Application:
The standard sample is intended for certification of measurement methods and control of accuracy of measurement results of the mass fraction of water in oil and petroleum products.
CO can be used for verification and calibration of appropriate measuring instruments, provided that its metrological and technical characteristics meet the criteria established in the methods of verification and calibration of appropriate measuring instruments.
Technical specifications:
- The certified CO value is 1.50% of the mass fraction of water;
- The range of certified values is 1.35-1.65% of the mass fraction of water;
- The relative error at P = 0.95 is ± 4%.
The shelf life of CO copies is 2 years.
Basic equipment:
- A bottle containing 100 ml of solution - 1 pc.;
- Passport - 1 pc.
