IEC 60730-2-9:2015 PDF Download

The automatic electrical temperature sensing controls used in various equipment, such as heating, air conditioning, and other related applications, are covered by the IEC 60730-2-9:2015 standard. These controls can be utilized in a variety of machinery that runs on various fuels, including electricity, gas, oil, etc. The standard also covers temperature sensor controls used in public spaces including stores, offices, hospitals, farms, and other commercial or industrial settings as well as those used in building automation control systems.

It is significant to note that, unless particularly indicated in pertinent equipment standards, this standard does not cover temperature sensor controls created solely for industrial process applications. The standard is focused on the equipment's intrinsic safety, operating values, operating times, and operating sequences. It also offers instructions for evaluating automatic electrical temperature sensor controllers connected to or used with equipment.

The functional safety of low-complexity safety-related temperature sensing controls and systems is also covered by the IEC 60730-2-9:2015 standard. The third version from 2008 and its 2011 update have been superseded by this fourth edition. Technical updates have been made to the current edition, such as adjustments to heating-freezing tests, alignment of the EMC criteria with other Part 2 standards, and the inclusion of requirements for the class B and class C control functions of temperature sensor controllers in a separate clause.

It is advised to consult IEC 60730-1:2013 in conjunction with this standard to fully comprehend the prerequisites and recommendations.
