Full title and description

St ISO 13322-1-2014 — Particle size analysis — Image analysis methods — Part 1: Static image analysis methods. This international standard specifies requirements and recommendations for performing particle size analysis using static (fixed-sample) digital image capture and analysis, including image capture preparation, image quality, segmentation/counting procedures and reporting of results for particles that are stationary relative to the imaging system.

Abstract

ISO 13322-1:2014 covers the analysis of digital images (light or electron based) for determining particle size distributions where particles are fixed or otherwise stationary in the object plane. It focuses on static image analysis methods using full pixel-based evaluation, addressing sample and image preparation, counting and sizing procedures, calibration, traceability and reporting to achieve reproducible particle size distributions.

Scope

The standard applies to image-based methods used to determine particle size distributions from static images where particle motion relative to the optical axis is zero. It is applicable to digital images produced by light or electron imaging systems and covers requirements for sample presentation, image capture, image quality (including pixels-per-particle considerations), image segmentation, counting procedures, measurement reporting and calibration/traceability. The standard is intended for cases where images can be captured and analysed without motion-induced artefacts.

Key topics and requirements

• Definitions and symbols for image-based particle sizing (terminology and measurement descriptors).
• Sample preparation and distribution requirements (splitting, touching particles, suspending fluids).
• Image capture quality criteria, including recommended pixels-per-particle and magnification choices to meet accuracy needs.
• Image segmentation and contour detection methods (thresholding, edge detection) and procedures for handling touching or edge-cut particles.
• Counting procedures, size class grouping (linear or logarithmic), and calculation of particle size distributions.
• Calibration, traceability and recommendations for use of reference materials and instrument qualification/acceptance tests.
• Reporting and documentation requirements, including test report content and measurement uncertainty considerations.

Typical use and users

ISO 13322-1:2014 is used by analytical laboratories, research and development organizations, quality control teams and instrument manufacturers performing static image-based particle sizing for powders, suspensions and particulate materials. Typical users include laboratory analysts, microscopy specialists, QA/QC managers and equipment vendors implementing or validating image-analysis workflows and calibrations.

Related standards

Standards commonly referenced alongside ISO 13322-1 include ISO 13322-2 (dynamic image analysis methods), ISO 9276 series (representation and calculations for particle size results), and other sampling or method standards such as ISO 14488 and ISO 14887 for sampling and sample preparation. These related documents support consistent reporting, calculation and sampling practices for particle size analysis.
