标准范围

规定的方法提供了ISO 787/16和ISO 787/17中所述方法的仪器替代方法。相同质量的有色材料分别分散在相同质量的白色颜料膏中。通过光度法测量每个色散的反射率。根据相应的K/S值，给出了相对着色强度。为了测量相对散射功率，将同等质量的白色试验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膏中。在550 nm处用光度法测量每个色散的反射率。根据相应的K/S值，给出了相对散射功率。

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.
