ASTM D1003-21 适用范围 当透过材料观察物体时,穿过材料薄膜或片材时散射的光会产生模糊或烟熏的视野。另一种影响可能是遮蔽眩光,就像在阳光下行驶时汽车挡风玻璃上出现的情况一样。虽然雾度测量最常见的是使用雾度计,但也可以使用分光光度计,只要它满足第 5 节的几何和光谱要求。使用分光光度计测量塑料的雾度可...
ASTM D1003是由美国材料与试验协会(ASTM)制定的标准,可用于测量塑料、玻璃及其他透明或半透明材料的光学透明度。它是评估材料透明度的一种重要方法,可在品质控制和质量保证等领域得到广泛应用。 ASTM D1003标准测试方法主要通过测量样品与可见光的相互作用来评估材料的透明度。在测试过程中,样品通常被切割成均匀而透明的...
ASTM D1003标准是用于测试透明或透光材料的透光度的标准。这个标准适用于任何透明或透光材料,包括塑料、玻璃、涂料、薄膜等。透光度是一个描述材料光透过能力的物理特性,它是通过测量光线通过材料时的亮度来确定的。这个标准通过使用特定的光波长、光源和光探测器来测量透光度,以确保结果的准确性和可重复性。 ASTM D...
