The work of preparing International S
10、tandards is normally carried out through ISOtechnical committees. Each member body interested in a subject for which a technical committee has beenestablished has the right to be represented on that committee. International organizations, governmental andnon-governmental, in liaison with ISO, also t
11、ake part in the work. ISO collaborates closely with the InternationalElectrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is
12、to prepare International Standards. Draft International Standardsadopted by the technical committees are circulated to the member bodies for voting. Publication as anInternational Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility th
13、at some of the elements of this document may be the subject of patentrights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 4582 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 6, Ageing, chemicaland environmental resistance.This third ed
14、ition cancels and replaces the second edition (ISO 4582:1998), which has been technically revised.ISO 4582:2007(E) ISO 2007 All rights reserved vIntroductionA number of different exposure techniques can be used to provide information on the effects of environmentalstresses such as light, heat and wa
15、ter on plastics (see ISO 877 and ISO 4892). Each exposure test has its ownparticular application and relevance. When determining changes in a particular property or attribute of amaterial subjected to different exposures, the same evaluation methods should be used after all exposures toensure meanin
16、gful results.Results for plastics subjected to exposure tests are strongly dependent on the type of exposure conditionsused, the type of plastic being tested and the property being evaluated. A result obtained for one property maynot be the same as that for a different property of the same material,
17、 even if the same exposure test is used.This standard is not intended to establish a fixed procedure for conducting the exposure test, but is intended toprovide a set of specific procedures used to express the results for change in a characteristic property of thematerial after it has been exposed.
18、It is up to the user to determine which exposure conditions are most relevantto the specific material and the service conditions being used.Test methods should be selected to determine changes in appearance and properties of the exposed materialwith its proposed application in mind. The exposure tes
19、t used should be devised to discriminate amongmaterials based on such changes. This standard suggests typical properties that can be used to determinechanges in plastics which have been subjected to exposure tests.NOTE Because of large differences in the spectral distribution of the light sources us
20、ed, there can be large differences inresults for the same plastics exposed in the various devices described in ISO 4892. Therefore, comparisons betweenplastics should only be made based on results from exposures in the same type of device and under the same conditions.For optimum comparisons, plasti
21、cs should be exposed at the same time in the same device.vi INTERNATIONAL STANDARD ISO 4582:2007(E) ISO 2007 All rights reserved 1Plastics Determination of changes in colour and variations in properties after exposure to daylight under glass, natural weathering or laboratory light sources1ScopeThis
22、International Standard describes procedures used to determine changes in colour and other appearanceproperties, and variations in mechanical or other properties, of plastics that have been exposed to daylightbehind glass, to natural weathering or to light from a laboratory source. The procedure used
23、 to analyse datadepends on whether the test used to characterize the materials being exposed is destructive or non-destructive.The exposures are conducted under conditions described in specific exposure standards.2 Normative referencesThe following referenced documents are indispensable for the appl
