What is EN ISO 27348:2011?

The Purpose of EN ISO 27348:2011

EN ISO 27348:2011 is a technical standard that addresses specific requirements for the determination of the particle size distribution of powders by means of sedimentation methods. Its purpose is to establish a uniform methodology and provide accurate results for various industrial applications.

The Importance of Particle Size Distribution Analysis

Particle size distribution analysis plays a critical role in many industries, such as pharmaceuticals, cosmetics, food processing, and materials science. It provides valuable information about the physical properties of powders, including their flowability, stability, and performance. By understanding the particle size distribution, manufacturers can optimize processes, improve product quality, and ensure consistent results.

The Principles of EN ISO 27348:2011

EN ISO 27348:2011 employs the principle of sedimentation methods to determine the particle size distribution. This involves allowing particles to settle in a liquid medium under the influence of gravity. The time it takes for particles to settle is directly related to their size and density. By measuring the settling rates of particles at different time intervals, the particle size distribution can be calculated using mathematical models.

The Benefits of EN ISO 27348:2011

EN ISO 27348:2011 offers several advantages to users. Firstly, it provides a standardized approach to particle size distribution analysis, ensuring consistency and comparability of results across different laboratories. Secondly, it specifies the necessary equipment, procedures, and calculations required for accurate measurements. Lastly, it includes guidelines on reporting and presenting the obtained data, allowing for easy interpretation and effective communication between stakeholders.
