This Part of BS 5885 specifies minimum requirements for automatic forced and induced draught packaged gas burners with heat input ratings of 7.5 kW up to but excluding 60 kW and capable of operating with 1st, 2nd or 3rd family gases at pressures not exceeding 35 mbar¹⁾ at the inlet to the control train supplied with the burner.

BS 5885 applies to burners intended for use in industrial processes. It does not cover burners intended for use in heating appliances, e.g. boilers, which are covered by BS EN 676, Automatic forced draught burners for gaseous fuels.

It covers single burners, and dual fuel burners when operating only on gas. It does not cover multi-burners.

It relates primarily to the safety aspects of automatic control and operation. It does not provide a complete specification for automatic burners and their ancillary equipment.

NOTE 1 The use of gases which are dirty, wet, of variable composition or high dewpoint may cause difficulties which are not covered in detail by this Part of BS 5885. In such cases, suppliers and users of equipment will need to take additional measures to comply with the requirements of this standard.
