ISO 4892-2:2013指定了樣品暴露在氙燈光照環(huán)境下，模擬戶外綜合老化效果（包括溫度、濕度/潮濕環(huán)境下）的測(cè)試方法，以再現(xiàn)產(chǎn)品在實(shí)際使用過程中暴露在光照環(huán)境或者經(jīng)過窗玻璃過濾的光照環(huán)境產(chǎn)生的老化效果。
英文摘要
ISO 4892-2:2013 specifies methods for exposing specimens to xenon-arc light in the presence of moisture to reproduce the weathering effects (temperature, humidity and/or wetting) that occur when materials are exposed in actual end-use environments to daylight or to daylight filtered through window glass.
ISO 4892-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 6, Ageing, chemical and environmental resistance.
This third edition cancels and replaces the second edition (ISO 4892-2:2006), which has been technically revised. It also cancels and replaces the Amendment ISO 4892-2:2006/Amd.1:2009.
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
1 Scope
This part of ISO 4892 specifies methods for exposing specimens to xenon-arc light in the presence of moisture to reproduce the weathering effects (temperature, humidity and/or wetting) that occur when materials are exposed in actual end-use environments to daylight or to daylight filtered through window glass.
Specimen preparation and evaluation of the results are covered in other International Standards for specific materials.
General guidance is given in ISO 4892-1.
NOTE Xenon-arc exposures of paints and varnishes are described in ISO 11341.
