prEN IEC 61010-2-012:2025

This clause of Part 1 is applicable except as follows:
1.1.1 Equipment included in scope
Replacement:
Replace the second paragraph by the following:
This part of IEC 61010 specifies safety requirements for electrical equipment and its accessories within the categories a) through c), wherever it is intended to be used, whenever
that equipment incorporates one or more of the following characteristics:
– A REFRIGERATING SYSTEM that is acted on or impacted by an integral heating function such that the combined heating and REFRIGERATING SYSTEM generates additional and/or more severe HAZARDS than those for the two systems if treated separately, and
when containing or intended for use with hazardous fluids, whether flammable or under high pressure, such that additional and/or more severe HAZARDS resulted than those for non-hazardous fluids.
– The materials being treated in the intended application introduce significant heat (CONTROLLED TEMPERATURE) into the REFRIGERATING SYSTEM, so that the REFRIGERATING SYSTEM in the application yields additional and/or more severe HAZARDS than those for the REFRIGERATING SYSTEM if operated at the maximum RATED
ambient temperature alone.
This document details the requirements for equipment with fluidic pressure systems when containing or intended for use with a) non-flammable REFRIGERANTS of no charge limit including R-744 (CO2), in either subcritical and transcritical state, and b) FLAMMABLE REFRIGERANT where a single rupture of the REFRIGERANT CIRCUIT may result in full or part of the REFRIGERANT CHARGE releasable to an OCCUPIED SPACE, with limited MAXIMUM REFRIGERANT CHARGE mc, or RELEASABLE REFRIGERANT CHARGE mrl up to 13×LFL, and c) FLAMMABLE REFRIGERANT where a single rupture of the REFRIGERANT CIRCUIT does not
result in a REFRIGERANT release to an OCCUPIED SPACE, for example, in case of a liquid to liquid heat pumps, liquid to gas heat pumps, and cooling and/or heating CIRCULATORS, MAXIMUM REFRIGERANT CHARGE or MINIMUM FLOOR AREA is not required.
Addition:
Add the following text after the last paragraph:
NOTE 101 Examples of such equipment include, refrigerated and heating TEST CHAMBERS, CIRCULATORS with integrated heating, and recirculating coolers / chillers for extracting heat from above maximum ambient temperatures.
NOTE 102 National and regional laws and regulations may apply, Examples include but are not limited to Pressure
Equipment Directive PED 2014/68/EU, Boiler and Pressure Vessel Code, BPVC of ASME, USA, etc.
It is possible that all or part of the equipment falls within the scope of one or more other Part 2 standards of IEC 61010 as well as within the scope of this document. In that case, the requirements of those other Part 2 standards also apply. This document is intended for application when one or more of the additional HAZARDS described in the above dashed listed items are introduced. However, when the equipment incorporates only a REFRIGERATING SYSTEM or only a heating function or a combination of the two without introducing the
additional HAZARDS described in the above list, then IEC 61010-2-011 or IEC 61010-2-010 or both, as appropriate, apply instead of this Part 2-012.
See further information in the flow chart (Figure 102) for selection process and guidance in the Introduction.
NOTE 103 Term item 3.1.107 and Annex BB provide the definition and requirements for the protection of people who are inside WALK-IN EQUIPMENT.
