Standard Test Method for Minimum Resolvable Temperature Difference for Thermal Imaging Systems

ASTM E1347-97 用三色(滤色器)比色法进行颜色和色差测量的试验方法

1.1 This test method describes the instrumental measurement of color coordinates and color differences by using a tristimulus (filter) colorimeter, also known as a color-difference meter. This test method does not apply to the use of a spectrocolorimeter, which is a spectrophotometer that is normally capable of producing as output colorimetric data, but not the underlying spectral data from which color coordinates are calculated. Measurement by using a spectrocolorimeter is covered in Practice E1164 and methods on color measurement by spectrophotometry. 1.2 Provision is made in this test method for the measurement of color coordinates and color differences by reflected 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 or 0/45 geometry. Provision is also made for measurement by transmitted light using a hemispherical optical measuring system. 1.3 Because of the limited absolute accuracy of tristimulus (filter) colorimeters, this test method specifies that, when color coordinates are required, the instrument be calibrated by use of a standard having similar spectral (color) and geometric characteristics to those of the specimen. The use of a product standard of suitable stability is highly desirable. 1.4 Because of the inability of tristimulus (filter) colorimeters to detect metamerism or paramerism, or to correctly measure metameric or parameric pairs of specimens, this test method specifies that, when color differences are required, the two specimens must have similar spectral (color) and geometric characteristics. In this case, the instrument may be calibrated for reflectance measurement by use of a white reflectance standard or, for transmittance measurement, with no specimen or standard at the specimen position. 1.5 While this test method is generally suitable for all object-color specimens, it should not be used without observing certain restrictions on the geometries and calibration procedures appropriate for different types of specimens and uses, and on the spectral character (metamerism or paramerism) of specimens and standards. 1.6 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.

However, it should not be used for retroreflective specimens or for fluorescent specimens when highest accuracy is desired. Specimens having intermediate-gloss surfaces should preferably not be measured by use of this geometry.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

Standard Practice for Obtaining Spectroradiometric Data from Radiant Sources for Colorimetry

ASTM D1729-96(2003) 不透明材料色差的目测评估的标准操作规程

Although color measuring instruments are widely used, color matches are usually checked visually. The standardization of visual examination has greatly improved the uniformity of products and the accuracy of color matches. The use of this practice is essential for critical color matching but is also recommended for any color appraisal, such as the choice or approval of a color. This practice is widely used in industry to choose colors, exhibit colors reproducibly, inspect incoming materials, monitor color producing processes, and inspect finished goods. Visual appraisal is particularly important when the product inspected is not of the same material as the color standard to which it is compared. 4.2.1 Observers8212;This practice is based on the fundamental assumption that the observer has normal color vision and is trained and experienced in observing and classifying color differences. The significance of the results depends on that being so. The selection, evaluation, and training of observers are treated in Guide E 1499. 4.2.2 Illumination8212;Simulated average daylight is recommended by the International Commission on Illumination (CIE), but a slightly bluer simulated north-sky daylight came into widespread use in North America, because it provides a slightly greater distinction between very pale yellow and white, a distinction of great commercial importance.1.1 This practice specifies the equipment and procedures for visual appraisal of the colors and color differences of opaque materials that are diffusely illuminated.

ASTM E1336-96(2003) 用辐射分光法从视频显示单元中获取比色数据试验方法

The most fundamental method for obtaining CIE tristimulus values or other color coordinates for describing the colors of visual display units (VDUs) is by the use of spectroradiometric data. (See CIE No. 18 and 63.) These data are used by summation together with numerical values representing the 1931 CIE Standard Observer and normalized to Km, the maximum spectral luminous efficacy function. The special requirements for characterizing VDUs possessing narrow or discontinuous spectra are presented and discussed. Modifications to the requirements of Practice E 308 are given to correct for the unusual nature of narrow or discontinuous sources.1.1 This test method prescribes the instrumental measurements required for characterizing the color and brightness of VDUs.1.2 This test method is specific in scope rather than general as to type of instrument and object.1.3 The values stated in SI units are to be regarded as the standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.

ASTM E972-96(2013) 用阳光对薄板材料的太阳能光度透设比的测试方法

5.1 Glazed apertures in buildings are generally utilized for the controlled admission of both light and solar radiant heat energy into the structure. Other devices may also be used to reflect light and solar radiant heat into a building. 5.2 The bulk of the solar radiant energy entering a building in this manner possesses wavelengths that lie from 300 to 2500 nm (3000 to 25 000 Å). Only the portion from 380 to 760 nm (3800 to 7600 Å) is visible radiation, however. In daylighting applications, it is therefore important to distinguish the radiant (solar radiant energy) transmittance or reflectance of these materials from their luminous (light) transmittance or reflectance. 5.3 For comparisons of the energy and illumination performances of building fenestration systems it is important that the calculation or measurement, or both, of solar radiant and luminous transmittance and reflectance of materials used in fenestration systems use the same incident solar spectral distribution. 5.4 Solar luminous transmittance and reflectance are important properties in describing the performance of components of solar illumination systems including windows, clerestories, skylights, shading and reflecting devices, and other passive fenestrations that permit the passage of daylight as well as solar radiant heat energy into buildings. 5.5 This test method is useful for determining the solar luminous transmittance and reflectance of optically inhomogeneous sheet materials and diffusely reflecting materials used in natural lighting systems that are used alone or in conjunction with passive or active solar heating systems, or both. This test method provides a means of measuring solar luminous transmittance under fixed conditions of incidence and viewing. This test method has been found practical for both transparent and translucent materials as well as for those with transmittances reduced by reflective coatings. This test method is particularly applicable to the measurement of luminous transmittance of inhomogeneous, fiber reinforced, patterned, corrugated, or otherwise optically inhomogeneous materials when the transmittance is averaged over an area that is large in comparison to the inhomogeneities. 1.1 This test method covers the measurement of solar photometric transmittance of materials in sheet form.
