Resumo
Individual dosimetry and the shielding of sun rays are needed for people in homes, at workplaces and vehicles when exposed to Ultraviolet Radiation (UVR) and/or Infrared Radiation (IR). Usually, the efficacy of Solar Protective Films (SPF) has been recognized as an important public health concern. So, this work aimed to verify, using the Design of Experiments (DoE) and Multiple Linear Regression (MLR) methods, the evaluation of solar films using the UV–Vis and NIR (Near Infrared) spectrophotometry technique for absorbance readings. In addition, the significance of the SPF manufacturing origin and glass color were evaluated. Four types of SPF, named G05, G20, G35 and WB, were tested and layered within dark and light glasses. The absorbance readings were used in a 2k factorial design analysis, then the one-way ANOVA Test and the Bonferroni Test were used to assess the statistical significance of each factor. The results showed that the statistical error, using the Root Mean Square Percentage Error (RMSPE) and the Mean Absolute Percentage Error (MAPE) methods, showed values less than 0.014% between the measured and the predicted ones, indicating excellent accuracy. In conclusion, DoE and MLR methods are suitable to be used in the investigation of the association between SPF and glass materials.
