2.1 Measurement (result) (resultofa) measurement

Corresponding to a range of values \u200b\u200bto be measured.

Note 1. This term applies to the "uncertainty" approach.

Note 2. The center of the entire value of value deemed to be measured and used to describe the uncertainty of its dispersion characteristics.

Note 3. The measurement results are shown with the instrument, but also on calibration, calibration and use of the obtained model related.

Note 4. If the value of the series is compatible with all other measurements that are measured, then the value may indicate that the series of measured values.

Note 5. Family values, that uncertainty can only give a certain degree of confidence.

2.2 (Measurement) uncertainty uncertainty (ofmeasurement)

Measurements of the relevant parameters, represent reasonable given the discrete nature of the measured values.

Note 1. This term applies to the "uncertainty" approach.

Note 2. This parameter can be a deviation from the standard (or multiple) or half-width of the confidence interval.

Note 3. Measurement Uncertainty often made up of many components of the composition, some components may be statistical distribution of the results of a series of measurements to estimate that the standard deviation of test table

Said. Other statements may also be part of the standard deviation can be estimated from the distribution of experience or other information based on probability.

Note 4. All the components of the measurement results and uncertainty of the assessed value is measured, can be considered the best estimate of these components of uncertainty is caused by a regular Movies

Sound volume caused by, for example, calibration, reference standards and influencing dispersion device and other related components.

2.3 (Amount of) true value truevalue (ofaquantity)

Value consistent with the definition of particularly given amount.

Note 1. This term applies to the "true value" approach.

Note 2. This value is a measure to get through over the.

Note 3. The true value itself can not be determined.

2.4 Absolute error absoluteerror

Algebra indication and comparison value difference.

Note 1. This term applies to the "true value" approach.

Note 2. The value should be compared to the true value of the quantity, but the true value can not be determined, it is generally use conventional true value.

(Amount of) conventional true value conventionaltruevalue (ofaquantity)

Assigned a value based on a specific amount of the agreement, as uncertainty can be used for a given purpose.

Note 1. This term applies to the "uncertainty" approach.
