ASTM E3338

ASTM E3338 is the ASTM standard guide for assessing the size and shape of solid particles, liquid droplets, and gas bubbles as they move through a system using a dynamic imaging analyzer. It helps provide a consistent framework for capturing and interpreting particle and droplet characteristics in flowing conditions, which can be important for product evaluation, process control, and technical comparison. For users working with dynamic dispersions, this guide supports more repeatable measurement practices.

What is ASTM E3338?

This ASTM standard is a guide focused on dynamic imaging analysis of dispersed matter, including solid particles, liquid droplets, and gas bubbles. The title indicates its emphasis on size and shape measurements while the sample is being conveyed, rather than in a static state. ASTM E3338 is therefore relevant to users who need a structured approach to observing moving materials with an imaging-based instrument. It is commonly used as a technical reference for method selection, measurement consistency, and reporting practices.

Where is ASTM E3338 used?

ASTM E3338 is typically used in laboratory and process environments where dynamic imaging analyzers are applied to flowing suspensions, sprays, or other conveyed dispersions. It may support work involving materials that contain particles, droplets, or bubbles and where movement through a system affects what is measured. Because the guide addresses dynamic observation, it is especially useful in test setups and quality workflows that rely on imaging data for comparison, development, or routine evaluation.

Why is ASTM E3338 important?

This guide matters because measurements taken under dynamic conditions can vary with flow, concentration, and instrument setup. ASTM E3338 helps users apply a more consistent framework for evaluating size and shape, which supports better repeatability and clearer communication of results. In procurement, testing, and quality control settings, that consistency can reduce ambiguity and improve confidence in product assessment. For organizations using imaging-based analysis, ASTM E3338 can also help align internal practices with a recognized ASTM standard.
