What is BS EN ISO 787-18:2016?

Introduction

BS EN ISO 787-18:2016 is a technical standard that provides guidelines and specifications for the determination of opacity of non-black pigments using an opacimeter. Opacity refers to the ability of a pigment to obstruct the passage of light, resulting in a decrease in transparency. This standard plays a crucial role in various industries, such as paint manufacturing, paper production, and ink formulation, where opacity is an essential characteristic. In this article, we will explore the important aspects and applications of BS EN ISO 787-18:2016.

Understanding Opacity Measurement

Opacity measurement determines the extent to which a pigment hinders the transmission of light through a substrate. It quantifies the scattering and absorption properties of pigments. BS EN ISO 787-18:2016 specifies the operational procedures for measuring opacity using an opacimeter. The opacimeter emits light through a test sample and measures the amount of light transmitted and reflected. By comparing these values with a reference material, the opacity of the pigment under test can be calculated accurately. This standardized method ensures consistency and reliability in opacity measurements across different laboratories and industries.

Importance and Applications

Opacity is a critical property in several industries. For example, in the paint manufacturing industry, opacity determines the quality of paint coverage on surfaces. Paints with high opacity provide better coverage and require fewer coats, resulting in cost savings for consumers. Similarly, in the printing industry, opacity impacts the legibility and vibrancy of printed materials. A higher opacity rating leads to better print contrast and color accuracy. Furthermore, in the paper production industry, opacity affects the readability of text by minimizing show-through from one side of the paper to the other. Compliance with BS EN ISO 787-18:2016 ensures that manufacturers meet the desired opacity standards and produce products of consistent quality.

Conclusion

BS EN ISO 787-18:2016 is an essential technical standard that facilitates the accurate measurement and evaluation of opacity in various industries. By adhering to this standard, manufacturers can ensure product quality, consistency, and compliance with industry requirements. Opacity measurements play a crucial role in determining the effectiveness of pigments in achieving desired properties like coverage, legibility, and vibrancy. Incorporating BS EN ISO 787-18:2016 guidelines into manufacturing processes allows for improved customer satisfaction, increased efficiency, and reduced costs. It is vital for professionals involved in the fields of paint manufacturing, paper production, and ink formulation to adhere to this standard for maintaining quality and facilitating effective decision-making processes.
