Description
1 Scope and object
This clause of Part 1 is applicable, except as follows:
1.1.1 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.
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 (Figure 102) for the selection process and guidance
in the Introduction.
1.1.2 Equipment excluded from scope
Addition:
Add the following new item after item j):
or equipment incorporating:
aa) a transcritical REFRIGERANT SYSTEM (system that uses CO2) or a system that uses
ammonia (NH3) as the REFRIGERANT.
1.2 Object
1.2.1 Aspects included in scope
Replacement:
Replace the first paragraph by the following:
The object of this document is to ensure that the design and methods of construction of
REFRIGERATING EQUIPMENT provide adequate protection for OPERATORS, bystanders, trained
service personnel, and the surrounding area against the specific HAZARDS that relate to
REFRIGERATING SYSTEMS.
Addition:
Add the following note after the existing note:
NOTE 101 A list of HAZARDS typically associated with REFRIGERATING SYSTEMS and REFRIGERANTS is included in
Annex BB.
