Publication Date: 1 June 2009
Status: inactive
Page Count: 3
ICS Code (Paints and varnishes): 87.040
significance And Use:

Measured gloss values of specimens depend on the angle of illumination, refractive index of the material, and the geometric distribution of the reflected light.

scope:

1.1 This test method describes a procedure for using two specular gloss measurements to obtain a haze index for high-gloss nonmetallic specimens (1-4). It is particularly useful for evaluating the haze in clear finishes on nonglossy substrates, and the haze in reflected images produced by the surfaces of opaque glossy pigmented finishes.

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.
