Measurement uncertainty shall be estimated at the level of the parametric value, unless otherwise specified.

Values for trueness, precision and uncertainty of measurement are expressed in pH units.

If you have absolutely no control over the trend, yes.

The uncertainty of measurement should be estimated at the level of 3 mg/l of the total organic carbon (TOC).

Use of state-of-the-art specialised and universal measuring techniques to minimise measurement uncertainty

The uncertainty of the stress measurement calculated in part 3 is 6%.

The uncertainty of measurement should be estimated at the level of 1,0 NTU (nephelometric turbidity units) in accordance with EN ISO 7027.

The analytical result has to be reported as x +/– U whereby x is the analytical result and U is the measurement uncertainty.

Measurement uncertainty shall be estimated at the level of the parametric value, unless otherwise specified.

The performance criterion for measurement uncertainty (k = 2) is the percentage of the parametric value stated in the table or better.

Uncertainty of measurement is a non-negative parameter characterising the dispersion of the quantity values being attributed to a measurand, based on the information used.

Values for trueness, precision and uncertainty of measurement are expressed in pH units.

Values for trueness, precision and uncertainty of measurement are expressed in pH units.

The uncertainty of measurement should be estimated at the level of 3 mg/l of the total organic carbon (TOC).

High local velocities of the recirculating air, resulting variable static pressures on the engine and uncertainty in the thrust measurement are avoided.
