1 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.

NOTE 102 Subclause 107 and Annex BB provide the definition and requirements for the protection of people who are inside
