When this requirement is not met, this test method requires the use of local standards for improving accuracy in the measurement of color coordinates see also 4.

Color analysis can be used to match adjacent parts molded from different materials, or to evaluate color change due to outdoor exposure. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Hunter Lab and XYZ are standard three dimensional color spaces that allows a precise definition of the color of a test sample.

Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Provision is also made for measurement by transmitted light using a hemispherical optical measuring system.

However, accurate color-difference measurement requires that specimen pairs have similar spectral and geometric characteristics. This standard is also known as a product standard. The use of a product standard of suitable qstm is highly desirable.

Assurance Testing Inspection Certification. In this case, the instrument may be standardized for reflectance measurement by use of a white reflectance standard or, for transmittance measurement, with no specimen or standard at the specimen position.

Standard Test Method for Color and Color-Difference Measurement by Tristimulus Colorimetry

A further limitation to the use of colorimeters having hemispherical geometry is the existence of a chromatic integrating-sphere error that prevents accurate measurement of color coordinates when the colorimeter is standardized by use of a white standard. After specifying the illuminant, observer angle, and the reference color, the test sample is inserted into the specimen holder and the spectrophotometer takes the reading.
