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 NOTE Throughout this standard the word "equipment" means "appliance and equipment." This 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. Throughout this standard, 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 standard. This standard also applies to electrical burner control systems intended exclusively for industrial process applications e.g. those applications covered by ISO TC 244 (ISO 13577).
