              Introduction
The intention of this Regulation is to establish uniform provisions concerning the approval of motor vehicles with regard to the emissions of light-duty vehicles based on the new World harmonized Light vehicle Test Procedure (WLTP) included in UN GTR No. 15 and the updated Evaporative Emissions test procedure (Type 4 test) which has been developed in UN GTR No. 19. It will enable Contracting Parties (CPs) to issue and accept approvals based on these new type approval tests.
The WLTP Type 1 test replaces both the current Type 1 test in UN Regulation No. 83 and UN Regulation No. 101, whilst the updated Evaporative Emissions test procedure (Type 4 test) replaces that currently in UN Regulation No 83.
In addition, this new Regulation includes an update to the Type 5 test for verifying the durability of pollution control devices and updated On-Board Diagnostic (OBD) requirements. These updates are in order to reflect the changes from the previous NEDC based Type 1 test to the new WLTP Type 1 test.
The 02 series of this Regulation covers two sets of requirements – termed Level 1A and Level 1B. Level 1A is based on a four phase test cycle (Low, Medium, High and Extra-High), whilst Level 1B is based on a three phase test cycle (Low, Medium and High), with different type 1 limits applying to these different levels. The majority of the regulatory text is applicable to both Level 1A and Level 1B. Where the requirements are specific to either Level 1A or Level 1B the relevant sections are labelled accordingly. This series of amendments covers regional requirements and does not require mutual recognition by other Contracting Parties.
The 03 series of this Regulation includes a harmonised procedure which contains the most stringent procedures/limits which shall be subject to full mutual recognition. A type approval to the 03 series shall therefore be accepted by all CPs having adopted this Regulation.
              1. Scope
              This Regulation provides requirements for two levels of approval. One level requires testing using a 4-phase WLTC (low, medium, high and extra-high as defined in Annex B1) – this is called Level 1A. The second level requires testing using a 3-phase WLTC cycle (low, medium and high as defined in Annex B1) – this is called Level 1B.
