2311200931 ASTM D523是一种用于测量非金属样品的镜面光泽度的标准测试方法,它使用一种称为光泽度计的仪器,根据样品表面反射的光线的方向和强度,给出一个数值表示光泽度的大小。 ASTM D523规定了三种光泽度计的几何角度,分别是60°,20°和85°,这些角度是指光源与样品表面的夹角,不同的角度适用于不同的光泽度范围。
ASTM D523-14(2018) 适用范围 光泽度与表面在接近镜面反射的方向上反射比在其他方向上更多的光的能力相关。通过该测试方法进行的测量与在大致相应角度进行的表面光泽度的目视观察相关。通过将样品的镜面反射率与黑色玻璃标准的镜面反射率进行比较,可以获得通过该测试方法测量的光泽度等级。由于镜面反射率还取决于样品...

ASTM D523 is a standard test method for specular gloss. It is a direct measurement taken with a “gloss meter”. Typically measurements will be taken on a flat, homogeneous and clean surface. The measurement can be taken on a small surface, i.e. 1 cm2but it is preferable to use a ...
