ASTM E2387

ASTM E2387 is the ASTM standard for Standard Practice for Goniometric Optical Scatter Measurements, providing a structured approach for evaluating how light is scattered by a surface or material. It helps users apply a consistent measurement practice when comparing optical scatter results, supporting more reliable testing and documentation. For teams involved in optical characterization, this standard can improve consistency in measurement setup and interpretation while keeping the process aligned with a recognized technical reference.

ASTM E2387 standard overview

ASTM E2387 outlines a practice for goniometric optical scatter measurements, which generally means measuring scattered light at defined angles using a goniometric setup. The standard is intended to support repeatable optical scatter evaluation by giving users a common technical framework for collecting and reporting results. As an ASTM standard, it is useful when a product page or procurement process needs a clear reference for measurement practice, consistency, and comparison across test data.

Where is ASTM E2387 used?

This standard is commonly used in optical testing environments where scatter behavior needs to be measured in a controlled and repeatable way. It may be relevant for laboratories, quality control groups, and engineering teams working with surfaces, coatings, or other materials where light scatter is part of the performance assessment. ASTM E2387 is also useful when comparing results from different instruments or test setups that rely on goniometric measurements.

Practical importance of ASTM E2387

ASTM E2387 matters because optical scatter data can vary significantly without a consistent measurement practice. Using a recognized standard helps support more dependable results, clearer communication between suppliers and buyers, and better alignment in testing workflows. It may also reduce confusion during product evaluation by giving teams a common reference for how measurements are taken and reported. For organizations that rely on optical performance data, this can support quality control and compliance-related decisions.
