For dated references, only the dated edition applies to this article Pieces. For undated references, the latest edition (including all modifications) applies to this document. Industrial Analysis of GB/T 212 Coal GB/T 214 Determination of total sulfur in coal Rules for the analysis of coal - General test methods Evaluation and Representation of Measurement Uncertainty in JJF1059.13 terms and definitionsThe following terms and definitions, as defined in GB/T 483 and JJF1059.1, apply to this document. For ease of use, repeat the following columns Some of the terms and definitions in GB/T 483 and JJF1059.1 are available. 3.1 Measured measurand The amount to be measured. [JJF1059.1-2012, definition 3.1] 3.2 Measurement result Together with other useful information, to give a set of measured values. [JJF1059.1-2012, definition 3.2] 3.3 Experimental standard deviation of experimentalstandarddeviation The measurement of the same measurement was carried out by n times to characterize the dispersion of the measurement results. With symbol s. Note 1. The experimental standard deviation s (xk) of a single measured value xk in n measurements can be calculated according to the Bessel formula. s (xk) = i = 1 (xi-x) 2 n-1 Where. xi --- the measured value of the first i; x - the arithmetic mean of a set of measured values obtained from n measurements; n - number of measurements. Note 2. The experimental standard deviation s (x) of the arithmetic mean x of n measurements is. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 33303-2016_English be delivered?Answer: Upon your order, we will start to translate GB/T 33303-2016_English as soon as possible, and keep you informed of the progress.
