Remainder: 448 flacon
Catalog number: 3.05.02.01.0555
Application:
The standard sample is intended for the preparation of a chromium-cobalt chromaticity scale, calibration and calibration of photometric measuring instruments (SI) used to determine the chromaticity of aqueous solutions on the chromium-cobalt scale, monitoring the metrological characteristics of SI during their tests, including for the purpose of type approval, certification of measurement methods and control of the accuracy of the results of measurements of the chromaticity of water solutions according to the chromium-cobalt scale according to GOST 31868-2012.
CO can be used for verification of appropriate measuring instruments, provided that its metrological and technical characteristics meet the criteria established in the verification methods of the relevant measuring instruments.
Technical specifications:
- The chromaticity value (chrome-cobalt scale) is 500 degrees of chromaticity;
- The relative error of the certified CO value with a confidence probability of P = 0.95 is ± 1.5 % ;
- The relative extended uncertainty with a coverage factor of 2 is 1.5%.
The shelf life of a copy of CO is 2 years.
Basic equipment:
- A bottle containing 40 ml of solution - 1 pc.;
- Passport - 1 pc.
