Foreword
GB/T 16422 Plastics – Methods of Exposure to Laboratory Light Source can be divided into
the following four parts:
--- Part 1: General Guidance;
--- Part 2: Xenon-Arc Lamps;
--- Part 3: Fluorescent UV Lamps;
--- Part 4: Open Flame Carbon Arc Lamp.
This Part is Part 1 of GB/T 16422.
This Part was drafted as per the rules specified in GB/T 1.1-2009.
This Part replaced GB/T 16422.1-2006 Plastics – Methods of the Exposure to Laboratory Light
Source – Part 1: General Guidance. Compared with GB/T 16422.1-2006, the major technical
changes of this Part are as follows:
--- Modify the content of the Clause "Scope" (see Clause 1 of this Edition; Clause 1 of 2006
Edition);
--- Modify the content of the Clause "Normative References"; and revise the references to
undated references (see Clause 2 of this Edition; Clause 2 of 2006 Edition);
--- Add relevant terms (see 3.3 and 3.4 in Clause 3 of this Edition);
--- Modify the content of the Clause "Principles" (see Clause 4 of this Edition; Clause 4 of
2006 Edition);
--- Modify the content of the Clause "Requirements for Laboratory Exposure Equipment"
(see Clause 5 of this Edition; Clause 5 of 2006 Edition);
--- Modify the content of the Clause "Specimen" (see Clause 6 of this Edition; Clause 6 of
2006 Edition);
--- Modify the content of the Clause "Test Conditions and Procedures" (see Clause 7 of this
Edition; Clause 7 of 2006 Edition);
---Modify the content of the Clause "Precision and Bias" (see Clause 8 of this Edition;
Clause 8 of 2006 Edition);
--- Adjust Annex B of the 2006 edition into Annex C, and modify relevant content (see
Annex C of this Edition; Annex B of 2006 Edition).
This part used the translation method to equivalently adopt ISO 4892-1:2016 Plastics –
Methods of Exposure to Laboratory Light Sources – Part 1: General Guidance.
The Chinese documents that have consistent correspondence with the international documents
cited in this Part are as follows:
--- GB/T 2918-2018 Plastics - Standard Atmospheres for Conditioning and Testing (ISO
291:2008, MOD);

3: Fluorescent UV Lamps (ISO 4892-3:2006, IDT);
--- GB/T 16422.4-2014 Plastics - Methods of Exposure to Laboratory Light Sources - Part
4: Open-Flame Carbon-Arc Lamps (ISO 4892-4:2004, IDT).
This Part was proposed by China Petroleum and Chemical Industry Federation.
This Part shall be under the jurisdiction of National Technical Committee on Plastics of
Standardization Administration of China (SAC/TC 15).

Plastics – Methods of Exposure to
Laboratory Light Sources – Part 1: General Guidance
1 Scope
This Part of GB/T 16422 provides information and general guidance relevant to the selection
and operation of the methods of exposure described in detail in subsequent parts. It also
describes 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.
NOTE: In this Part, the term “light source” refers to radiation sources that emit UV radiation, visible
radiation, infrared radiation or any combination of these types of radiation.
This Part 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 given in ISO 4582.
