What is ISO-TS 18268:2017?

ISO-TS 18268:2017 is a technical specification developed by the International Organization for Standardization (ISO) that provides guidelines and requirements for the determination of particle size distributions in metal powders using laser diffraction. This standard aims to ensure accuracy and consistency in measuring particle sizes, which is crucial for various industries such as manufacturing, aerospace, and automotive.

The Importance of Particle Size Distribution

Particle size distribution plays a significant role in determining the properties and behavior of metal powders. It affects their flowability, packing density, surface area, and reactivity. Therefore, accurate measurement and control of particle size distribution are critical for achieving desired outcomes in powder metallurgy processes like sintering, compaction, and coating.

Laser Diffraction Technique in ISO-TS 18268:2017

ISO-TS 18268:2017 specifically focuses on the application of the laser diffraction technique for analyzing particle size distributions in metal powders. Laser diffraction is a widely used method due to its fast analysis time, non-destructive nature, and ability to provide reliable results over a broad range of particle sizes.

The standard outlines the instrument requirements, calibration procedures, sample preparation guidelines, measurement parameters, and data analysis techniques to be followed when using laser diffraction. It also covers the calculations necessary to obtain accurate particle size distribution data.

Benefits and Applications of ISO-TS 18268:2017

Implementing ISO-TS 18268:2017 offers several benefits to both manufacturers and end-users. Firstly, it enhances product quality by ensuring consistent and precise measurement of metal powder particle size distributions, leading to better process control and final product performance.

Secondly, having standardized methods for particle size analysis promotes comparability of results across different laboratories and manufacturers. This enables efficient collaboration, problem-solving, and knowledge exchange within the industry.

Lastly, ISO-TS 18268:2017 has widespread applications in various industries reliant on metal powders, such as additive manufacturing, powder metallurgy, coatings, and catalyst production. It allows companies to comply with quality standards and regulatory requirements while achieving efficient and cost-effective production processes.
