Foreword

GB/T 33260 "Detection capability" is divided into the following parts.

Part 1. Terms and definitions;

Part 2. Method for determining the detection limit of linear calibration cases;

- Part 3. Method for determining the critical value of response variables without calibration data;

- Part 4. Comparison of minimum detectable values and given values;

Part 5. Method for determining the detection capability of linear and non - linear calibration cases.

This part is part 1 of GB/T 33260.

This part is drafted in accordance with the rules given in GB/T 1.1-2009.

This part uses the re-drafting method to modify ISO 11843-1.:1997, "Detection Capability Part 1. Terms and Definitions". versus ISO 11843-1.:1997, the main technical content changes as follows.

--- the vertical line in Figure 1 in the basic state and the actual state between the solid line into a dotted line;

--- the scope of the simplified, ISO 11843-1.:1997 in the scope of the text into the standard introduction;

- Define the concept of capability in ISO 11843-1.:1997 as standard Chapter 2, the terms and definitions as Chapter 3 content.

This part of the National Statistical Methods Applied Standardization Technical Committee (SAC/TC21) proposed and centralized.

Introduction

The general concept given in this section, the critical value of the response variable, the critical value of the net state variable, and the minimum detectable value of the net state variable (See 3.9 to 3.11) for a variety of situations, such as the presence or absence of a substance in the material, whether there is fuel in the sample or device, or Geometric deformation in distorted static systems.

The threshold can be obtained from the actual measurement sequence in order to evaluate the unknown state of the system in this sequence, whereas the minimum of the net state variables the detected value as a characteristic value of the measurement method is used to select the appropriate measurement process. To characterize a measurement process, a laboratory or a measurement method, if each correlation level (ie, a measurement sequence, measurement process, laboratory or measurement method) has Appropriate measurement data, you can determine the minimum detectable value. Different measurement sequence, measurement process, laboratory or measurement method of the smallest detectable the value is different.

This part is suitable for continuous measurement of continuous scale and is suitable for the detection process and the detection capability of various measuring devices.

The relationship between the expected value of the response variable and the state variable value can be described by the calibration function. If the response variable or state variable is a vector Value, then this part can be applied to the vector component or component function.

There may be some differences between the terms used in the chemical analysis and the terms in this section. Appendix A gives the general terms and chemical the correspondence between the terms used.
