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 82541.
