This Annex describes the procedure for type IV testing, as referred to in Part A of Annex V to Regulation (EU) No 168/2013. 1.2. Appendix 1 describes the procedure for testing the permeability of non-metallic fuel tank material and shall also be used as preconditioning test cycle for fuel storage testing referred to in Number C8 of Annex II to Regulation (EU) No 168/2013. 1.3. Appendices 2 and 3 describe methods for the determination of the loss of hydrocarbons by evaporation from the fuel systems of vehicles equipped with a propulsion type that uses volatile, liquid fuel. Appendix 4 sets out the calibration procedure for evaporative emission test equipment. 2. General requirements 2.1. The vehicle manufacturer shall prove to the technical service and to the satisfaction of the approval authority that the fuel tank and fuelling system are leak-tight. 2.2. The fuelling system tightness shall comply with the requirements referred to in Annex II (C8) to Regulation (EU) No 168/2013. 2.3. All L-vehicle (sub-)categories equipped with a non-metallic fuel storage shall be tested according to the permeability test procedure laid down in Appendix 1. At the request of the manufacturer, the fuel permeation test set out in Appendix 2 or the SHED test set out in Appendix 3 may replace the evaporative part of the permeability test set out in Appendix 1. 2.4. L-vehicle (sub-)categories L3e, L4e, L5e-A, L6e-A and L7e-A shall be tested according to the SHED test procedure laid down in Appendix 3. 2.5. The fuel permeation test procedure set out in Appendix 2 shall be subject to the general assessment in the environmental effect study referred to in point 5(b) of Article 23 of Regulation (EU) No 168/2013. This study shall confirm whether L-vehicle (sub-)categories L1e-A, L1e-B, L2e, L5e-B, L6e-B, L7e-B and L7e-C shall be tested either according to the permeation test procedure set out in Appendix 2 or the SHED test procedure set out in Appendix 3. 2.6. If an L1e-A, L1e-B, L2e, L5e-B, L6e-B, L7e-B and L7e-C vehicle is to be subject to a SHED test procedure set out in Part C of Annex VI to Regulation (EU) No 168/2013 and in Appendix 3, it shall be exempted from the fuel permeation test procedure set out in Appendix 2 and vice versa.
