Gloss is measured in gloss units (GU) this is traceable to reference standards held at NPL (UK) NIST (Germany) or NRC (Canada). High Gloss: 20?  The acute measurement angle of 20? gives improved resolution for high gloss surfaces. Surfaces that measure 70GU and above at the standard angle of 60? are often measured with this geometry. The 20? angle is more sensitive to haze effects that affect the appearance of a surface. Universal Measurement Angle: 60? All gloss levels can be measured using the standard measurement angle of 60?. This is used as the reference angle with the complimentary angles of 85? and 20? often used for low and high gloss levels respectively. Low Gloss: 85? For improved resolution of low gloss a grazing angle of 85? is used to measure the surface. This angle is recommended for surfaces which measure less than 10GU when measured at 60?. This angle also has a larger measurement spot which will average out differences in the gloss of textured or slightly uneven surfaces.

For polished metal surfaces haze is often associated with polishing marks or chemical residue.

Reflection haze is an optical phenomenon associated with high gloss surfaces. A common surface issue that can reduce the quality of the appearance. A hazy surface has a visibly shallower reflection and halos appear around reflections of strong light source as the there reflection is shallower.

No Haze, deep reflection

High Haze, ?shallow? finish

A high gloss finish with haze exhibits a milky finish with low reflective contrast- reflected highlights and lowlights are less pronounced.

Low Haze

Higher Haze

Halos are visible around the reflections of strong light sources on surfaces with haze.
