1 Scope

This verification system table is suitable for the verification of illumination measurement instruments, which provides the use of the national standard of illumination The complete set of basic measuring instruments included, the metrological parameters of the reference, and the reference to the standard, standard of work, Work measuring instruments transmitted light intensity unit of the program, the basic test methods and uncertainty.

2 measurement standards

2.1 light national standards 2.1.1 Illumination The national reference is used to reproduce the magnitude of the illuminance unit, which is determined by the working standard of illumination, the standard illumination Meter, a light level and two standards, the value passed to all levels of light meter, in order to ensure the value of the national light value Unite. Illumination National benchmark recurrence range of illumination (10 ~ 3 × 103) lx. 2.1.2 Luminous intensity The national standard consists of the following measuring instruments. a group (not less than 7) luminous intensity of the reference lamp, The distribution temperature of 2856K; light measurement device. 2.1.3 Illumination The expanded national uncertainty U of the baseline is 0.34%, including the factor k = 2 (the same applies below). 2.1.4 Luminosity The national baseline value is passed from the luminosity national baseline and is measured using absolute radiometry Value calibration. 2.1.5 Illumination The best measurement capability of the national reference measuring device for transmitting the value is U = 0.21%. 2.2 light sub-benchmark 2.2.1 Illumination The national reference illumination value range (10 ~ 3 × 103) lx. 2.2.2 Luminosity The national benchmarks consist of the following measuring instruments. One set (not less than seven) Sub-standard of luminous intensity Light, the distribution temperature of 2856K; light measurement device. 2.2.3 Luminosity The national benchmark for the expansion of uncertainty U is 0.37%. 2.2.4 Illumination The best measurement capability of the national sub-standard measuring device for transmitting the value is U = 0.21%. 2.2.5 Lightness The national sub-benchmark's value is transmitted by the photometric country's sub-benchmark. 2.3 light intensity work benchmarks 2.3.1 Light intensity Working standard is used to test the first and second level of illumination standard, And calibrate the standard illuminance meter directly on the track. Light intensity working reference light intensity range (1 ~ 3 × 103) lx. 2.3.2 Working light illumination standards by the distribution of temperature of 2856K luminous intensity of the reference lamp and photometric measurement device Composition, the standard lamp size should not be less than two, each not less than 5 lights. Note. Since.2003, the original "Metrology Verification System" collectively referred to as the "Metrology Verification System Table." 2.3.3 Illumination The extended uncertainty U of the working reference is 0.40%. 2.3.4 Luminosity The benchmark for the use of the standard method of calibration by photometric photometer by the national benchmark or national deputy Quasi transfer. 2.3.5 Luminosity The best measurement capability for the reference measurement device to transfer volume values is U = 0.50%. ...
