The Novo-Gloss 45° gloss meter is suitable for measuring gloss of ceramics, metal manufacturing and plastic films.
Gloss has been defined as ‘The attribute of surfaces that causes them to have shiny or lustrous, metallic appearance.’
Manufacturers design their products to have maximum appeal: from highly reflective car body panels to glossy household appliances or matt finish automotive interior trim.
This is especially noticeable where parts may be produced by different manufacturers or factories but will be placed adjacent to one another to create the finished product.
Gloss can also be a measure of the quality of the surface, for instance a drop in the gloss of a coated surface may indicate problems with its cure, leading to other failures such as poor adhesion or lack of protection for the coated surface.
The gloss of a surface can be greatly influenced by a number of factors, for example the smoothness achieved during polishing, the amount and type of coating applied or the quality of the substrate.
It is for these reasons that many manufacturing industries monitor the gloss of their products, from cars, printing and furniture to food, pharmaceuticals and consumer electronics.
It is important therefore that gloss levels are achieved consistently on every product or across different batches of products.
ISO 2813 and ASTM D523 (the most commonly used standards) describe three measurement angles to measure gloss across all surfaces.
Gloss is measured in gloss units (GU) and is traceable to reference standards held at NIST (USA).
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.
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.
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.
This measuring angle is in accordance with the ISO 2457 standard for the gloss measurement of plastic films and solid plastic parts as well as according to the standard ASTM C346 for the gloss measurement of ceramics
