prEN IEC 61010-2-011:2025

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 SYSTEMSas an integral part of, or separate from, the equipment and the equipment is in direct control of the REFRIGERATING
SYSTEM. It also details the requirements for STIRLING REFRIGERATION SYSTEMS.
Equipment within the scope of this document employ risk mitigations for the following constructions: CO2 systems, non-flammable refrigerant systems, flammable refrigerant
systems with less than 150g and flammable refrigerants less than 13 LFL.
Addition:
dd) This document addresses all refrigeration systems and their associated components and
piping using gaseous or liquid refrigerant or mixtures of refrigerants given in ISO 817.
Pressure equipment, assemblies and their components below or equal to the limits set out in points (A) for vessels and (B) for piping respectively shall be designed and manufactured in accordance with the sound engineering practice in this document.
Fluids with hazard statement H220 and H221 are considered group 1 fluids, where the maximum allowable temperature is above the flashpoint, and substances and mixtures with a
maximum allowable temperature TS which exceeds the flashpoint of the fluid.
Fluids contained in group 2 (“non-dangerous fluids”) are fluids with no risk or other risks not quoted above associated with them.
A detailed list of can be found in Annex GG of this document.
A) Limits for vessels
This covers gases, liquefied gases, gases dissolved under pressure, vapours and those liquids whose vapour pressure at the maximum allowable temperature is > 0,5 bar above normal atmospheric pressure (1 013 mbar) within the limits detailed in Table CC.1 of Annex CC of this document.
B) Limits for piping
This covers liquids having a vapour pressure at the maximum allowable temperature of ≤ 0,5 bar above normal atmospheric pressure (1 013 mbar) within the limitsdetailed in Table CC.2
of Annex CC of this document.
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 61010:2020 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.
