3.1 Basic terms

311-01-01

Given a set of values \u200b\u200bto be measured. [!= Vp IM3.1]

Note 1. The term used for "uncertainty" approach.

Note 2. The center of this set of values \u200b\u200bis selected as the value of the measured values, and used to describe the uncertainty of their dispersion.

Note 3. The indicated value measurements and measuring instruments as well as calibrated correction amount and use a model to get about.

Note 4. If this set of values \u200b\u200bto be measured with the same measure is compatible with all other is that the set of values \u200b\u200bmay represent the value being measured.

Note 5. This group value and its uncertainty, is given only at a certain confidence level.

311-01-02

Associated with the measurement results of a parameter used to characterize reasonable given the dispersion of the measured values. [Vp IM3.9]

Note 1. The term used for "uncertainty" approach.

Note 2. This parameter can be a standard deviation (or a given multiple) or half the width of a given confidence interval. Defined in the GUM uncertainty obtained Different methods degrees.

Note 3. Measurement Uncertainty often made up of many components of the composition. Some components may be statistical distribution of a series of measurements to estimate and standard deviation Test table Shown. Other components may be used to estimate the probability of experience or other information based on the distribution, the standard deviation can also be expressed.

311-01-03

Specific quantity to be measured. [Vp IM2.6] 311-01-04 Consistent with the value assigned to a specific amount. [Vp IM1.19]

Note 1. The term used for "true value" approach.
