610100-000020-0001101 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 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.
Modification of Clause 1.1.1 to add the following after the second paragraph: 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. See further information in the flow chart () for the selection process and guidance in the Introduction.
