  "heading": "If the emissions do not fulfil the requirements of point 3.1.0, then the occurrence of regeneration shall be verified. The verification of regeneration may be based on expert judgement through cross-correlation of several of the following signals, which may include exhaust temperature, PN, CO 2 , O 2 measurements in combination with vehicle speed and acceleration. If the vehicle has a regeneration recognition feature declared in Transparency List 1 set out in Table 1 of Appendix 5 to Annex II, it shall be used to determine the occurrence of regeneration. The manufacturer shall also declare in Transparency List 1 of set out in Table 1 of Appendix 5 to Annex II the procedure needed in order to complete the regeneration. The manufacturer may advise how to recognise whether regeneration has taken place in case such a signal is not available.",
  "text": "If regeneration occurred during the test, the result without the application of either the Ki -factor or the Ki offset shall be checked against the requirements of point 3.1.0. If the resulting emissions do not fulfil the requirements, then the test shall be voided and repeated once. The completion of the regeneration and stabilisation through at least 1 hour of driving shall be ensured prior to the start of the second test. The second test is considered valid even if regeneration occurs during it.",
