protocols and diagnostic connector as prescribed in paragraph 6.5. of Annex II, Appendix 1. Any removable calibration memory chips shall be potted, encased in a sealed container or protected by electronic algorithms and shall not be changeable without the use of specialised tools and procedures.
              5.1.5.2. Computer-coded engine operating parameters shall not be changeable without the use of specialised tools and procedures (e. g. soldered or potted computer components or sealed (or soldered) computer enclosures).
              5.1.5.3. In the case of mechanical fuel-injection pumps fitted to compression-ignition engines, manufacturers shall take adequate steps to protect the maximum fuel delivery setting from tampering while a vehicle is in service.
              5.1.5.4. Manufacturers may apply to the Approval Authority for an exemption to one of these requirements for those vehicles which are unlikely to require protection. The criteria that the Approval Authority will evaluate in considering an exemption will include, but are not limited to, the current availability of performance chips, the high-performance capability of the vehicle and the projected sales volume of the vehicle.
              5.1.5.5. Manufacturers using programmable computer code systems (e.g. Electrical Erasable Programmable Read-Only Memory, EEPROM) shall deter unauthorised reprogramming. Manufacturers shall include enhanced tamper protection strategies and write protect features requiring electronic access to an off-site computer maintained by the manufacturer. Methods giving an adequate level of tamper protection will be approved by the authority.
              5.1.6. It shall be possible to inspect the vehicle for roadworthiness test in order to determine its performance in relation to the data collected in accordance with paragraph 5.3.7. of this Regulation. If this inspection requires a special procedure, this shall be detailed in the service manual (or equivalent media). This special procedure shall not require the use of special equipment other than that provided with the vehicle.
5.2.  Test procedure
                Table A illustrates the various possibilities for type approval of a vehicle.
              5.2.1.  Positive ignition engine-powered vehicles and hybrid electric vehicles equipped with a positive-ignition engine shall be subject to the following tests:
                Type I (verifying the average exhaust emissions after a cold start);
                Type II (carbon monoxide emission at idling speed);
                Type III (emission of crankcase gases);
                Type IV (evaporation emissions);
                Type V (durability of anti-pollution devices);
               Type VI (verifying the average low ambient temperature carbon monoxide and hydrocarbon exhaust emissions after a cold start);
   OBD-test.
              5.2.2.  Positive ignition engine-powered vehicle and hybrid electric vehicles equipped with positive-ignition engine fuelled with LPG or NG/biomethane (mono or bi-fuel) shall be subjected to the following tests (according to Table A):
               Type I (verifying the average exhaust emissions after a cold start);

               Type II (carbon monoxide emissions at idling speed);

               Type III (emission of crankcase gases);

               Type IV (evaporative emissions), where applicable;

               Type V (durability of
