WG 1 - TC 72/WG 1

IEC 60730-2-5:2026 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;
NOTE 1 Throughout this document, where it can be used unambiguously, the word "system" means "burner control system" and "systems" means "burner control systems".
- for equipment that is used by the public, such as equipment intended to be used in shops, offices, hospitals, farms and commercial and industrial applications;
NOTE 2 Throughout this document, the word "equipment" means "appliance and equipment."
EXAMPLE 1 Controls for commercial catering, heating and air-conditioning equipment.
- that are smart enabled controls;
EXAMPLE 2 Remote interfaces/control of burner operations.
- that are AC or DC powered controls with a rated voltage not exceeding 690 V AC or 600 V DC;
- used in, on, or in association with equipment that use electricity, gas, oil, solid fuel, solar thermal energy, etc., or a combination thereof;
- utilized as part of a control system or controls which are mechanically integral with multifunctional controls having non-electrical outputs;
- using NTC or PTC thermistors and to discrete thermistors, requirements for which are contained in Annex J;
- that are mechanically or electrically operated, responsive to or controlling such characteristics as temperature, pressure, passage of time, humidity, light, electrostatic effects, flow, or liquid level, current, voltage, acceleration, or combinations thereof;
- as well as manual controls when such are electrically and/or mechanically integral with automatic controls.
NOTE 3 Requirements for manually actuated mechanical switches not forming part of an automatic control are contained in IEC 61058-1-1.
This document 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.
This document does not apply to thermoelectric flame supervision controls; thermoelectric flame supervision controls are covered by ISO 23551-6:2021.
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 series).
This document applies to controls powered by primary or secondary batteries, requirements for which are contained within the standard.
This document applies to
- the inherent safety of automatic electrical burner control systems, and
- functional safety of automatic electrical burner control systems,
- automatic electrical burner control systems where the performance (for example the effect of EMC phenomena) of the product can impair the overall safety and performance of the controlled system,
- the 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 4 Requirements for specific operating values, operating times and operating sequences are given in the standards for appliances and equipment.
This document specifies the requirements for construction, operation and testing of automatic electrical burner control systems used in, on, or in association with an equipment.
This document applies also to systems

IEC 60730-2-5:2013 applies to automatic electrical burner control systems for the automatic control of burners for oil, gas, coal or other combustibles for household and similar use including heating, air conditioning and similar use. This part 2-5 is applicable to a complete burner control system and to a separate programming unit. This part 2-5 is also applicable to a separate electronic high-voltage ignition source and to a separate flame detector. Separate ignition devices (electrodes, pilot burners, etc.) are not covered by this part 2-5 unless they are submitted as part of a burner control system. Requirements for separate ignition transformers are contained in IEC 60989. Systems utilizing thermoelectric flame supervision are not covered by this part 2-5. This part 2-5 applies to the inherent safety, to the manufacturer's 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. It was established on the basis of the fourth edition (2010) of that publication. Consideration may be given to future editions of, or amendments to, IEC 60730-1. The title of IEC 60730-2-5 Ed4.0 has been updated to the title of IEC 60730-1 Ed5.0. However, IEC 60730-2-5 Ed4.0 has not been updated in accordance with the technical requirements in IEC 60730-1 Ed5.0. This part 2-5 supplements or modifies the corresponding clauses in IEC 60730-1 so as to convert that publication into the IEC standard: Safety requirements for automatic electrical burner control systems. Key words: Automatic control, Burner control
This publication is to be read in conjunction with IEC 60730-1:2013.
