FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 60068-2-87 has been prepared by IEC technical committee 104: Environmental conditions,
classification and methods of test. It is an International Standard.
The text of this International Standard is based on the following documents:

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

ENVIRONMENTAL TESTING –
Part 2-87: Tests – UV-C exposure of materials and components to
simulate ultraviolet germicidal irradiation or other applications

1 Scope
This part of IEC 60068 describes exposures of materials and components to UV-C radiation
during ultraviolet germicidal irradiation (UVGI) treatments or other processes that require UV-C
exposure and test procedures to simulate those environments. Severities representing various
frequencies and intensities of UV-C exposures are described. Test conditions are described
and limited to devices that utilize low pressure mercury lamps which emit most of their radiation
at a single spectral line at 254 nm.
NOTE A more precise characterization of the wavelength of the spectral line is 253,7 nm. The ability for a laboratory
to determine the wavelength to this resolution is rare. Therefore, this spectral line is often quantified to the resolution
of 1 nm.
