GB/T 33260.2-2018 is the English-translated version of 检出能力第2部分：线性校准情形检出限的确定方法.

GB/T 33260.2-2018 is the Chinese standard "Capability of detection -- Part 2: Methodology in the linear calibration case".

Its scope clause reads: This part of GB/T 33260 specifies. --- Experiments for estimating the critical value of the net state variable, the critical value of the response variable, and the minimum detectable value of the net state variable design. --- If the calibration function is linear and the standard deviation is a constant or it is linear with the net state variable, the experimental data obtained is used.

The above three feature quantities are estimated. The method described in this section can be applied to various situations, such as checking the presence of a specific substance in a material, and the sample or device There is no energy release, or there is a geometric deformation of the static system under the action of torsion.

1 Scope

This part of GB/T 33260 specifies.

--- Experiments for estimating the critical value of the net state variable, the critical value of the response variable, and the minimum detectable value of the net state variable design.

--- If the calibration function is linear and the standard deviation is a constant or it is linear with the net state variable, the experimental data obtained is used.

The above three feature quantities are estimated.

The method described in this section can be applied to various situations, such as checking the presence of a specific substance in a material, and the sample or device

There is no energy release, or there is a geometric deformation of the static system under the action of torsion.

The critical value can be derived from the actual measurement sequence to evaluate the unknown state of the system represented by the measurement sequence, and the minimum of the net state variable

The detectable value is used as a feature of the measurement method to select the appropriate measurement process. In order to characterize a measurement process, a laboratory

Or the detection capability of a measurement method, if every relevant level (ie a measurement sequence, measurement process, laboratory or measurement method)

For the appropriate measurement data, determine the minimum detectable value. Minimal detectability of different measurement sequences, measurement processes, laboratories or measurement methods

The value is different.

GB/T 33260 is suitable for quantitative measurements at continuous scales and is applicable to the acquisition of detection capabilities of measurement processes and various measuring devices.

The functional relationship between the expected value of the response variable of the measuring device and the state variable value can be described by the calibration function. If the response variable or state variable

Is a vector value, this part can be applied to the vector component or component function.
