Plastics - Methods of exposure to laboratory light sources - Part 1: General guidance and requirements (ISO 4892-1:2024)
This document provides general guidance and requirements relevant to the selection and operation of the methods of exposure described in detail in subsequent parts of the ISO 4892 series. It also specifies general performance requirements for devices used for exposing plastics to laboratory light sources. Information regarding performance requirements is for producers of artificial accelerated weathering or artificial accelerated irradiation devices.
This document also provides information on the interpretation of data from artificial accelerated weathering or artificial accelerated irradiation exposures. More specific information about methods for determining the change in the properties of plastics after exposure and reporting these results is not part of this document.

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.

This document was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 6,
Ageing, chemical and environmental resistance, in collaboration with the European Committee for
Standardization (CEN) Technical Committee CEN/TC 249, Plastics, in accordance with the Agreement
on technical cooperation between ISO and CEN (Vienna Agreement).
This fourth edition cancels and replaces the third edition (ISO 4892-1:2016), which has been technically
revised.
The main changes are as follows:
— definition of 3.2 and 3.5 clarified and Notes to entry added;
— definition and Notes to entry of 3.3 and 3.4 clarified;
— new terms and definitions and Notes to entry added for black-panel thermometer, black-standard
thermometer, white-panel thermometer, and white-standard thermometer (3.7 – 3.10);
— reference to ISO/TR 18486 added under 4.2.4;
— calibration requirements clarified in 5.1.7, 5.2.8, 5.2.9, 5.3.6;
— requirements regarding black-panel thermometer, black-standard thermometer, white-panel
thermometer, and white-standard thermometer in 5.2 and Table 2 clarified;
— reference to ISO 23741 added in 5.3.1;
— new Subclause 7.3 “Sampling for intermediate and final evaluation” added;

Introduction
Plastics are often used outdoors or in indoor locations where they are exposed to solar radiation or to
solar radiation behind glass for long periods. It is therefore very important to determine the effects of
solar radiation, heat, moisture and ot
