replacement pollution control device in such a way as to be clearly legible and indelible. It shall, wherever possible, be visible when the replacement pollution control device is installed on the vehicle.
3.4. An example of the type approval mark for a separate technical unit is given in Appendix 3 to this annex.
3.5. Notice of approval or of extension or of refusal of approval or production definitively discontinued of a replacement pollution control device pursuant to this Regulation shall be communicated to the Parties to the 1958 Agreement which apply this Regulation, by means of a form conforming to the model in Appendix 2 to this annex. Values measured during the type test shall also be shown.
4.  Technical requirements
4.1. General requirements
4.1.1. The replacement pollution control device shall be designed, constructed and capable of being mounted so as to enable the engine and vehicle to comply with the rules with which it was originally in compliance and that pollutant emissions are effectively limited throughout the normal life of the vehicle under normal conditions of use.
4.1.2. The installation of the replacement pollution control device shall be at the exact position of the original equipment pollution control device, and the position on the exhaust line of the exhaust gas, temperature and pressure sensors shall not be modified.
4.1.3. If the original equipment pollution control device includes thermal protections, the replacement pollution control device shall include equivalent protections.
4.1.4. Upon request of the applicant for the type approval of the replacement component, the Type Approval Authority that granted the original type approval of the engine system shall make available on a non-discriminatory basis, the information referred to in paragraphs 3.2.12.2.6.8.1.1. and 3.2.12.2.6.8.2.1. in Part 1 of the information document contained in Annex 1 for each engine to be tested.
4.2. General durability requirements
The replacement pollution control device shall be durable, that is designed, constructed and capable of being mounted so that reasonable resistance to the corrosion and oxidation phenomena to which it is exposed is obtained, having regard to the conditions of use of the vehicle.
The design of the replacement pollution control device shall be such that the elements active in controlling emissions are adequately protected from mechanical shock so as to ensure that pollutant emissions are effectively limited throughout the normal life of the vehicle under normal conditions of use.
The applicant for type approval shall provide to the Type Approval Authority details of the test used to establish robustness to mechanical shock and the results of that test.
4.3. Requirements regarding emissions
4.3.1. Outline of procedure for evaluation of emissions
The engines indicated in paragraph 3.4.4. (a) of this Regulation equipped with a complete emissions
