Measuring method for determining a protection factor, and protection factor evaluation system

Abstract

The invention describes a method for determining a protection factor, comprising a spectroscopic measurement with the method steps of emitting radiation from a beam source, with the emitted radiation comprising light at an irradiation wavelength of between 280 nm and 2000 nm, irradiating a measuring body using the emitted radiation, detecting the radiation diffusely reflected by the irradiated measuring body at a detection wavelength, evaluating the protection factor of a protection means at an evaluation wavelength from the diffusely reflected radiation and a transmission spectrum, with the data of a transmission spectrum being used for the evaluation of the protection factor of the protection means, with the evaluation wavelength differing from the wavelength range of the irradiation wavelength and/or the detection wavelength, and with the data of the transmission spectrum being in silico data. The invention also describes an SPF evaluation system for examining the protection factor of protection means, comprising the following components: a measuring device having a beam source device, the beam source device comprising a beam source, a detector unit, a control unit for controlling the measuring device, and an evaluation unit.
