significance And Use:

An important aspect of the appearance of glossy coating surfaces is the distinctness (clarity) of images reflected by them. The values obtained by the measuring procedures given in these methods... View More

scope:

1.1 This test method describes the measurement of the distinctness-of-image (DOI) gloss of coating surfaces using electro-optical measuring techniques. The coatings must be applied to planar rigid surfaces. The scale values obtained from the alternative methods cited do not agree.

1.2 Three test methods are covered as follows:

1.2.1 Test Method AGloss reflectance factor measurements are made on the specimen at the specular viewing angle and at an angle slightly off the specular viewing angle. The values obtained are combined to provide a DOI value. Very narrow source and receptor aperture angles are used in the measurements.

1.2.2 Test Method BThe light through a small slit is projected on the specimen surface and its reflected image intensity is measured through a sliding combed shutter to provide a value of image clarity.

1.2.3 Test Method CThe light through a pattern is projected on the specimen surface and its reflected image intensity is measured directly to provide a value of image clarity.

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