52 Part 4-2: Assessment of the environmental impact of battery failure
53 in an electrochemical based storage system
55 FOREWORD
56 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization
57 comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to
58 promote international co-operation on all questions concerning standardization in the electrical and
59 electronic fields. To this end and in addition to other activities, IEC publishes International Standards,
60 Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides
61 (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees;
62 any IEC National Committee interested in the subject dealt with can participate in this preparatory work.
63 International, governmental and non-governmental organizations liaising with the IEC also participate
64 in this preparation. IEC collaborates closely with the International Organization for Standardization
65 (ISO) in accordance with conditions determined by agreement between the two organizations.
66 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an
67 international consensus of opinion on the relevant subjects since each technical committee has
68 representation from all interested IEC National Committees.
69 3) IEC Publications have the form of recommendations for international use and are accepted by IEC
70 National Committees in that sense. While all reasonable efforts are made to ensure that the technical
71 content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are
72 used or for any misinterpretation by any end user.
73 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC
74 Publications transparently to the maximum extent possible in their national and regional publications.
75 Any divergence between any IEC Publication and the corresponding national or regional publication
76 shall be clearly indicated in the latter.
77 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide
78 conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not
79 responsible for any services carried out by independent certification bodies.
80 6) All users should ensure that they have the latest edition of this publication.
81 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts
82 and members of its technical committees and IEC National Committees for any personal injury, property
83 damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including
84 legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or
85 any other IEC Publications.
86 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced
87 publications is indispensable for the correct application of this publication.
88 9) Attention is drawn to the possibility that some of the elements of this IEC Publication can be the subject
89 of patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
90 IEC 62933-4-2 has been prepared by IEC technical committee 120: Electrical
91 Energy Storage (EES) Systems. It is an International Standard.
92 The text of this International Standard is based on the following documents:

110 ELECTRICAL ENERGY STORAGE (EES) SYSTEMS –
112 Part 4-2: Assessment of the environmental impact of battery failure
113 in an electrochemical based storage system
114 1 Scope
115 This part of IEC 62933 defines the requirements for evaluating and reporting of the
116 negative impact on the environment caused by the failure of a cell, flow cell, battery
117 or flow battery in the accumulation subsystem of the battery energy storage system
118 (BESS).
119 The mainstream batteries currently used in BESS are classified in this document
120 according to the type of their electrolyte. These electrolyte types are aqueous, non-
121 aqueous or solid.
122 In flow batteries, the aqueous electrolyte contains additionally the dissolved
123 electrochemically active species and recirculates from external storage volumes
124 through the flow cells.
125 The environmental impacts directly caused by the failure of other components of
126 the BESS are not within the scope of this standard.
127 IEC TS 62933-4-1 outlines notions concerning environmental issues pertaining to
128 electrical energy storage systems. These notions relate to product life cycle, system
129 aspects and the nature of electrical energy storage technology.
