17、In addition, there shall be no cracking, crazing or other deterioration. The material must remain flexible and exhibit no cracking when bent around a 20 +/- 2 mm mandrel after the specified exposure. Note: In case of differences in the test results between Florida exposure and the accelerated weathe
18、ring the results of the Florida exposure shall prevail. One year Florida weathering is required for all seamless instrument panel applications before the technology can be implemented. Once Florida weathering performance is established then Filtered Xenon results may be used for new colors of existing technologies. 4.
