Foreword
This document was drafted as per the rules specified in GB/T 1.1-2020 Directives for
Standardization – Part 1: Rules for the Structure and Drafting of Standardizing Documents.
This Document is Part 2 of GB/T 16422 Plastics – Methods of Exposure to Laboratory Light
Sources. GB/T 16422 has published the following parts:
--- Part 1: General Guidance;
--- Part 2: Xenon-Arc Sources;
--- Part 3: Fluorescent UV Lamps;
--- Part 4: Open Flame Carbon Arc Lamp.
This Document replaced GB/T 16422.2-2014 Plastics – Methods of Exposure to Laboratory
Light Sources – Part 2: Xenon-Arc Sources. Compared with GB/T 16422.2-2014, the major
technical changes of this Document are as follows besides the structural adjustments and
editorial modifications:
a) Add the statement about spectral irradiance "2nm incremental measurement" in footnote
a of "Table 1" and footnote a of "Table 2" (see Tables 1 and 2 of this Edition);
b) Add suggestions for measuring the maximum surface temperature device (see 5.4 of this
Edition);
c) Change the exposure cycle in Table 3; only retain the original three exposure cycles;
delete two exposure cycles with a black standard temperature of (100±3) °C in Method
A (see Table 3 of this Edition; Table 3 of 2014 Edition); and adjust the other three
exposure cycles that do not control the temperature and relative humidity of the test
chamber to Table B.1 (see Table B.1 of this Edition; Table 3 of 2014 Edition);
d) Change the exposure cycle in Table 4; only retain the original three exposure cycles;
delete the two exposure cycles with black panel temperature of (89±3) °C in Method A
(see Table 4 of this Edition; Table 4 of 2014 Edition); and adjust the other three exposure
cycles that do not control the temperature and relative humidity of the test chamber and
add the exposure cycles of the two Methods A to Table B.2 (see Table B.2 of this Edition;
Table 4 of 2014 Edition);
e) Change the provisions on the setting of exposure conditions; and point out that there is
no correlation between the black standard temperature and the black panel temperature
and the conditions for the use of the black standard thermometer instead of the black
panel thermometer (see 7.6 of this Edition; 6.6 of 2014 Edition);
f) Add the Annex "More Exposure Cycles" (see Annex B of this Edition).
This Document equivalently adopts ISO 4892-2:2013 Plastics – Methods of Exposure to
Laboratory Light Sources – Part 2: Xenon-Arc Lamps.
This Document adds a Clause of “Terms and Definitions”.
This Document made the minimum editorial modifications:
--- Incorporate the amendments of ISO 4892-2:2013/Amd.1:2021, and the outer margins of
the terms involved are marked with vertical double lines (‖).
Please note some contents of this Document may involve patents. The issuing agency of this
Document shall not assume the responsibility to identify these patents.
This Document was proposed by China Petroleum and Chemical Industry Federation.
This Document shall be under the jurisdiction of National Technical Committee on Plastics of

Plastics – Methods of Exposure to Laboratory Light Sources
– Part 2: Xenon-Arc Lamps
1 Scope
This Document specifies the test method for the exposure of specimens in the test equipment
equipped with xenon arc lamp, heat and humidity. The test equipment simulates the actual use
environment of total solar radiation or solar radiation through window glass, so that the material
produces effects similar to natural aging.
This Document is applicable to laboratory artificial accelerated weathering tests of plastic
specimens exposed to filtered xenon arc lamps under controlled environmental conditions
(temperature, humidity and/or wetting). Different test requirements can be met by combining
different types of xenon arc lamps and filters.
Specimen preparation and result evaluation for specific materials refer to other standards.
ISO 4892-1 gives the general guidance of this Document.
NOTE: Refer to GB/T1865-2009 for the xenon arc lamp exposure test method for paints and varnishes.
