标准范围

ISO 2469:2014描述了测量所有类型纸浆、纸张和纸板漫辐射系数的一般程序。更具体地说，它详细规定了用于此类测量的设备的特性，以及用于校准该设备的程序。ISO 2469:2014可用于测量含有荧光增白剂的材料的漫射辐射系数和相关特性，前提是已调整仪器照明的UV含量，以提供与选定CIE光源的荧光参考标准相同的荧光水平，按照特定的国际标准描述相关财产的计量。ISO 2469:2014描述了荧光参考标准的制备，但不包括使用这些标准的程序，因为它们的使用在描述含荧光增白剂材料性能测量的特定国际标准中有详细描述。

ISO 2469:2014 describes the general procedure for measuring the diffuse radiance factor of all types of pulp, paper and board. More particularly, it specifies in detail the characteristics of the equipment to be used for such measurements, and the procedures to be used for calibrating that equipment.ISO 2469:2014 may be used to measure the diffuse radiance factors and related properties of materials containing fluorescent whitening agents, provided that the UV-content of the instrument illumination has been adjusted to give the same level of fluorescence as a fluorescent reference standard for a selected CIE illuminant, in accordance with the specific International Standard describing the measurement of the property in question.ISO 2469:2014 describes the preparation of fluorescent reference standards, although the procedures for using these standards are not included, since their use is described in detail in the specific International Standards describing the measurement of the properties of materials containing fluorescent whitening agents.
