| Abstract: |
| The solar radiation was the most important factor of organic material weathering. Because the level of the solar radiation in Lhasa of tableland was twice higher than in backland of the same latitude, the weathering rate of organic coating was consumedly elevated for the samples tested in Lhasa. The accelerated outdoor weathering test and natural exposure test of four types of common protective coating was carried out in Lhasa. The relative durability of the materials was determined and the acceleration rate of the method was validated. |
