测试方法是使用荧光紫外灯和冷凝装置进行曝露测试的基本原则和操作程序,旨在再现材料曝露在阳光下(直接或透过窗玻璃)和曝露在湿气中(雨水或露水)发生的老化效果。 这种做法限制于获取测量和控制的条件和曝光程序的方法,不能指定尽可能适合要测试的材料的曝光条件。

 QUV标准老化箱应用用途

1/全球使用尽可能广泛的耐候测试机,在全球范围内已有数以千计的QUV投入使用。QUV已成为实验室加速耐候试验的世界标准:符合ISO、ASTM G154、DIN、JIS、SAE、BS、ANSI、GM、U.S.GOVT等标准和国标。
2、快速、真实地再现阳光、雨、露对材料的损害:只需要几天或几周时间,QUV可以再现户外需要数月或数年才能产生的破坏:包括褪色、变色、亮度下降、粉化、龟裂、变模糊、脆化、强度下降及氧化。

ASTM G154标准老化箱辐照度控制


         为了达到精确且可重复的测试结果,有必要控制辐照度(光强)很有必要。大多数型号QUV都装备有日光眼光强控制器。这种精确的光控系统为使用者提供了选择辐照度度的方便。利用日光眼的反馈循环系统,可以连续地、自动地控制且精确地保持辐照度。日光眼靠调整灯的功率来自动地补偿灯管老化和其他因素造成的光强变化。图4展示了辐照度控制系统工作原理。在仅仅几天或几周内,QUV老化箱能模拟在室外经几个月甚至几年所造成的损害。

所形成的冷凝物是非常稳定,纯度很高的蒸馏水。这种高纯的蒸馏水增加了测试结果的可重复性,也简化了QUV的安装和操作。
因为材料在室外经受潮湿侵蚀的时间很长,所以QUV要达到相同的效果,它的冷凝循环过程至少需要4 h。另外,冷凝过程是在一较高温度(一般为50 ℃)下进行的,这大大加速了潮湿侵蚀。

ASTM G154标准介绍

XIANGXIJIESHAOQINGFANGWEN:

附:ASTM G154 英文版本(摘抄)

Designation: ASTM G154直播吧手机版 – 05 a Standard Practice forOperating Xenon Arc Light Apparatus for Exposure of Non-Metallic Materials1

This standard is issued under the fixed designation ASTM G154; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 This practice covers the basic principles and operating procedures for using xenon arc light and water apparatus intended to reproduce the weathering effects that occur when materials are exposed to sunlight (either direct or through window glass) and moisture as rain or dew in actual use. This practice is limited to the procedures for obtaining, measuring and controlling conditions of exposure. A number of exposure procedures are listed in an appendix; however, this practice does not specify the exposure conditions best suited for the material to be tested.

NOTE 1—Practice ASTM G151 describes performance criteria for all exposure devices that use laboratory light sources. This practice replaces Practice G 26, which describes very specific designs for devices used for xenon-arc exposures. The apparatus described in Practice G 26 iscovered by this practice.

直播吧手机版1.2 Test specimens are exposed to filtered xenon arc light under controlled environmental conditions. Different types of xenon arc light sources and different filter combinations are described.

1.3 Specimen preparation and evaluation of the results are covered in ASTM methods or specifications for specific materials. General guidance is given in Practice ASTM G151 and ISO 4892-1. More specific information about methods for determining the change in properties after exposure and reporting these results is described in Practice D 5870.

直播吧手机版1.4 The values stated in SI units are to be regarded as the standard.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

直播吧手机版1.5.1 Should any ozone be generated from the operation of the lamp(s), it shall be carried away from the test specimens and operating personnel by an exhaust system.

直播吧手机版1.6 This practice is technically similar to the following ISO documents: ISO 4892-2, ISO 11341, ISO 105 B02, ISO 105 B04, ISO 105 B05, and ISO 105 B06.
