of the tests described in paragraphs 4.3.2. to 4.3.2.7. may be used for this purpose.
4.5.6. The malfunction indicator shall not activate during vehicle operation required by paragraphs 4.3.2. to 4.3.2.7.
              4.6. Requirements regarding compatibility with the NOx control measures (applicable only to replacement pollution control devices to be fitted to vehicles equipped with sensors directly measuring NOx concentration in the exhaust).

              4.6.1. NOx control measures compatibility demonstration is required only when the original pollution control device was monitored in the original configuration.

              4.6.2. The compatibility of the replacement pollution control device with the NOx control measures shall be demonstrated by using the procedures described in Annex 11 to this Regulation, for replacement pollution control devices intended to be fitted to engines or vehicles type approved in accordance with this Regulation.

              4.6.3. Reserved

              4.6.4. The replacement pollution control device manufacturer may use the same preconditioning and test procedure as used during the original type approval. In that case, the approval authority which granted original type approval of an engine of a vehicle shall provide, on request and on a non-discriminatory basis, an information document presented as an appendix to the Information Document provided for in Annex I, which contains the number and type of preconditioning cycles and the type of test cycle used by the original equipment manufacturer for NOx control measures testing of the pollution control device.

              4.6.5. Paragraph 4.5.5. shall apply to NOx control measures monitored by the OBD system.

5.  Conformity of production
5.1. Measures to ensure the conformity of production shall be taken in accordance with paragraph 8. of this Regulation.
5.2. Special provisions
5.2.1. The checks referred to in Appendix 2 to the 1958 Agreement (E/ECE/324//E/ECE/TRANS/505/Rev.2) shall include compliance with the characteristics as defined under "type of pollution control device" in paragraph 1.2.1.
5.2.2. For the application of paragraph 8. of this Regulation, the tests described in paragraph 4.3. of this annex (requirements regarding emissions) may be carried out. In this case, the holder of the approval may request, as an alternative, to use as a basis for comparison not the original equipment pollution control device, but the replacement pollution control device which was used during the type approval tests (or another sample that has been proven to conform to the approved type). Emissions values measured with the sample under verification shall then on average not exceed by more than 15 per cent the mean values measured with the sample used for reference.
