    ISO 4892

     

    Welcome To Pacific Certifications!

    ISO 4892 Plastics — Methods of exposure to laboratory light sources

    ISO 4892 consists of the following parts, under the general title Plastics — Methods of exposure to laboratory light sources:
    — Part 1: General guidance
    — Part 2: Xenon-arc lamps
    — Part 3: Fluorescent UV lamps
    — Part 4: Open-flame carbon-arc lamps
    ISO 4892-1:2016(EN) Plastics — Methods of exposure to laboratory light sources — Part 1: General guidance
    ISO 4892-1:2016 shares general guidelines that are 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.
    ISO 4892-1:2016 also shares 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 are given in ISO 4582.

    ISO 4892-2:2013(EN) Plastics — Methods of exposure to laboratory light sources — Part 2: Xenon-arc lamps
    ISO 4892-2:2013 was created by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 6, Ageing, chemical, and environmental resistance.
    ISO 4892-2:2013 provides methods for exposing specimens to xenon-arc light in the presence of moisture to reproduce the weathering effects that occur when materials are exposed in the actual end-use environment to daylight or to daylight filtered through window glass
    ISO 4892-3:2016 (EN) Plastics — Methods of exposure to laboratory light sources — Part 3: Fluorescent UV lamps
    ISO 4892-3:2016 shares methods for exposing specimens to fluorescent UV radiation, heat and water in apparatus designed to simulate the weathering effects that occur when materials are exposed in actual end-use environments to global solar radiation, or to solar radiation through window glass.
    The specimens are exposed to fluorescent UV lamps under controlled environmental conditions like temperature, humidity and/or water. Different types of fluorescent UV lamp can be used to meet all the requirements for testing different materials.
    ISO 4892-4:2013(EN) Plastics — Methods of exposure to laboratory light sources — Part 4: Open-flame carbon-arc lamps
    ISO 4892-4:2013 defines methods for exposing specimens to open-flame carbon-arc lamps in the presence of moisture to reproduce the weathering effects that occur when materials are exposed in actual end-use environments in daylight or daylight filtered through a window glass.
    The specimens are exposed to filtered open-flame carbon-arc light under controlled environmental conditions (temperature, moisture). Various filters are mentioned
