This clause of part 1 is applicable except as follows: 1.1 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 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. Throughout this part 2-5, where it can be used unambiguously, the word "system" means "burner control system" and "systems" means "burner control systems". Systems utilizing thermoelectric flame supervision are not covered by this part 2-5. 1.1.1 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. Requirements for specific operating values, operating times and operating sequences are given in the standards for appliances and equipment. Systems for equipment not intended for normal household use, but which nevertheless may be used by the public, such as equipment intended to be used by laymen in shops, in light industry and on farms, are within the scope of this part 2-5. This part 2-5 applies to systems using NTC or PTC thermistors, additional requirements for which are contained in annex J. EN 60730-2-1 is not applicable to burner control systems. Page 5 EN 60730-2-5:2002  ‚This part 2-5 does not apply to systems designed exclusively for industrial applications. 1.1.2 This part 2-5 applies to manual controls when such are electrically and/or mechanically integral with automatic controls. Requirements for manual switches not forming part of an automatic control are contained in IEC 61058-1. Throughout this part 2-5, the word "equipment" means "appliance and equipment". 1.2 Replacement: This part 2-5 applies to systems with a rated voltage not exceeding 660 V and with a rated current not exceeding 63 A. 1.3 Replacement: This part 2-5 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 household equipment standard or as determined by the manufacturer applies. This part 2-5 includes systems responsive to flame properties. 1.4 Replacement: This part 2-5 applies also to systems incorporating electronic devices, requirements for which are contained in annex H.
