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

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Provision is also made for measurement by transmitted light using a hemispherical optical measuring system. Users must determine whether an instrument complying with this method yields results that are useful to evaluate and characterize retroreflective specimens, or specimens having optical structures.

Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.

This standard is also known as a product standard. 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. Users must determine whether an instrument complying with this method yields results that are useful to evaluate and characterize retroreflective specimens, or specimens having optical structures.

Due to copyright restrictions, we are not able to provide copies of standards.

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. This standard is also known as a product standard.

Standards can be obtained from appropriate standards authorities. 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. astmm

It is the responsibility of the user of this standard to astj appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Active view current version of standard. Typically a 50 mm 2″ or mm 4″ disk Data: Visual color and spectrophotometer readings can also be affected by surface texture, molding parameters, processing method, and viewing light sources.

Operation and Software Training – Measure samples and standards by single and average readings – Save, recall and delete measurements – Change illuminants, observers, color scales – Direct data transfer to Excel Geometry: Color analysis can be used to match axtm parts molded from different materials, or to evaluate color change due to outdoor exposure. The use of a product standard of suitable stability is highly desirable. This test method provides procedures for such measurement by use of a colorimeter with either a e147 or a hemispherical optical measuring system.

The use of a product standard of suitable stability is highly desirable. Measurement by using a spectrocolorimeter is covered in Practice E and methods on color measurement by spectrophotometry. 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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

What are your requirements. Asmt specifying the illuminant, observer angle, and the reference color, the test sample is inserted into the specimen holder and the spectrophotometer takes the reading.

What is your application? Measurement by using a spectrocolorimeter is covered in Practice E and methods on color measurement by spectrophotometry. Inspection Validating the specifications, value and safety of your raw materials, products and assets. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

However, accurate color-difference measurement requires that specimen pairs have similar spectral and geometric characteristics. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

General Use laboratory f1347 balances, baths, blenders, centrifuges, chart recorders, freezers, fume hoods, furnaces, glassware washers, glove boxes, mixers, moisture testing, ovens, pumps, shakers, vacuum equipment, water purification Active view current version of standard. The use of a product standard of suitable stability is highly desirable. Color Theory – The building blocks of color: For the measurement of small color differences between nonmetameric, nonparameric specimens, accuracy in qstm color coordinates is less important and standardization of the colorimeter by use of a white standard is satisfactory.

Measurement by using a spectrocolorimeter is covered in Practice and methods on color measurement by spectrophotometry. Type text as it appears:: Information on the required tolerances is being developed.
