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. NOTE1 Throughout this document, where it can be used unambiguously, the word \'system\' means \'burner control system\' and \'systems\' means \'burner control systems\'. NOTE2 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 ISO23551‑6 . This document also applies to electrical burner control systems intended exclusively for industrial process applications e.g. those applications covered by ISO TC 244 ( ISO13577 ). 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 660V AC or 600V 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 AnnexH. 1.1.5 This document applies to system s using NTC or PTC thermistors, additional requirements for which are contained in AnnexJ. 1.1.6 This document includes systems responsive to flame properties and temperature for HTO.
