UNE-EN 61010-2-012:2016

This clause of Part 1 is applicable except as follows:

1.1.1Equipment included in scope

Replacement: Replace the first paragraph by the following:

This Part 2 of IEC 61010 specifies safety requirements for electrical equipment and their accessories within the categories a) through c) 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 cooling system generates additional and/or more severe HAZARDS than those for the two systems if treated separately.

The materials being treated in the intended application introduce significant heat into the REFRIGERATING SYSTEM that the cooling system in the application yield additional and/or more severe HAZARDS than those for the cooling system if operated at the maximum RATED ambient alone.

An irradiation function for the materials being treated presenting additional HAZARDS.

A function to expose the materials being treated to excessive humidity, carbon dioxide, salt mist, or other substances which may result in additional HAZARDS.

A function of MECHANICAL MOVEMENT presenting additional HAZARDS.

Provision for an OPERATOR to walk-in to the operating area to load or unload the materials being treated.

Categories of equipment:

Addition:

Add the following new notes and paragraph after the last paragraph:

NOTE 101 Examples of such equipment include environmental testing and plant growth TEST CHAMBERS, refrigerating CIRCULATORS which incorporate heating, recirculating coolers for extracting heat.

If 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 standard, it shall also meet the requirements of those other Part 2 standards. However, when the equipment incorporates only a REFRIGERATING SYSTEM or only a heating function or a combination of the two without introducing additional HAZARDS described in the above dashed paragraphs then the application of IEC 61010-2-011 or IEC 61010-2-010 or both, as applicable, shall be considered instead of this Part 2.

See further information in the flow chart for selection process and guidance in the INTRODUCTION.
