ASTM E1347

ASTM E1347 is a test method focused on color and color-difference measurement by tristimulus colorimetry. It provides a standardized way to evaluate visual color characteristics using instrument-based measurements, helping users compare samples more consistently. For organizations that need reliable color assessment in quality control, product matching, or specification verification, this standard supports clearer communication and more repeatable results across testing workflows.

What is ASTM E1347?

ASTM E1347, Standard Test Method for Color and Color-Difference Measurement by Tristimulus Colorimetry, describes a formal approach for measuring color using tristimulus principles. In practical terms, it helps translate perceived color into measurable values so samples can be compared with greater consistency. The standard is commonly used when color appearance needs to be checked against a reference, tracked over time, or evaluated as part of a technical specification. It is a useful ASTM standard for controlled color measurement and comparison.

Where is ASTM E1347 used?

This standard is typically used in settings where color accuracy and repeatability matter, especially in laboratory, production, and inspection workflows. It may be applied when testing finished goods, materials, or components that require color comparison against an approved standard or between batches. ASTM E1347 is also relevant in quality assurance programs that depend on instrument-based color measurement to support acceptance decisions, documentation, and consistency in routine evaluation.

Why is ASTM E1347 important?

ASTM E1347 helps reduce subjectivity in color evaluation by giving users a standardized measurement method. That can improve consistency across operators, instruments, and test locations, which is important for procurement, product approval, and quality control. When color or color difference affects appearance, compliance, or customer acceptance, a recognized test method supports more dependable results and can lower the risk of disputes or rework.
