33、ization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been establish

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

39、document is ISO/TC 61, Plastics, Subcommittee SC 6, Ageing, chemical and environmental resistance.This third edition cancels and replaces the second edition (ISO 4892-1:1999), which has been technically revised.ISO 4892 consists of the following parts, under the general title Plastics Methods of exp
40、osure to laboratory light sources: Part 1: General guidance Part 2: Xenon-arc lamps Part 3: Fluorescent UV lamps Part 4: Open-flame carbon-arc lamps4DIN EN ISO 4892-1:2016-10 EN ISO 4892-1:2016 (E)IntroductionPlastics are often used outdoors or in indoor locations where they are exposed to solar rad
41、iation or to solar radiation behind 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 to solar radiation filtered by w
42、indow glass are described in ISO 877 (all parts).1However, it is often necessary to determine more rapidly the effects of radiation, heat and moisture on the physical, chemical and optical properties of plastics with artificial accelerated weathering or artificial accelerated irradiation exposures t
43、hat use specific laboratory light sources. Exposures in these laboratory devices are conducted under more controlled conditions than found in natural environments and are intended to accelerate eventual polymer degradation and product failures.Relating results from accelerated weathering or artifici
44、al accelerated irradiation exposures to those obtained in actual-use conditions is difficult because of variability in both types of exposure and because laboratory tests never reproduce exactly all the exposure stresses experienced by plastics exposed in actual-use conditions. No single laboratory
45、exposure test can be specified as a total simulation of actual-use exposures.The relative durability of materials in actual-use exposures can be very different depending on the location of the exposure because of differences in UV radiation, time of wetness, temperature, pollutants and other factors
46、. Therefore, even if results from specific accelerated weathering or artificial accelerated irradiation exposures are found to be useful for comparing the relative durability of materials exposed in a particular outdoor location or in particular actual-use conditions, it cannot be assumed that they
47、will be useful for determining the relative durability of materials exposed in a different outdoor location or in different actual-use conditions.5DIN EN ISO 4892-1:2016-10 EN ISO 4892-1:2016 (E)1 ScopeThis part of ISO 4892 provides information and general guidance relevant to the selection and oper
48、ation 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 art
49、ificial 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.This part of ISO 4892 also provides information on the interpretation of data from artificial accelerated weathering or artificial accelerated irradiation exposures.
