EN ISO 2813:2012 is an international standard that provides a method for determining the specular gloss of non-metallic paint coatings and solid plastics. Gloss is an important visual property that affects the perceived quality and aesthetic appeal of various surfaces. This technical article will delve into the details of this standard, outlining its significance, measurement techniques, and applications.
Measurement Techniques for Specular Gloss
Specular gloss refers to the mirror-like reflection of light from a surface. The EN ISO 2813:2012 standard defines two geometries (angle of incidence and angle of detection) for gloss measurement, which are categorized as "gloss 60°" and "gloss 20°/85°". The former is used for high-gloss applications, while the latter is suitable for both low and medium gloss surfaces.
The equipment used for measuring specular gloss follows specific guidelines outlined in the standard. A gloss meter, equipped with a light source and a receiver, determines the amount of reflected light at the specified angles. Results are expressed as gloss units (GU), with higher values indicating greater glossiness.
Significance and Applications
The EN ISO 2813:2012 standard is crucial in several industries where surface appearance plays a vital role. In automotive manufacturing, gloss measurements ensure consistent quality across various car panels and components. Similarly, in furniture production, this standard guarantees uniformity in the glossy finish of tables, chairs, and other wooden surfaces.
Architectural coatings rely on the EN ISO 2813:2012 standard to achieve desired gloss levels, ensuring architectural structures maintain their intended aesthetics. The printing industry also utilizes gloss measurements for quality control, as glossy paper stock greatly impacts the visual appeal of printed materials.
Conclusion
The EN ISO 2813:2012 standard provides a standardized method for measuring the specular gloss of non-metallic coatings and solid plastics. By employing specific measurement techniques, industries can ensure consistent gloss levels, leading to higher product quality and customer satisfaction. Whether it's automotive, furniture, architecture, or printing, adherence to this standard is essential in achieving desired surface aesthetics.
