What is BS EN ISO 13473-2:2012?

BS EN ISO 13473-2:2012 is a technical standard that provides guidelines and requirements for the determination of particle size distribution in metal powders. It is part of a series of international standards developed by the International Organization for Standardization (ISO) to ensure consistency and reliability in the manufacturing and testing of metallic powders.

Scope and Objectives

The main objective of BS EN ISO 13473-2:2012 is to establish a uniform method for determining the particle size distribution in metal powders. This standard covers the measurement techniques, sample preparation, and data analysis procedures necessary to obtain accurate and repeatable results. It applies to both organic and inorganic metallic powders with a nominal size range of 0.1 µm to 1000 µm.

Measurement Techniques

There are several measurement techniques outlined in BS EN ISO 13473-2:2012 that can be used to determine the particle size distribution in metal powders:

Laser diffraction: This technique measures the scattering pattern produced by particles when illuminated by a laser beam. The pattern is then used to calculate the particle size distribution.

Sedimentation: Sedimentation methods involve allowing particles to settle in a liquid medium under the influence of gravity. The rate of settling is related to the particle size, and this information is used to determine the particle size distribution.

Microscopy: Microscopy techniques, such as optical microscopy and electron microscopy, can provide direct visual observations of particle size and shape.

Conclusion

BS EN ISO 13473-2:2012 is an important standard in the field of metal powders. By providing guidelines and requirements for determining particle size distribution, it ensures consistency and accuracy in the manufacturing and testing of metallic powders. Whether using laser diffraction, sedimentation, or microscopy techniques, adherence to this standard helps to guarantee reliable and comparable results. It is a valuable resource for manufacturers, researchers, and quality control professionals in the metal powder industry.
