Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO 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, ISO 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 www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.
Any trade name used in this document is information given for the convenience of users and does not

This document was prepared by Technical Committee ISO/TC 142 Cleaning equipment for air and other
gases.
This second edition cancels and replaces the first edition (ISO 15858:2016), which has been technically
revised.
The main changes are as follows:
— eexpansion to include all ultraviolet-C wavelengths between 180 nm and 280 nm introduction has
been added;
— measurement procedure has been added;
— table of spectral weighting function S(λ) from 180 nm to 280 nm has been added;
— informative Annex A has been added;
— partial content of the sources of UV-C exposure has been removed.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.

Introduction
The document ISO 15858:2016 was developed to specify an in-situ safety assessment method for
applications with UV-C disinfection systems and devices focusing on 254 nm radiation. This new edition
of ISO 15858 expands the applicability of this document to the UV-C wavelength range from 180 nm to
280 nm to take newly developed technologies in the spectral range below 240 nm into account and
offers an improved description of the scope, limits, assessment method and assessment report.

1 Scope
This document specifies an in-situ optical radiation safety assessment method for applications with
UV-C disinfection systems and devices with a wavelength between 180 nm and 280 nm.
This document is applicable to the application of (partly) open in-duct UV-C systems, upper-air in room
UV-C systems, portable in-room disinfection UV-C devices, and any other device which can expose
humans to UV-C radiation.
This document is not applicable to fully closed UV-C devices, UV-C systems used in controlled access
locations and UV-C devices used for water disinfection.
