45 FOREWORD
46 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
47 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
48 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
49 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
50 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
51 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
52 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
53 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
54 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
55 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
56 consensus of opinion on the relevant subjects since each technical committee has representation from all
57 interested IEC National Committees.
58 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
59 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
60 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
61 misinterpretation by any end user.
62 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
63 transparently to the maximum extent possible in their national and regional publications. Any divergence between
64 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
65 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
66 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
67 services carried out by independent certification bodies.
68 6) All users should ensure that they have the latest edition of this publication.
69 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
70 members of its technical committees and IEC National Committees for any personal injury, property damage or
71 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
72 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
73 Publications.
74 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
75 indispensable for the correct application of this publication.
76 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
77 rights. IEC shall not be held responsible for identifying any or all such patent rights.
78 International Standard IEC 60068-2-87 has been prepared by IEC technical committee TC 104

97 INTRODUCTION
98 UV-C radiation (100 nm to 280 nm) emitted by the Sun is known to destroy DNA and RNA in
99 living cells, but it is filtered entirely by the atmosphere so that none reaches the Earth’s surface.
100 Because of its effects on cells, artificial light sources that emit UV-C radiation are used to kill
101 or deactivate pathogens in air, water, and on material surfaces, a process known as ultra-violet
102 germicidal irradiation (UVGI). Although UVGI systems for disinfection of water have been in
103 use for decades, the technology’s use on surfaces and in air has become common more recently
104 and has accelerated in response to the COVID-19 pandemic.
106 UV-C radiation is potentially harmful to polymers, textiles, and other materials. Consequently,
107 UVGI treatments can degrade material properties, especially when frequently performed. The
108 test procedure set out in this document is intended as a standardized method of evaluating the
109 effects of UVGI on either samples of material or components, subsystems or complete systems
110 of electro-technical equipment.
112 The severities are listed in order from lowest to highest expected UV-C radiation dose. A low
113 severity environment represents materials exposed to UVGI treatments infrequently. Higher
114 severity environments represent materials with more frequent exposures, including materials
115 used within a UVGI system’s components.
117 The majority of UVGI systems in use rely on low pressure mercury lamps, which emit most of
118 their output at a single wavelength of 254 nm. This type of lamp is available in several power
119 levels and in many physical configurations, but the spectral output is the same regardless of
120 these factors. Other light sources are used in some UVGI systems, including excimer lamps
121 with output at 222 nm and LEDs with output at 265 nm. This document will be limited to
122 applications using low pressure mercury lamps because the technology is very well known and
123 commercial testing using it is available.
