This chapter describes the determination of brake specific emissions of gaseous and particulate pollutants on engines to be tested. The test engine shall be the parent engine configuration for the engine family as specified Annex IX to Implementing Regulation (EU) 2017/656.

A laboratory emission test consists of measuring emissions and other parameters for the test cycles specified in Annex XVII. The following aspects are treated:

1. (a)

   The laboratory configurations for measuring the emissions (point 7.2);

2. (b)

   The pre-test and post-test verification procedures (point 7.3);

3. (c)

   The test cycles (point 7.4);

4. (d)

   The general test sequence (point 7.5);

5. (e)

   The engine mapping (point 7.6);

6. (f)

   The test cycle generation (point 7.7);

7. (g)

   The specific test cycle running procedure (point 7.8).
