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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 877-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 6, Ageing, chemical
and environmental resistance.
Together with the other parts (see below), it cancels and replaces ISO 877:1994, which has been technically
revised.
ISO 877 consists of the following parts, under the general title Plastics — Methods of exposure to solar
radiation:
⎯ Part 1: General guidance
⎯ Part 2: Direct weathering and exposure behind window glass
⎯ Part 3: Intensified weathering using concentrated solar radiation

ISO 877-1:2009(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 877-2:2009, method A) or to
indirect weathering using glass-filtered solar radiation (ISO 877-2:2009, 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
tropical regions, where the sun is most powerful at high zenith angles.
Polar-facing surfaces are much less likely to be degraded than equator-facing surfaces because they are less
exposed to solar radiation. However, the fact that they may remain wet for longer periods may be of
significance for materials affected by moisture or for materials that are susceptible to microbial growth.
