Standard Test Method for Specular Gloss of Glazed Ceramic Whitewares and Related Products


1.1 This test method covers the determination of 60 specular gloss of glazed ceramic whitewares and related products.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Significance and Use

This test method provides a means of establishing specular gloss limits for bright, semi-mat, and mat glazed surfaces. It is realized that specular gloss measurements do not always correlate well with visual rankings of glossiness because specular gloss is only one of several related appearance attributes that produce the sensation of gloss. However, the prescribed test method is of sufficient accuracy for the intended purpose.

Note 1—If a greater degree of distinction between bright glazed surfaces is desired, the 20° geometry instrument will provide it.4
