What is ISO 4892-1 - Plastics exposure to laboratory light source about?
Plastics are widely popular because they are durable, flexible, lightweight and can be shaped into any form.
ISO 4892-1 provides information and general guidance relevant to the selection and operation of the methods of exposure described in detail in subsequent parts. ISO 4892-1 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 ISO 4892-1 the term “light source” refers to radiation sources that emit UV radiation, visible radiation, infrared radiation or any combination of these types of radiation.
Who is ISO 4892-1 - Plastics exposure to laboratory light source for?
ISO 4892-1 on plastics exposure to laboratory light source is useful for organizations associated with:
- Manufacturing of plastics
- Testing of plastics
- Research and development teams
- Quality control teams
Why should you use ISO 4892-1 - Plastics exposure to laboratory light sources?
Plastics are often used outdoors and indoor locations where they are exposed to solar radiation or solar radiation behind the glass for long periods. It is therefore very important to determine the effects of solar radiation, heat, moisture and other climatic stresses on the colour and other properties of plastics. Outdoor exposures to solar radiation and solar radiation filtered by window glass are described in ISO 877.
ISO 4892-1 provides information on the interpretation of data from artificial accelerated weathering or artificially 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.
ISO 4892-1 provides you with detailed test-related information including:
- Use of accelerated tests with laboratory light sources
- Irradiance
- Temperature
- Humidity and wetting
- Setpoints for exposure conditions
- Property measurements on test specimens
- Set points for exposure conditions
- Property measurements on test specimens
The guidelines in ISO 4892-1 help you run the test to observe plastic’s reactivity towards exposures to artificial weathering and determine their longevity, so that end customers can use superior quality products.
