Immediately before Schedule A1 insert the following Schedule—

“SCHEDULE AA1

Environmental Specifications for Petrol and for Diesel Fuel

Regulation 3

Petrol

Parameterf1	Unit	Limitsf2
		(1) Test methods must be those specified in BS EN 228:2012. An analytical method specified in a replacement to BS EN 228:2012 can be used if it can be shown to give at least the same accuracy and at least the same level of precision as the analytical method it replaces.
(2) The values quoted in the specification are ‘true values’. In the establishment of their limit values, the terms of BS EN ISO 4259:2017 have been applied and in fixing a minimum value, a minimum difference of 2R above zero has been taken into account (R= reproducibility). The results of individual measurements must be interpreted on the basis of the criteria described in BS EN ISO 4259:2017.
(3) The summer period is the period specified in regulation 5(2).
(4) Other mono-alcohols and ethers with a final boiling point no higher than that stated in BS EN 228:2012.

		(1) Test methods must be those specified in BS EN 590:2013. An analytical method specified in a replacement to BS EN 590:2013 can be used if it can be shown to give at least the same accuracy and at least the same level of precision as the analytical method it replaces.
(2) The values quoted in the specification are ‘true values’. In the establishment of their limit values, the terms of BS EN ISO 4259:2017 have been applied and in fixing a minimum value, a minimum difference of 2R above zero has been taken into account (R= reproducibility). The results of individual measurements must be interpreted on the basis of the criteria described in BS EN ISO 4259:2017.
