ISO 8254-3:2016规定了一种测量纸张和纸板镜面光泽度的方法，该方法与纸张表面的法线成20°角。它主要适用于高光泽表面，如铸涂、喷漆、高清漆或蜡纸和高光泽油墨膜。 注:ISO 8254的这一部分是根据TAPPI T653[2]、ISO 2813[1]和ISO 8254-1开发的。

ISO 8254-3:2016 specifies a method for measuring the specular gloss of paper and board at an angle of 20° to the normal to the paper surface. It is applicable chiefly to highly glossy surfaces, such as cast-coated, lacquered, highly varnished or waxed papers and high-gloss ink films. NOTE This part of ISO 8254 has been developed from TAPPI T653[2], ISO 2813[1] and from ISO 8254？1.
