| 中文摘要: |
| 为了更好解读IEC 60068-2-5:2010中的辐照度和温度设定，及如何执行该标准，结合标准中对辐照度和温度设定的要求，提供具体的解决方案。建议在执行标准时，应使用日光过滤片来过滤氙灯光源，实现该标准对光源的要求。同时建议使用340 nm点控制，辐照度设定为0.60 W/m2@340 nm。对于温度的设定，建议按照标准中图2的温度上升、下降与时间的关系，对其进行设定。另外，标准中程序A的循环接近最严酷的自然条件，而程序B和程序C的循环比程序A的严酷很多。因此，一般情况下推荐程序A，对于耐候性好的材料，需要加速测试的，推荐程序B。 |
| 英文摘要: |
| In order to study irradiance and temperature settings specified in IEC 60068-2-5:2010 better, specific solutions were provided based on the setting requirements of irradiance and temperature specified in the standard to solve the problem of how to perform this standard. It was recommended using daylight filter in executing the Standard to meet the light source requirement of the standard. Meanwhile, it was also suggested to use 340nm point control and set the irradiance as 0.60 W/m2@340nm. For the temperature setting, it was recommended referring to the relationship between temperature and time specified in Figure 2 of the standard. In addition, cycle A in the standard was close to the most severe natural conditions, while cycle B and cycle C were more severe than cycle A. Therefore, cycle A was not recommended in general conditions. For the materials with very good weatherability and need accelerated test, cycle B was recommended. |
