ISO 13320 Particle Size Distribution by Laser Diffraction
The ISO 13320 standard is a cornerstone in the field of powder metallurgy and additive manufacturing, providing a robust method for determining particle size distribution through laser diffraction. This technique is widely used to assess particles ranging from nanometers to millimeters, offering unparalleled precision and versatility.
This service is crucial for quality managers, compliance officers, R&D engineers, and procurement teams who need reliable data on the physical characteristics of powders. Particle size distribution significantly influences processability, mechanical properties, and performance in various applications across industries such as automotive, aerospace, electronics, and medical devices.
The laser diffraction method measures the scattering pattern of light from a collimated beam when it encounters particles suspended in a carrier liquid. This interaction generates information about particle sizes based on the angle at which the scattered light is detected. The precision and accuracy of this method make it indispensable for ensuring product quality, process optimization, and regulatory compliance.
The testing procedure involves several critical steps: preparation of the sample, calibration of equipment, measurement setup, data acquisition, and analysis. Proper specimen preparation ensures accurate results, which can be achieved by dispersing particles in a suitable liquid carrier to achieve a stable suspension. Calibration is essential for ensuring that the instrument responds accurately to known particle sizes.
The key instruments used include laser diffraction analyzers equipped with advanced optical systems designed to capture detailed scattering patterns from the dispersed particles. Data acquisition and analysis are typically performed using software provided by the manufacturer, which processes raw data into meaningful distributions of particle size.
Accurate reporting is vital for compliance and quality assurance purposes. Reports generated from this service detail the measured particle sizes along with statistical parameters such as mean diameter, volume median, and weight median diameters. These metrics provide a comprehensive overview of the powder's characteristics, aiding in process optimization and product development.
