METHOD FOR DISTINGUISHING MINERAL WOOLS AND SYSTEM FOR DISTINGUISHING MINERAL WOOLS

摘要

Process for distinguishing glass wool and rock wool with the following steps: provision of near infrared spectra (NIR spectra) of glass wool and rock wool as calibration spectra; Providing a sample comprising a glass wool or a rock wool; Creating an NIR spectrum of the sample; Defining a decision criterion for assigning the sample as glass wool or as rock wool; Computer-aided determination of the decision criterion by a multivariate method with the entries in the NIR spectrum of the sample and the NIR spectra as calibration spectra.
