ISO4892 国际标准以“塑料—暴露于实验室光源的方法”为总标题，由以下部分组成：

第1部分：通则；

第2部分：氙弧灯；

第3部分：荧光紫外灯；

第4部分：开放式碳弧灯，紫外光老化试验箱ISO 4892 的本部分的附录A仅作参考之用。

ISO 4892-2:2013指定了样品暴露在氙灯光照环境下，模拟户外综合老化效果（包括温度、湿度/潮湿环境下）的测试方法，以再现产品在实际使用过程中暴露在光照环境或者经过窗玻璃过滤的光照环境产生的老化效果。

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 evalsuation 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.
