Comparative study of methods for measurin window film UV and Luminous transmittance


Jos P. Caly; Antonio Francisco Gentil Ferreira Jr.


Resumo:

This work presents a comparison of window film ultraviolet transmission calculated according ISO 13837 methods A and B and window film luminous transmission calculated for illuminates A and D65. The results show a difference from 350% to 800% in ultraviolet transmission between ISO 13837 methods A and B for the evaluated window films. On the other hand, the difference in luminous transmission results for the evaluated window films is less than 1%.
