Introduction

Non-destructive testing technology is an indispensable tool for human industrialization and social development. It is also an important tool for product quality control and ensuring the safety of equipment and facilities.

The main means of full operation, but also feedback on the production process. Non-destructive testing uses the properties of heat, force, sound, light, electricity, and magnetism of materials to

Detect, locate and measure defects or abnormalities in materials and parts in a way that does not impair the expected performance and reliability, and evaluate their performance and composition.

Organization and integrity. The application of non-destructive testing covers machinery manufacturing, chemical industry, medicine and medical treatment, energy, transportation, metallurgy, construction, water conservancy, ocean engineering,

Weaponry, aviation, aerospace, nuclear industry, sanitary food, smuggling and anti-terrorism, and public security.

There are many methods and techniques of non-destructive testing, and it has a wide range of applications. The general terminology that establishes the basis of various methods and technologies of non-destructive testing is

The primary task of various non-destructive testing standardization organizations at home and abroad to develop non-destructive testing standardization activities. GB/T 12604 "Non-destructive testing technique

"Language" is the basic and universal standard that guides my country's non-destructive testing standardization activities. GB/T 12604 aims to establish universally applicable

The terminology for testing standardized documents consists of 11 parts.

---GB/T 12604.1 Non-destructive testing term Ultrasonic testing;

---GB/T 12604.2 Non-destructive testing term radiographic testing;

---GB/T 12604.3 Non-destructive testing terminology penetration testing;

---GB/T 12604.4 Non-destructive testing term Acoustic emission testing;

---GB/T 12604.5 Non-destructive testing terminology magnetic particle testing;

---GB/T 12604.6 Non-destructive testing term Eddy current testing;

---GB/T 12604.7 Non-destructive testing term leak detection;

---GB/T 12604.8 Non-destructive testing term neutron testing;

---GB/T 12604.9 terminology for non-destructive testing, infrared thermal imaging;

---GB/T 12604.10 Non-destructive testing terminology magnetic memory testing;

---GB/T 12604.11 Non-destructive testing terminology X-ray digital imaging testing.

This document is Part 6 of GB/T 12604, which covers eddy current testing from the aspects of general purpose, measurement, probe, instrument, application and evaluation.

Definition of terms. This revision of GB/T 12604.6 focuses on the connection with the international standard of eddy current testing terminology, and clarifies the eddy current

Testing terminology, the file structure is adjusted, so that there is a basis for formulating eddy current testing methods and product documents, so as to give play to the basis of terminology documents.

This universal support function can better promote non-destructive testing trade, communication and technical cooperation.
