CAN/CSA-E730-2-5-94 (R2013)

This National Standard of Canada is based on International Standard CEI/IEC 730-2-5:1990 (first edition). 1. Scope This clause of Part 1 is replaced as follows: 1.1 This standard 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. Burner control systems utilizing thermoelectric flame supervision are not covered by this standard. 1.1.1 This standard applies to the inherent safety, to the manufacturer's declared operating values, operating times and operating sequences where such are associated with the 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. Automatic electrical controls 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 standard. This standard does not apply to automatic electrical controls designed exclusively for industrial applications. 1.1.2 This standard applies to manual controls when such are electrically and/or mechanically integral with automatic controls. It also applies to controls incorporating electronic parts. Requirements for manual switches not forming part of an automatic control are contained in IEC Publication 328. Separate ignition transformers are not covered by this standard (in the scope of SC 14D). Throughout this standard, the word "equipment" means "appliance and equipment". 1.2 This standard applies to controls with a rated voltage not exceeding 660 V and with a rated current not exceeding 63 A. 1.3 This standard 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 shall apply. This standard includes controls responsive to flame properties.
