UL Standard | UL 372
ulharm-372.6
This standard modifies or amends the requirements of the Part 1 standard. In Canada the Part 1 standard applicable is CAN/CSA E60730-1, Automatic electrical controls for household and similar use - Part 1: General Requirements, and in the U.S. the Part 1 standard applicable is UL 60730-1A, Automatic electrical controls for household and similar use - Part 1: General Requirements, 3rd Edition.This standard applies to newly produced automatic burner ignition systems and system components constructed entirely of new, unused parts and materials for the automatic control of burners for one or more of the following fuels:
Components can be, but are not limited to: automatic controls; pilot burners, thermoelectric devices, electrodes, ignition devices, ignition sources and flame detectors.Throughout this standard the following terms shall be abbreviated as shown below:
This standard applies to 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 systems and components 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.
1.1.2 Replacement:This standard applies to manual controls when such are electrically and/or mechanically integral with automatic systems.
This standard applies to each component of an automatic burner ignition system shall be capable of operation throughout an ambient temperature range of 32�F (0�C) to 125�F (51.5�C). The manufacturer is allowed to specify temperatures below 32�F (0�C) and above 125�F (51.5�C).
b) For burner controls for all other equipment, Tmax, declared at less than 150�F (65.5�C) shall be tested at 150�F (65.5�C) or higher as specified by the manufacturer.
1.4 Replacement:This standard applies also to controls incorporating electronic devices, requirements for which are contained in annex h, Requirements for electronic systems and components.

Summary of Topics s0372_6_sum.html
This revision of UL 372 is being issued to remove the ANSI approval. No changes in requirements are involved. As noted in the Commitment for Amendments statement located on the back side of the title page, UL, CSA, and CSA America are committed to updating this harmonized standard jointly. However, the revision pages dated July 27, 2012 will not be jointly issued by UL, CSA, and CSA America, as these revision pages only address the removal of the ANSI approval from UL 372.
