ISO 4892-1:2016 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 of ISO 4892, the term "light source" refers to radiation sources that emit UV radiation, visible radiation, infrared radiation or any combination of these types of radiation.

ISO 4892-1:2016 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.

3 Terms and definitions

For the purposes of this document, the following terms and definitions apply.

NOTE Definitions of other terms that are related to weathering tests are found in Reference [2].

3.1control

material which is of similar composition and construction to the test material and which is exposed at the same time for comparison with the test material

Note 1 to entry: An example of the use of a control material would be when a formulation different from one currently being used is being evaluated. In that case, the control would be the plastic made with the original formulation.

3.2file specimen

portion of the material to be tested which is stored under conditions in which it is stable and which is used for comparison between the exposed and unexposed states

3.3artificial accelerated weathering

exposure of a material in a laboratory weathering device to conditions which may be cyclic and intensified compared with those encountered in outdoor or in-service exposure

Note 1 to entry: This involves a laboratory radiation source, heat and moisture (in the form of relative humidity and/or water spray, condensation or immersion) in an attempt to produce more rapidly the same changes that occur in outdoor exposure.

Note 2 to entry: The device may include means for control and/or monitoring of the light source and other weathering parameters. It may also include exposure to special conditions, such as acid spray to simulate the effect of industrial gases.

3.4artificial accelerated irradiation

exposure of a material to a laboratory radiation source intended to simulate window-glass-filtered solar radiation or radiation from interior lighting sources and where specimens may be subjected to relatively small changes in temperature and relative humidity in an attempt to produce more rapidly the same changes that occur when the material is used in an indoor environment

Note 1 to entry: These exposures are commonly referred to as fading or lightfastness tests.

3.5reference material

material of known performance

3.6reference specimen

portion of the reference material that is to be exposed
