Specifies methods of testing certain performance characteristics.

1.1 This British Standard specifies methods of testing certain performance characteristics of fuel filters, strainers and sedimentors for compression-ignition engines using diesel fuel (gas-oil) of classes A1 or A2 as specified in BS 2869, with flow rates in the range 5 litres/h to 500 litres/h.

1.2 The requirements of this standard are applicable to fuel filters with replaceable elements and elements integral with the canister.
