An ARPANSA Protection Factor Report for films, glass and other materials contain the following results: • The company the report was prepared for • The sample and colour as described by the supplier • The analysis date and on what instrument the test was performed on • A generic description, such as Clear Polyethylene Film, 0.15mm • Mean UVA Transmission: The average UVA (315 to 400 nm) radiation passing through the film. • Mean UVB Transmission: The average UVB (290 to 315 nm) radiation passing through the film. • Protection Factor (PF): The protection factor (PF) is calculated by comparing the photo-biologically effective irradiance without and with the test material in place for each sample and then averaged for the number of specimens analysed. • Standard Deviation: This indicates how much variation in PF rating there is across the surface of the material. • Calculated PF: The mean PF minus the standard deviation. • Number of Specimens Analysed: This shows how many measurements were made on the material. • Ultraviolet Radiation Blocked: The percentage photo-biologically effective UVR blocked by the material. • Material Sample: For positive identification, a sample of the material tested, or an image of the product, is attached to the report. • Transmission Characteristics: The graph shows the average of the measured transmissions.
