610100-000020-0001201 Scope and object
  This clause of Part 1 is applicable except as follows:
      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.    – The materials being treated in the intended application introduce significant heat 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.    – 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 can 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.    Addition:
    Add the following text after the last paragraph:
    NOTE 101 Examples of such equipment include environmental testing and plant growth 
TEST CHAMBERS
, refrigerating CIRCULATORS
 which incorporate heating, and recirculating coolers for extracting heat.    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 standard. 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 () for selection process and guidance in the Introduction.
    NOTE 102 Subclause 107 and Annex BB provide the definition and requirements for the protection of people who are inside 
WALK-IN EQUIPMENT
