The most direct and accessible methods for obtaining the color differences and color coordinates of object colors are by instrumental measurement using colorimeters or spectrophotometers with either hemispherical or bidirectional optical measuring systems. This test method provides procedures for such measurement by use of a colorimeter with either a bidirectional or a hemispherical optical measuring system. This test method is suitable for measurement of color differences of nonmetameric, nonparameric pairs of object-color specimens, or color coordinates of most such specimens. 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. For the measurement of retroreflective specimens by this test method, the use of bidirectional geometry is recommended (See Guide E179 and Practice E805). Note 38212;To ensure inter-instrument agreement in the measurement of retroreflective specimens, significantly tighter tolerances than those given in Practice E1164 in the section on Influx and Efflux Conditions for 45°:Normal (45:0) and Normal:45° (0:45) Reflectance Factor are required for the instrument angles of illumination and viewing. Information on the required tolerances is being developed. A requirement for the use of a colorimeter to obtain accurate color coordinates is that the combination of source, filter, and detector characteristics to duplicate accurately the combined characteristics of a CIE standard illuminant and observer. 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 4.2). For the measurement of small color differences between nonmetameric, nonparameric specimens, accuracy in absolute color coordinates is less important and standardization of the colorimeter by use of a white standard is satisfactory. However, accurate color-difference measurement requires that specimen pairs have similar spectral and geometric characteristics.1.1 This test method covers the instrumental measurement of specimens resulting in color coordinates and color difference values by using a tristimulus colorimeter, also known as a tristimulus filter colorimeter or a color-difference meter. 1.2 Provision is made in this test method for the measurement of color coordinates and color differences by reflected or transmitted light using either a hemispherical optical measuring system, such as an integrating sphere, or a bidirectional optical measuring system, such as annular, circumferential, or uniplanar 45:0 and 0:45 geometry. 1.3 Because of the limited absolute accuracy of tristimulus colorimeters, this test method specifies that, when color coordinates are required, the instrument be standardized by use of a standard having similar spectral (color) and geometric characteristics to those of the specimen. This standard is also known as a product standard. The use of a product standard of suitable stability is highly desirable. 1.4 Because tristimulus colorimeters do not provide any information about the reflectance or transmittance curves of the specimens, they cannot be used to gain any information about metamerism or paramerism. 1.5 Because of......

The rejection of materials due to color is a common and expensive occurrence, and it is useful for a customer and producer to set a color specification with an associated tolerance before the transaction. This guide discusses the concept and details the ASTM standards to be used in the process.1.1 This guide leads the user through the process for setting a color tolerance for a product or material. It points to the appropriate ASTM standards that affect each step of the process. It includes the discussion points on which the two parties must agree and provides caveats for various options selected.1.2 This guide does not suggest numerical values for tolerances. These values must be agreed upon by the two parties involved.This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

1.1 This practice provides a means of specifying the colors of objects in terms of the Munsell color order system, a system based on the color-perception attributes hue, lightness, and chroma. The practice is limited to opaque objects, such as painted surfaces viewed in daylight by an observer having normal color vision. This practice provides a simple visual method as an alternative to the more precise and more complex method based on spectrophotometry and the CIE system (see Practices E 308 and E 1164). Provision is made for conversion of CIE data to Munsell notation.This standard does not purport to address all of the safety concerns, if any, associated with its use.

All commercial reflectometers measure relative reflectance. The instrument reading is the reflectance factor, the ratio of the light reflected by a reference specimen to that reflected by a test specimen. That ratio is dependent on specific instrument parameters. National standardizing laboratories and some research laboratories measure reflectance on instruments calibrated from basic principles, thereby establishing a scale of absolute reflectance as described in CIE Publication No. 44 (2). These measurements are sufficiently difficult that they are usually left to laboratories that specialize in them. A standard that has been measured on an absolute scale could be used to transfer that scale to a reflectometer. While such procedures exist, the constraints placed on the mechanical properties restrict the suitability of some optical properties, especially those properties related to the geometric distribution of the reflected light. Thus, reflectance factor standards which are sufficiently rugged and able to be cleaned, depart considerably from the perfect diffuser in the geometric distribution of reflected radiance. The geometric distribution of reflected radiance from a pressed powder plaque is sufficiently diffuse to provide a dependable calibration of a directional-hemispherical reflectometer. Although pressed powder standards are subject to contamination and breakage, the directional-hemispherical reflectance factor of pressed powder standards can be sufficiently reproducible from specimen to specimen made from a given lot of powder, so as to allow one to assign absolute reflectance factor values to all the powder in a lot. This practice describes how to prepare white reflectance factor standards from a powder in a manner that allows a standardizing laboratory to assign the absolute scale of reflectance to the plaque.1.1 This practice covers procedures for preparing pressed powder transfer standards. These standards can be used in the near-ultraviolet, visible and near-infrared region of the electromagnetic spectrum. Procedures for calibrating the reflectance factor of materials on an absolute basis are contained in CIE Publication No. 44 (). Pressed powder standards are used as transfer standards for such calibrations because they have a high reflectance factor that is nearly constant with wavelength, and because the geometric distribution of reflected flux resembles that from the perfect reflecting diffuser.1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

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.1.6 This test method is generally suitable for any non-fluorescent, planar, object-color specimens of all gloss levels. 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.1.7 This test method does not apply to the use of a spectrocolorimeter, which is a spectrometer that provides colorimetric data, but not the underlying spectral data. Measurement by using a spectrocolorimeter is covered in Practice 1164 and methods on color measurement by spectrophotometry.This standard does not purport to address all of the safety concerns, if any, associated with its use.

In this standard chracteristics of appropriate materials and their use for calibration of the photometric scale in colorimetry and photometry are described. The definition of the photometric scale is typically based on a 2-point calibration. For this black and white standards of different shape and of small wave length dispersion are used. The scope of this standard is aimed at the application of all devices for colorimetry and photometers which are used for reflexion measuring.

1.1 This practice covers the calculation, from instrumentally measured color coordinates based on daylight illumination, of color tolerances and small color differences between opaque specimens such as painted panels, plastic plaques, or textile swatches. Where it is suspected that the specimens may be metameric, that is, possess different spectral curves though visually alike in color, Practice D 4086 should be used to verify instrumental results. The tolerances and differences determined by these procedures are expressed in terms of approximately uniform visual color perception in CIE 1976 CIELAB opponent-color space (), CMC tolerance units (), CIE94 tolerance units (), the DIN99 color difference formula given in DIN 6176 (), or the new CIEDE2000 color difference units ().1.2 For product specification, the purchaser and the seller shall agree upon the permissible color tolerance between test specimen and reference and the procedure for calculating the color tolerance. Each material and condition of use may require specific color tolerances because other appearance factors, (for example, specimen proximity, gloss, and texture), may affect the correlation between the magnitude of a measured color difference and its commercial acceptability.This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.

This practice should be used only to compare specimens of the same material and same general appearance. For example, a series of specimens to be compared should have generally similar gloss, texture, and (if not opaque) thickness, and translucency. For yellowness measurement, this practice is limited to specimens having dominant wavelength in the range 570 to 580 nm, or Munsell hue approximately 2.5GY to 2.5 Y. For whiteness measurement, this practice is limited to specimens having Munsell value greater than 8.3 (CIE Y greater than 65) and Munsell chroma no greater than 0.5 for B hues, 0.8 for Y hues, and 0.3 for all other hues (see 3.3.1). The combination of measurement and calculation leading to indices of yellowness or whiteness is a psychophysical process, that is, the procedures specified are designed to provide numbers correlating with visual estimates made under specified typical observing conditions. Because visual observing conditions can vary widely, users should compare calculated indices with visual estimates to ensure applicability. Some standards addressing the visual estimation of color and color difference are Practices D 1535, D 1729, E 1360, and E 1541, and Guide E 1499. This practice does not cover the preparation of specimens, a procedure that may affect significantly the quantities measured. In general, specimens should be prepared and presented for measurement in the manner that is standard for the test being performed. Select enough specimens or specimen areas to provide an average result that is representative of each sample to be tested. See Practice E 1345.1.1 This practice provides numbers that correlate with visual ratings of yellowness or whiteness of white and near-white or colorless object-color specimens, viewed in daylight by an observer with normal color vision. White textiles, paints, and plastics are a few of the materials that can be described by the indices of yellowness or whiteness calculated by this practice.1.2 For a complete analysis of object colors, by a specified observer and under a specified illuminant, use of three parameters is required. For near-white specimens, however, it is often useful to calculate single-number scales of yellowness or whiteness. This practice provides recommended equations for such scales and discusses their derivations and uses, and limits to their applicability (see also Ref ()).1.3 solely-SI-units;This standard does not purport to address all of the safety concerns, if any, associated with its use.
