56 FOREWORD
57 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
58 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
59 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
60 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
61 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC
62 Publication(s)"). Their preparation is entrusted to technical committees; any IEC National Committee interested
63 in the subject dealt with may participate in this preparatory work. International, governmental and non-
64 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
65 with the International Organization for Standardization (ISO) in accordance with conditions determined by
66 agreement between the two organizations.
67 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
68 consensus of opinion on the relevant subjects since each technical committee has representation from all
69 interested IEC National Committees.
70 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
71 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
72 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
73 misinterpretation by any end user.
74 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
75 transparently to the maximum extent possible in their national and regional publications. Any divergence
76 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
77 the latter.
78 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
79 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
80 services carried out by independent certification bodies.
81 6) All users should ensure that they have the latest edition of this publication.
82 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
83 members of its technical committees and IEC National Committees for any personal injury, property damage or
84 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
85 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
86 Publications.
87 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
88 indispensable for the correct application of this publication.
89 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
90 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
91 International Standard IEC 61010-2-011 has been prepared by IEC technical committee 66:
92 Safety of measuring, control and laboratory equipment.
93 It has the status of a group safety publication in accordance with IEC Guide 104.
94 This third edition cancels and replaces the second edition published in 2019. This edition
95 constitutes atechnical revision.
96 This edition includes the following significant changes from the second edition, as well as
97 numerous other changes.
98 a) adjustment of the scope to include CO2 refrigeration systems including a TRANSCRITICAL
99 REFRIGERATION SYSTEM and the ancillary components and requirements that such a system
100 requires
IEC CDV 61010-2-011 © IEC 2025
101 b) addition of the supplemental requirements if the flammable charge exceeds 150g per
102 stage to a maximum of 13 times the LFL of the flammable refrigerant per stage but still
103 relying on risk mitigation if a leak occurs under single fault conditions.
104 c) addresses the use of other equipment inside the refrigerated compartment.
105 d) updated marking and documentation requirements.
106 e) addition of requirements to prevent back-siphonage into potable water systems for water
107 cooled systems.
108 f) updated requirements for piping joints and fittings (clause 8.1.102).
109 g) Additional requirements for the protection against cold surfaces (clause 10.1.101).
110 h) Update to the requirements for fluidic pressure requirements for an R744 (CO ) system
111 (11.7.101 to 11.7.105.4.4)
112 i) an update to the protective requirements for pressures caused by transport and storage
113 temperatures.
114 j) An update of material requirements for components using for REFRIGERATING
115 SYSTEMS(14.102)
116 k) Update of Annex CC for thesafety requirements of components and piping
117 l) Addition of Annex EE for determining the gas concentration beyond the boundary in a
118 system using a FLAMMABLE REFRIGERANT charge greater than 150g per stage.
119 m) Addition of Annex GG to provide an informative reference for the Globally Harmonized
120 System of Classification and Labelling of Chemicals with respect to refrigerants.
121 n) Update requirements to address the requirements for Stirling Refrigeration Systems
