3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Calibration model calibrationmodel A mathematical model of the relationship between the near-infrared spectrum of a sample and the corresponding chemical standard value established by chemometric methods. Note calibration model Includes qualitative and quantitative models. Qualitative model is based on a large amount of information and data, based on expert experience and existing knowledge. The process of automatic recognition and evaluation of shapes, patterns, curves, numbers and graphs by means of computer and mathematical reasoning; quantitative model It is a mathematical relationship established between the concentration of a substance (or other physicochemical property) and the response of an analytical instrument. Example. A near-infrared qualitative model of a mixture of polyester fibers and wool determines whether the sample contains a polyester fiber and wool identification model. Polyester Near-infrared Quantitative Model of a Mixture with Wool, Using Near-Infrared Spectroscopy and Standard Method for Establishing a Mixture of Wool and Polyester Fiber Using Chemometrics (GB/T 2910.1, GB/T 2910.4) The mathematical relationship between the fiber contents of the samples obtained. 3.2 Monitor sample monitorsamples Uniform sample of the same variety used to monitor the daily working stability of the near-infrared analyzer. Note. This sample is an essential accessory for NIR instruments equipped with a polyester/wool near-infrared analysis model. 3.3 Very poor range In the multiple predictions of the same sample, the difference between the maximum value and the minimum value of the predicted value is calculated as Xmax-Xmin. 3.4 Fiber content nominal value identificationoffibercontent The nominal value of the percentage of textile fiber content to be tested, such as "15% polyester fiber/85% wool" "75% polyester fiber/25% wool".
