1.1This standard covers a practice for the determination of hydroxyl numbers of polyols using NIR spectroscopy.
1.2Definitions, terms, and calibration techniques are described. Procedures for selecting samples, and collecting and treating data for developing NIR calibrations are outlined. Criteria for building, evaluating, and validating the NIR calibration model are also described. Finally, the procedure for sample handling, data gathering and evaluation are described.
1.3The implementation of this standard requires that the NIR spectrometer has been installed in compliance with the manufacturer's specifications.
1.4The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
