607300-000020-0000501 Scope
Replacement:
This part of IEC 60730 applies to automatic electrical
burner control systems
for the automatic control
of burners for oil, gas, coal or other combustibles intended to be used • for household and similar use,
• in shops, offices, hospitals, farms and commercial and industrial applications.
This International Standard is applicable
• to a complete
burner control system
, • to a separate
programming unit
, • to a separate electronic high-voltage
ignition source
, • to a separate
flame detector
and • to a separate
high-temperature operation (HTO) detector
. • to a
burner control system
intended to be used in warm air heating appliances (furnaces) where the appliance is equipped with an electromechanical differential pressure control to monitor the difference of the combustion air pressure (Type 2.AL). This pressure control provides a switch as an alternative to one of the two switching elements to directly de-energize the safety relevant terminals. NOTE 1 Throughout this document, where it can be used unambiguously, the word "system" means "burner control system" and "systems" means "burner control systems".
NOTE 2 Throughout this document, the word "equipment" means "appliance and equipment."
This standard does not apply to thermoelectric flame supervision controls; thermoelectric flame supervision controls are covered by ISO 23551-6.
This document also applies to electrical
burner control systems
intended exclusively for industrial process applications e.g. those applications covered by ISO TC 244 (ISO 13577). This document applies to controls powered by primary or secondary batteries, requirements for which are contained within the standard, including Annex V.
Modification of 1.1 of the Part 2 by adding the following: Components of burner control systems such as electrodes, flame supervision, oxygen depletion safety shut-off systems (ODS), thermoelectric safety shut-off devices, pilot burners, thermocouples, fast-acting thermocouples, and other components are covered by this Part 2-5. (Refer to Annex DVKK.)
Modification of 1.1 of the Part 2 by adding the following note: NOTE 3DV Requirements for separate ignition transformers are covered in UL 506 and CSA C22.2 No. 13.
Modification of 1.1 of the Part 2 by adding the following: In Canada, this Standard applies to equipment that is intended to be installed or used in accordance with CSA C22.1, Canadian Electrical Code, Part I. In Canada, general requirements applicable to these products are provided in CSA C22.2 No. 0.
1 1.1 This document applies to the inherent safety, to the declared
operating values
, operating times
and operating sequences
where such are associated with burner safety and to the testing of automatic electrical burner control systems
used in, on, or in association with, burners. NOTE Requirements for specific
operating values
, operating times
and operating sequences
are given in the standards for appliances and equipment.
1 1.2 This document applies to AC or DC powered systems with a rated voltage not exceeding 660 V AC or 600 V DC.
1 1.3 This document does not take into account the
response value
of an automatic action
of a control
, if such a response value
is dependent upon the method of mounting the control in the equipment. Where a response value
is of significant purpose for the protection of the user, or surroundings, the value defined in the appropriate equipment standard or as determined by the manufacturer applies.
1 1.4 This document applies also to systems incorporating
electronic devices
, requirements for which are contained in Annex H.
Modification of 1.1.4 of the Part 2 by adding the following: This Standard also applies to manufacturing and production testing (see Annex DVLL) and solid-state oil igniters (see Annex DVMM).
1 1.5 This document applies to systems using NTC or PTC thermistors, additional requirements for which are contained in Annex J.
1 1.6 This document includes systems responsive to flame properties and temperature for HTO.
1 1.7 This document applies to the electrical and functional safety of controls capable of receiving and responding to communications signals. The signals may be transmitted to or received from external units, connected wired or wireless, that may or may not be part of the burner control system.
1 1.8 This document does not address the integrity of the output signal to the network devices, such as interoperability with other devices, unless it has been evaluated as part of the control system.
