EN ISO 472:2014 is a technical standard that provides guidelines and specifications for the designation of colors and colorants used in various industries. Adopted by the European Committee for Standardization (CEN), this standard is based on international standards such as ISO 472:1988.
Scope and Purpose
The purpose of EN ISO 472:2014 is to establish a uniform system for the designation of colors, including pigments, dyes, and other colorants. It aims to promote consistency in color communication and ensure compatibility between different materials and products in the manufacturing process.
This standard covers a wide range of applications, including but not limited to:
Plastics
Pigments and dyes
Inks and paints
Fibers and textiles
Ceramics
Main Requirements
EN ISO 472:2014 lays down specific requirements for the designation and coding of colors and colorants. Some of the main requirements include:
Color space: The standard defines the color space used for color measurement and communication, such as CIE L*a*b* or CIE XYZ.
Color notation: It specifies the notation system for color designations, which may be numerical, alphabetic, or a combination of both.
Color difference calculation: The standard outlines the formulas and methods for calculating the differences between colors, allowing for accurate color matching and reproduction.
Tolerances: EN ISO 472:2014 provides tolerance values for color differences, ensuring permissible deviations from the specified color.
Benefits and Applications
Adhering to EN ISO 472:2014 brings several benefits to various industries:
Improved color accuracy and consistency in manufacturing processes
Easier color communication between suppliers and customers
Reduced rejections and waste due to color mismatch
Enhanced product quality and aesthetics
Compliance with international standards for color designation
In summary, EN ISO 472:2014 plays a crucial role in standardizing color designations across different materials and industries. By following its guidelines, manufacturers can ensure accurate color reproduction and maintain consistent quality throughout the supply chain.
