1 Scope

This verification system table is suitable for the verification of luminous intensity measuring instruments. It specifies the luminous intensity of candela (cd) The use of the national baseline, the full set of basic measuring instruments included in the baseline, the metrological parameters of the baseline, Sub-benchmark, working standards, standards to the work of measuring instruments transmitted luminous intensity unit of the program, indicating its uncertainty Degree and the basic test methods.

2 measurement standards

2.1 luminosity national benchmark 2.1.1 Photometric National Reference Used to reproduce the luminous intensity unit --- the amount of candela (cd), and through the luminous Degree of sub-benchmark, working standards to luminous intensity standard lamp, luminous intensity measuring instrument transmission unit volume to ensure that the national Uniformity of light value. The measured luminous intensity range of values (400 ~ 1200) cd. 2.1.2 luminosity National benchmark standard by a group of not less than 5 high stability conical compensated electrical calibration radiometer composition. 2.1.3 luminosity National benchmark recurrence luminous intensity unit of magnitude expansion uncertainty. U = 0.20%, k = 2. 2.1.4 Photometric National Reference Absolute irradiance measurements are transmitted to luminosity references on a photometric reference device. 2.1.5 Luminosity National benchmark to the luminous intensity of the benchmark reference value for the best measurement of capacity. U = 0.24%, k = 2. 2.2 luminosity national benchmarks 2.2.1 Photometric National Sub-benchmark Through the comparison with the luminosity national benchmark to determine the value, the measured luminous intensity value range Wai for the (400 ~ 1200) cd. 2.2.2 luminosity National Sub Reference Standards from a group of not less than 5 stable performance Cone cavity compensated type of electrical calibration Radiation Accounting composition. 2.2.3 luminosity national sub-benchmark recurrence luminous intensity unit value of the extended uncertainty. U = 0.22%, k = 2. 2.2.4 Photometric National Sub Reference Absolute radiative measurement is transmitted to the luminosity secondary reference on the photometric secondary reference device Magnitude. 2.2.5 Photometric States Sub-benchmark to the luminous intensity of the benchmark for the transfer of the best measurement of the amount of capacity as follows. U = 0.26%, k = 2. Note. Since.2003, the original "Metrology Verification System" collectively referred to as the "Metrology Verification System Table." 2.3 luminous intensity as a benchmark 2.3.1 luminous intensity of the reference for the preservation of luminous intensity of the unit value and international comparison, and through the work of all State delivers luminous intensity value. Its luminous intensity value range (90 ~ 1200) cd. 2.3.2 luminous intensity of the reference standard device by the distribution temperature of 2856K, 2353K two groups of high-stability luminous intensity Degree of sub-reference lamps, each lamp group of not less than 7 lights. 2.3.3 Luminous Intensity The extended uncertainty of the secondary datum is. U = 0.28%, k = 2.
