Foreword
GB/T 14480 "Non-destructive testing equipment Eddy current testing equipment" is divided into the following three parts:
---Part 1: Instrument performance and inspection;
---Part 2: Probe performance and inspection;
---Part 3: System performance and inspection:
This part is Part 3 of GB/T 14480:
This section was drafted in accordance with the rules given in GB/T 1:1-2009:
This part replaces GB/T 14480:3-2008 "Non-destructive testing eddy current testing equipment Part 3: System performance and inspection", and
Compared with GB/T 14480:3-2008, the main technical changes are as follows:
---Added the title "General Rules" (see 5:1);
---Modified the inspection level, inspection procedures, corrective measures, etc: (see 5:2, 5:3, 5:4, 5:1, 5:2, 5:3 of the:2008 edition);
---Modified the content in the implementation of the function test (see Chapter 6, Chapter 6 of the:2008 edition):
The translation method used in this part is equivalent to ISO 15548-3:2008 "Non-destructive testing eddy current testing equipment-Part 3: System performance and
test":
This section has made the following editorial changes:
--- Modify the standard name to "Non-destructive testing equipment Eddy current testing equipment Part 3: System performance and inspection":

Part 3: System performance and inspection
1 Scope
This part of GB/T 14480 specifies the performance of the general eddy current testing system and its test and inspection methods:
Through system performance evaluation, accurate characterization and comparability of eddy current testing equipment performance can be obtained:
By selecting system performance, a consistent and effective eddy current testing system can be designed for specific testing activities:
The auxiliary equipment used shall be characterized by the principles of this section:
This section does not give performance inspection indicators and inspection scope, these contents are given by the application file:
2 Normative references
The following documents are indispensable for the application of this document: For dated reference documents, only the dated version applies to this article
Pieces: For undated references, the latest version (including all amendments) applies to this document:
ISO 12718 Non-destructive testing Eddy current testing vocabulary (Non-destructive testing-Eddycurrent testing-Ter-
minology)
3 Terms and definitions
The terms and definitions defined in ISO 12718 apply to this document:
4 System performance
4:1 General performance
Eddy current testing systems are used to inspect specific products or make specific measurements, and the eddy current testing technology used should be specified: Eddy current testing system
The system includes instruments, connectors (such as connecting cables, slip rings, etc:), probe components, mechanical devices, auxiliary equipment and reference test pieces:
The general performance of the system includes:
a) Physical properties:
---Detection speed;
---Scan path;
---Mechanical arrangement and setting, as well as the relationship between the two and the tested product:
b) Performance related to calibration:
---Response characteristics to the reference test block;
---Response characteristics related to derived parameters such as coating thickness and crack depth of the tested product:
c) Functional characteristics:
---Set up instruments and auxiliary equipment through buttons or on the display;
---The initial state and equilibrium state of the complex plane display;
---Test the dynamic range of the system amplitude and phase:
