Plastics& Test methods of exposure to natural weathering

GB/T3681-1983塑料自然气候曝露试验方法

Both weathering steel and carbon steel were tested using an accelerated atmospheric corrosion test of dry wet cyclic immersion by 3.5% NaCl solution.

以3.5%的NaCl溶液为腐蚀剂，对碳钢和耐候钢进行干湿循环加速腐蚀实验。

Test method for exposure to natural weathering on pipeline protective coating

管道防腐层自然气候曝露试验方法

Characteristics of Soil Erosion on the Side Slope of Constructing Expressway from Tongxin to Guyuan; accelerated weathering test

在建高速公路边坡土壤侵蚀特性研究加速风蚀试验，加速老化试验

Through the atmospheric exposure comparison test of different coating systems, the difference of weathering resistance in different coating systems is discussed. The difference of two-coat and three-coat is summarized, and possibility of simplifying coating system is advanced as well.

通过不同涂装体系的耐候性对比试验，探讨了不同涂装体系在自然曝晒条件下耐候性的差异，从而总结出两涂层和三涂层的差异，并提出了简化涂装体系的可能性。

Artificial Weathering Test of Automobile Inner Materials

汽车内饰材料的人工老化试验

Natural and artificial weathering test are general methods that determine weathering properties of polymer.

自然大气暴露和人工加速老化都是评价高聚物老化特性的常用方法。
