PROBLEM TO BE SOLVED: To accurately evaluate the weathering resistance of a polymeric material.SOLUTION: In a first process S101, a first sample made of a material formed of a target polymer is prepared. A blackboard as a standard sample is prepared. Sunlight or light of a xenon arc lamp is radiated to the first sample and blackboard in the same condition. In the state in which the radiation is continued, the surface temperature of the first sample when the surface temperature of the blackboard becomes a set temperature is measured and set as a test temperature. In a second process S102, using the test temperature, an acceleration weathering test of the material is performed with a light source higher than the xenon arc lamp. |
