ASTM E805

ASTM E805 is a technical standard that helps users identify instrumental methods for measuring color and color difference in materials. By focusing on method identification rather than a single test procedure, it supports clearer selection and comparison of color measurement approaches. That makes it useful for quality control, product evaluation, and communication between suppliers and buyers when consistent color assessment matters. ASTM E805 is especially relevant where instrumental results must be understood and applied consistently.

What is ASTM E805?

ASTM E805, titled Standard Practice for Identification of Instrumental Methods of Color or Color-Difference Measurement of Materials, provides a structured way to recognize and distinguish instrumental approaches used in color evaluation. The standard is intended to support consistent terminology and method selection when measuring color or color difference. In practice, it helps users align measurement methods with the material being assessed and the reporting needs of a technical or commercial workflow. ASTM E805 is a useful reference for organizing color measurement practices.

Where is ASTM E805 used?

This standard is commonly used in laboratories, production environments, and quality assurance settings where instrumental color measurement is part of routine evaluation. It may be applied to materials and products that require color control, specification matching, or comparison across batches. ASTM E805 is relevant wherever users need to identify the appropriate instrumental method for assessing color or color difference and document results in a consistent, repeatable way. It supports practical decision-making in testing and inspection workflows.

Why is ASTM E805 important?

ASTM E805 matters because color measurement can vary depending on the instrument method used, and that variation can affect compliance, purchasing decisions, and product consistency. A clear framework for identifying methods helps reduce confusion and improves communication across testing, engineering, and supply-chain teams. For organizations that rely on instrumental color data, ASTM E805 supports more reliable comparisons, better quality control, and lower risk of misinterpretation when evaluating materials against a color requirement.
