Foreword

The standard reference ASTME991.1998 "Standard method for measurement of fluorescent samples color" and ASTME991.2006 "with a monochrome Measurement of the fluorescence color sample standard method ", and ASTME991.1998 and ASTME991.2006 are non-degree of consistency Equivalent. This standard ASTME991.1998 main differences are as follows. --- Increasing the photoelectric integral measurement method; And ASTME991.2006 main differences are as follows. 1998 light consistency factor (SCF) of the definition and calculation; retain the use of SCF method sentence. --- ASTME991 Reserved Off the instrument light source and illuminant D65 consistent level of content. This standard replaces GB/T 9340-2001 "Relative fluorescence measurement sample color." This standard compared with GB/T 9340-2001 The main changes are as follows. --- Standard Chinese name was changed to "color sample fluorescence measurement method"; English name changed to "Methodsforcolormeas- urementoffluorescentspecimens "; --- Terms and definitions added "light consistency factor" to increase the "ultraviolet excitation fluorescence" in the definition of fluorescence, the "visible fluorescence excitation" Content; --- Edit "colorimeter Law" as "photoelectric integration", see Chapter 6; 5.2.4.2,5.2.4.3; --- Modify the original standard 5.1.3 source level; increase consistent with the SCF process method to determine the light source and instrument of standard illuminant D65 Degree, see 5.2.1; increase SCF calculation method, see Appendix A; --- 5.1.2 deletes the original standard, increasing standard colorimetric tristimulus values CIE1931 observer under the chromaticity coordinates and CIE whiteness meter Calculation formula, see equation (1), (3), (5), (6); calculating tristimulus values increased normalization coefficient k; --- Increasing the CIE standard illuminant D65 relative spectral power distribution, CIE1931 standard colorimetric observer color matching functions and color products Coordinate, CIE1964 standard colorimetric observer color matching functions and color coordinates, completely diffuse reflector in the CIE standard illuminant D65 Tristimulus values and chromaticity coordinates, and are shown in Table 1, Table 2, Table 3, Table 4. Appendix A of this standard is a normative appendix. The standard color by the National Standardization Technical Committee and centralized. This standard was drafted. China Institute of Metrology, Shenzhen Haichuan Color Technology Co., Ltd. The main drafters of this standard. Ma Yu, Wang Yu, Feng Guo Jin, Chen Ping, HE Wei-ping, Tang Hui Gong. This standard replaces the previous standard release case. This standard was first published in 1988, in June 2001 the first amendment. Fluorescent color sample measurement method

1 Scope

This standard specifies the color of fluorescent samples two measurement methods --- spectrum spectrophotometry, optical integration and measurement results indicate method. This standard applies to relative measurements in the visible region of the light emitting reflection fluorescence sample color. This standard does not apply to an electroluminescent samples, chemiluminescent sample and measuring the phosphorescent color sample; does not apply to chemical analysis applications Measuring fluorescence characteristics.

3 Terms and Definitions

GB/T 5698 and established the following terms and definitions apply to this standard. 3.1 Certain substances are or after exposure to radiation of a certain wavelength band, of the emitted light differs from the wavelength of irradiation, called fluorescence. Called UV fluorescence produced after absorbing ultraviolet radiation excited fluorescence; fluorescence produced after absorbing visible radiation known as visible fluorescence excitation. 3.2 After absorption of shortwave ultraviolet radiation in the visible region of the emitted fluorescence, thereby increasing a chemical visual whiteness of the material. 3.3 Samples for measuring fluorescence whiteness whiteness meter. Its main feature is to sample fluorescence measured under simulated standard illuminant D65 light source The whiteness. 3.4 For measuring the fluorescence color sample tristimulus values or chromaticity coordinates colorimeter. Its main feature is to simulate measured in standard illuminant Chroma value of fluorescent samples under D65 light source. 3.5 Relative spectral sampling hole measuring instrument lighting relative spectral irradiance distribution curve CIE standard lighting and specific body points Cloth curves square root of the variance. ......
