Scope
GB/T 33260.3-2018 is the English-translated version of 检出能力 第3部分：无校准数据情形响应变量临界值的确定方法.
GB/T 33260.3-2018 is the Chinese standard "Capability of detection -- Part 3: Methodology for determination of the critical value for the response variable when no calibration data are used".
Its scope clause reads: This part of GB/T 33260 specifies the specific situation where the value of the net state variable is zero (see 5.1). Repeated observations in the reference state are used.
The method of estimating the critical value of the response variable by means of the mean and standard deviation, from which the actual state (or sample to be tested) can be determined.
The value of the response variable is Nothing exceeds the critical value provided by the reference state. GB/T 33260.2-2018 specifies the threshold for determining the response variable, the critical value of the net state variable, and the minimum of the net state variable.
The general method of calculating the detected value. These methods are suitable for linear functions where there is a linear calibration, a standard deviation of the residual error is a constant, or a net state variable.
Situation. This section specifies how to determine the critical value of the response variable when there is no calibration data. Assume that the data is normally distributed or approximated Normal distribution.
The methods given in this section are used to obtain a large number of basic states but it is difficult to obtain a large number of actual states. Its clauses include terms and definitions.

1 Scope
This part of GB/T 33260 specifies the specific situation where the value of the net state variable is zero (see 5.1). Repeated observations in the reference state are used.
The method of estimating the critical value of the response variable by means of the mean and standard deviation, from which the actual state (or sample to be tested) can be determined. The value of the response variable is
Nothing exceeds the critical value provided by the reference state.
GB/T 33260.2-2018 specifies the threshold for determining the response variable, the critical value of the net state variable, and the minimum of the net state variable.
The general method of calculating the detected value. These methods are suitable for linear functions where there is a linear calibration, a standard deviation of the residual error is a constant, or a net state variable.
Situation. This section specifies how to determine the critical value of the response variable when there is no calibration data. Assume that the data is normally distributed or approximated
Normal distribution.
The methods given in this section are used to obtain a large number of basic states but it is difficult to obtain a large number of actual states.
