This British Standard specifies requirements for eight classes of
petroleum fuels for engines and boilers used in agricultural, domestic
and industrial applications.
This British Standard does not preclude lawful use of one class of
fuel in an application designed for use with a fuel of another class.
However, it is strongly recommended that only class C1 burner fuel is
used in flueless domestic appliances, and it is advisable that tests or
consultation with the equipment manufacturer are carried out if fuel
is to be used for a purpose other than that for which it is classified in
this British Standard.
NOTE Annex A, Annex B and Annex C provide information on fuel types
and applications, storage and handling, and properties of fuels respectively.
Additional information on storage and handling is given in BS 6380.
