标准摘要
[中文适用范围]： 本国际标准规定了用 NIR（近红外）光谱测定多元醇羟值的方法。 给出了定义和校准技术。 概述了选择校准材料以及收集和处理数据以开发 NIR 校准的程序。 还描述了构建、评估和验证 NIR 校准模型的标准。 包括样品处理、数据收集和评估的程序。 为了正确配制聚氨酯体系，有必要了解多元醇的羟值。 本国际标准适用于研究、质量控制、规格测试和过程控制。 [外文原描述]： ISO 15063:2011 specifies a method for the determination of hydroxyl numbers of polyols using NIR (near-infrared) spectroscopy. Definitions and calibration techniques are given. Procedures for selecting calibration materials and for collecting and processing data to develop NIR calibrations are outlined. Criteria for building, evaluating and validating the NIR calibration model are also described. Procedures for sample handling, data gathering and evaluation are included. It is necessary to know the hydroxyl number of polyols in order to properly formulate polyurethane systems. ISO 15063 is suitable for use in research, quality control, specification testing and process control.
