Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard uses the redrafting method to modify and adopt UIC 6240:2006
"Exhaust emission tests for diesel traction engines" (English version).
This standard replaces TB/T 2783-2006 "Exhaust emission tests for railway
diesel traction engines". Compared with TB/T 2783-2006, the main technical
changes of this standard are as follows:
- ADD normative references (see Chapter 2)
- DELETE the cost of technical approval (see Chapter 7 of the 2006 edition);
- MODIFY the emission limits of pollutants (see Table A.1; Table A.1 of the
2006 edition);
- DELETE the smoke limit requirements (see the column of Bosch smoke in
Table A.1 as well as the Figure A.1 and Figure A.2 of the 2006 edition);
- DELETE the list of accreditation bodies and diesel engines that have
passed the UIC emission test (see Appendix F and Appendix G of the 2006
edition);
- MODIFY the RB name of the accreditation body to the China Railway
Certification Body (see 3.3, 4.2; 2.3, 3.2, 4.2, 4.3, 4.4, 5.1.3, 5.1.4, 5.2.1,
5.2.2, 5.2.4, 5.3.1, 5.3.2 and Appendix E of the 2006 edition);
- DELETE the description of the responsibilities of the Diesel Engine Expert
Committee of ERRI (European Railway Research Institute); CLARIFY that
the only organization responsible for technical accreditation is the China
Railway Certification Agency (see 5.3.2, 5.3.3, 6.1.1, 6.1.3 and Appendix H
of the 2006 edition).
The main editorial differences between this standard and UIC 6240:2006 are
as follows:
- DELETE the "Foreword" and "References" of UIC 624;
- For UIC standards and ISO standards cited in UIC 624, if they have been
adopted as Chinese standards, use the Chinese standards to replace the
corresponding UIC standards and ISO standards;
- CORRECT the editable error of "P ≤ 560 kW" in Appendix A of UIC 624 to
"560 kW < P ≤ 2000 kW" (see column 6 in Table A.1).
Exhaust emission tests for diesel engines of motive
power units
1 Scope
This standard specifies the limits of pollutants emitted by diesel engines for
railway traction and the methods for determining these emissions.
This standard applies to railway traction diesel engines, new railway traction
equipment or diesel engines reinstalled from existing traction equipment. It
does not apply to special-purpose locomotive diesel engines (such as oil
refineries or mining locomotives) and diesel engines with a transmission power
of less than 100 kW.

5 Apply for emission test
5.1 The diesel engine manufacturer shall submit a test application to the
certification agency.
5.2 The manufacturer shall provide the following information to the railway
management department and certification agency:
- A copy of the diesel engine manual as specified in TB/T 2745;
- All the details of the test bench used.
5.3 The certification agency shall check all the submitted application documents
and technical instructions.
6 Implementation of the test
6.1 Test organization
6.1.1 The emission test shall not exceed 90 days from the time of application to
the implementation of supervisory measurement.
6.1.2 The certification agency and the user shall jointly discuss with the
manufacturer to determine the specific test scheme; the certification agency
shall report to the railway management department for approval.
6.1.3 The work to be done on the test bench and the tested diesel engine:
- The certification agency shall confirm that the test bench meets the
requirements;
- According to the diesel engine's characteristic curve as specified in TB/T
2745, it shall be measured at the presence of a representative of the
certification agency or a test supervisor of the railway management
department.
6.2 Supervision of the test
6.2.1 Representatives of the certification agency, and test supervisors or their
representatives from the railway management department, when necessary,
shall be present at site for supervision; it shall perform emission measurement
according to the F cycle and/or C1 cycle in GB/T 8190.4-2010.
6.2.2 The manufacturer is only responsible for the conduct of the test. The task
of the certification agency is essentially to certify the test items and the results
obtained.
6.2.3 When the measurement is over, a fuel sample for the test shall be taken
and sent to an independent laboratory accredited by the certification agency for
analysis.
6.2.4 Based on the completed analysis results, the test supervisors and
certification agency's representatives of the railway management department
shall:
