Remark. 6.5.1. If the structural layout of the engine is such that the test cannot be performed by the methods described in paragraphs 6.1. to 6.4. of this annex, the measurements shall be effected by that method modified as follows: 6.5.2. Before the test, all apertures other than that required for the recovery of the gases shall be closed; 6.5.3. The bag shall be placed on a suitable take-off which does not introduce any additional loss of pressure and is installed on the recycling circuit of the device directly at the engine-connection aperture (see diagram below). 70 Type 3 test Annex 7 Reserved Annex 8 (Verifying the average exhaust emissions of carbon monoxide and hydrocarbons after a cold start at low ambient temperature)
