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 document 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
constitute an endorsement.

Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by the International Commission on Illumination (CIE) Technical Committee
6-32, Action Spectrum for Photocarcinogenesis, in cooperation with Technical Committee ISO/TC 274, Light
and lighting.
This third edition cancels and replaces the second edition (ISO/CIE 28077:2016), which has been technically
revised.
The main changes are as follows:
— text giving historical background shifted to Annex A;
— Normative reference updated;
— Bibliography updated;
— minor editorial changes.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
Solar ultraviolet radiation (UVR) is recognized as a major cause of non-melanoma skin cancer in humans.
Skin cancer occurs most frequently in the areas of the body most exposed to solar radiation, and correlates
with the duration and intensity of outdoor exposure to UVR. Describing the relationship of exposure
(dose) to risk (skin cancer) requires the availability of a spectral weighting function or action spectrum
for photocarcinogenesis. This document proposes the adoption of an action spectrum derived from
experimental laboratory data and modified to estimate the non-melanoma tumour response in human skin.
The experimental data are not sufficient for specifying effectiveness above 400 nm, but are sufficient for
estimating effectiveness from 400 nm down to 250 nm.

4 Action spectrum for photocarcinogenesis of non-melanoma skin cancers
The action spectrum for photocarcinogenesis is based principally on experimental data from mice because
comparable data are not available from humans. The limits of this extrapolation are yet to be determined.
Based on all these considerations, a standard action spectrum for photocarcinogenesis is provided in Table 1
and shown in Figure 1.
Some historic background information on the development of the photocarcinogenesis action spectrum is
given in Annex A.
