标准摘要
[中文适用范围]： 指定的方法为 ISO 787/16 和 ISO 787/17 中描述的方法提供了仪器替代方法。 等质量的有色材料分别分散在相同质量的相同白色颜料浆中。 每种分散体的反射率均通过光度测定法测量。 从相应的 K/S 值可以得出相对着色强度。 为了测量相对散射能力，将等质量的白色测试材料和商定的参考颜料分别分散在相同质量的相同黑色颜料糊中。 每种分散体的反射率均在 550 nm 处进行光度测定。 从相应的 K/S 值可以得出相对散射功率。 [外文原描述]： The method specified provide an instrumental alternative to those described in ISO 787/16 and ISO 787/17. Equal masses of a coloured material are separately dispersed in the same mass of the same white pigment paste. The reflectivity of each dispersion is measured photometrically. From the corresponding values of K/S the relative tinting strength is given. For measurement of the relative scattering power equal masses of a white test material and an agreed reference pigment are separately dispersed in the same mass of the same black pigment paste. The reflectivity of each dispersion is measured photometrically at 550 nm. From the corresponding values of K/S the relative scattering power is given.
