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).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

ISO/DIS 877-1:2016(E)
Introduction
Outdoor-exposure tests of the type specified in the three parts of this International Standard are
needed to evaluate the performance of plastics when exposed to solar radiation. The results of such tests
should be regarded only as an indication of the effect of exposure to direct weathering (ISO/DIS 877-
2:2016, method A) or to indirect weathering using glass-filtered solar radiation (ISO/DIS 877-2:2016,
method B) or to intensified solar radiation (ISO 877-3) by the methods described. Results from tests
conducted in accordance with any of the parts of this International Standard will show some variability
when comparing results from repeat exposures conducted at the same location at a different time. This
is much more important for materials that show significant change after a year or less of exposure. In
general, results from repeat exposures at the same location are necessary to determine the range of
performance of a material subjected to exposure to solar radiation as specified in this International
Standard. Since the type of climate can have a significant effect on the rate and type of degradation,
results from exposures conducted in different types of climate are necessary to fully characterize
the outdoor durability of a material. For solar-concentrating exposures conducted in accordance with
ISO 877-3, exposure duration is defined in terms of the total solar UV radiant exposure because of the
annual and seasonal variations in solar ultraviolet radiation.
Fresnel-reflecting concentrators of the type described in ISO 877-3, which employ solar radiation as the
source of ultraviolet radiation, are utilized to provide accelerated outdoor-exposure testing of many
plastics materials.
A system of classifying and characterizing climates in different parts of the world is given in Annex A.
The test method chosen is usually that designed to expose the material to the most severe conditions
associated with any particular climate. It should, therefore, be borne in mind that the severity
of exposure in actual use is, in most cases, likely to be less than that specified in this International
Standard, and allowance should be made accordingly when interpreting the results. For example,
vertical exposure at 90° from the horizontal is considerably less severe in its effects on plastics than
near-horizontal exposure, particularly in
