摘要

BS ISO 2470-1:2016 specifies a method for measuring the diffuse blue reflectance factor (ISObrightness) of pulps, papers and boards.This part of ISO 2470 is limited in its scope to white and near-white pulps, papers and boards. Themeasurement can only be made in an instrument in which the ultraviolet energy level of the illuminationhas been adjusted to correspond to the CIE illuminant C[6] using a fluorescent reference standard.The CIE illuminant C is taken to be representative of indoor daylight conditions because it contains asuitable proportion of UV radiation.[9]NOTE The property called D65 brightness is measured with an instrument adjusted to correspond with CIEstandard illuminant D65,[4] which has a much higher UV content than that specified in this part of ISO 2470. The measurement of D65 brightness is described in ISO 2470-2.[2]Cross References:ISO 186ISO 2469ISO 3688ISO 4094ISO 7213ISO 187ISO 2470-2ISO/TR 10688ISO 11664-2:2007ISO/TR 24498CIE 15:2004CIE S017:2011CIE 182:2007All current amendments available at time of purchase are included with the purchase of this document. BS ISO 2470-1:2016规定了蓝色漫反射系数（ISO纸浆、纸张和纸板的亮度。ISO 2470的这一部分仅限于白色和接近白色的纸浆、纸张和纸板。这个只能在照明的紫外线能级已使用荧光参考标准对其进行调整，以与CIE光源C[6]相对应。CIE光源C被视为室内日光条件的代表，因为它包含适当比例的紫外线辐射。[9] 注:被称为D65亮度的特性是通过调整仪器以符合CIE进行测量的标准光源D65，[4]，其紫外线含量远高于ISO 2470本部分规定的紫外线含量。ISO 2470-2中描述了D65亮度的测量。[2] 交叉引用:ISO 186ISO 2469ISO 3688ISO 4094ISO 7213ISO 187ISO 2470-2ISO/TR 10688ISO 11664-2:2007ISO/TR 24498CIE 15:2004CIE S017:2011CIE 182:2007购买本文件时提供的所有当前修订均包含在购买本文件中。展开▼
