Note. 1 This parameter can be such as the standard deviation (or multiples thereof), or the half-width of the confidence interval. 2 Measurement uncertainty consists of multiple components. Some of these components can be estimated using the statistical distribution of measurement column results and used in practice Test standard deviation characterization. Other components are estimated on the assumption of probability distribution based on experience or other information, and standard deviation Characterization.3 The measurement results should be understood as the best estimate of the value being measured and all the components of the uncertainty contribute to the dispersibility includingThose components introduced by the system effects, such as corrections and reference measurement standards. 3.2 standard uncertainty u (xi) standarduncertainty ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of JJF 1135-2005_English be delivered?Answer: Upon your order, we will start to translate JJF 1135-2005_English as soon as possible, and keep you informed of the progress.
