Actors in the field of metallurgy, you would like to characterise metallic powders according to the ISO 52907 standard
Testing of metallic powders according to ISO 52907 standard
Metallic powders are at the heart of many innovative industrial processes: additive manufacturing, powder metallurgy, surface coatings, etc.
Their quality directly influences the performance of the parts produced: consistency, mechanical properties, reliability, and safety.
The ISO 52907 standard defines the requirements and test methods for the characterization of metal powders intended for additive manufacturing. It provides an essential framework for ensuring traceability, regulatory compliance, and quality control of your raw materials.

Why characterize metallic powder according to ISO 52907?
The quality of a metallic powder directly influences the manufacturing and performance of parts. Its characterization is essential to ensure process repeatability, optimize mechanical properties, and ensure compliance with standards. At the FILAB laboratory, we analyze the characteristics of metal powders to ensure their performance in metallurgy.
The size and shape of the particles determine the fluidity, density after compaction and mechanical properties of the parts. Using electron microscopy and particle size distribution analyses, we adjust these parameters to optimise sintering and 3D printing.
Impurities and undesirable reactions can compromise the quality of alloys. Our spectrometric analyses guarantee a composition that complies with requirements, avoiding structural defects and ensuring perfect suitability for industrial applications.
Apparent and compact density is controlled to limit porosity and defects, ensuring robust, homogeneous parts. Our humidity and oxidation tests enable us to anticipate the risks of degradation and optimise storage and processing.
Metal powders, particularly sensitive alloys such as titanium, require strict monitoring of their chemical reactivity. Our thermal analyses and fluidity tests enable us to adapt additive manufacturing parameters and ensure maximum safety.

FAQ
ISO 52907 defines the requirements and test methods for the characterization of metal powders used in additive manufacturing. It covers, in particular, the morphology, chemical composition, particle size distribution and physical properties of the powders.
Characterizing your powders allows you to:
- Guarantee the quality and traceability of your raw materials,
- Ensure regulatory and customer compliance,
- Optimize your additive manufacturing processes,
- Prevent non-conformities related to the mechanical properties of the parts produced.
The ISO 52907 standard primarily concerns additive manufacturing. It is particularly relevant to:
- aeronautics and space,
- medical and implantable devices,
- nuclear and energy,
- automotive and transportation,
- luxury and jewelry.
Particle size distribution (granulometry) is perhaps the most critical physical parameter.
- Average particle size: this must match the requirements of the AM system. LPBF systems often require fine powders (typically 15-60 µm).
- Fines (small particles): excess fines can impair flowability and absorb laser/beam energy, leading to porosity.
- Large particles: these can cause defects in the spread layers and create pores.
ISO 52907 recommends the use of laser diffraction as the standard method.
