision, gauge terms and definitions (see the 2009 edition of Chapter 3);

--- Removed the symbols and abbreviations chapter (see the 2009 edition of Chapter 4);

--- Modify the heat transfer efficiency specified conditions and technical indicators (see 4.6, 2009 edition 5.6);

--- Modify the technical indicators of vibration resistance (see 4.7, 2009 version 5.7);

--- Modify the pressure pulse performance technical indicators (see 4.8, 2009 version 5.8);

--- Modify the thermal shock performance technical indicators (see 4.9, 2009 version 5.9);

--- Increased resistance to external corrosion performance of technical indicators and test methods (see 4.11,5.5);

--- Increased dropping hammer test technical indicators and test methods (see 4.12,5.6);

--- Modify the heat dissipation, resistance and heat transfer efficiency measurement methods (see 5.3, 2009 Edition 6.3).
