scope:

1 Scope and object

This clause of Part 1 is applicable, except as follows:

Replacement:

Replace the second paragraph by the following:

This Part 2 of IEC 61010 specifies particular safety requirements for the following types a) to c) of electrical equipment and their accessories, wherever they are intended to be used, whenever that equipment incorporates

REFRIGERATING SYSTEMS

as an integral part of, or separate from, the equipment and the equipment is in direct control of the

REFRIGERATING SYSTEM

.

This document details all the requirements when up to 150 g of

FLAMMABLE REFRIGERANT

are used per stage of a

REFRIGERATING SYSTEM

. Additional requirements beyond the current scope of this document apply if a

REFRIGERANT

charge of

FLAMMABLE REFRIGERANT

exceeds this amount.

For

REFRIGERATION SYSTEM

with more than 150 g per stage, the requirement of UL 60335-2-89 shall be used. Transcritical

REFRIGERATION SYSTEMS

and systems that use ammonia (NH3) as the

REFRIGERANT

shall be evaluated to the requirements of UL 60335-2-89.

Addition:

Add the following text after the last paragraph:

NOTE 101 Examples for

REFRIGERATING EQUIPMENT

include, but are not limited to, laboratory equipment such as laboratory refrigerators, freezers, refrigerated display cabinets.

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 will also apply. In particular, if equipment is intended to be used as a centrifuge, the requirements of IEC 61010-2-020 apply. However, when the equipment incorporates a refrigerating system and a heating function where the combination of the two introduces additional or more severe

HAZARDS

than if treated separately, then it is possible that IEC 61010-2-012 is applicable instead of this Part 2-011.
