It is also an important tool for product quality control and ensuring the safety of equipment and facilities. The main means of full operation, it also provides feedback on the production process. Non-destructive testing uses the properties of heat, force, sound, light, electricity, and magnetism of materials, 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, 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 Fields such as engineering, weapons, 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 "Terms of Non-destructive Testing" aims to establish The term generally applicable to standardized documents of non-destructive testing consists of eleven parts. ---12604.1 Non-destructive testing term Ultrasonic testing ---12604.2 Non-destructive testing terminology radiographic testing ---12604.3 Non-destructive testing terminology penetration testing ---12604.4 Non-destructive testing terminology Acoustic emission testing ---12604.5 Non-destructive testing terminology magnetic particle testing ---12604.6 Non-destructive testing terms Eddy current testing ---12604.7 Non-destructive testing terminology leak detection ---12604.8 Non-destructive testing terminology neutron testing ---12604.9 Non-destructive testing terminology infrared testing ---12604.10 Non-destructive testing terminology magnetic memory testing ---12604.11 Non-destructive testing terminology X-ray digital imaging testing This document is the seventh part of GB/T 12604, and it carries out leak detection terminology from the aspects of gas, detection technology and detection procedures. definition. This revision of GB/T 12604.7 focuses on the convergence with the international standard of leak detection terminology, and increases the coverage. The file structure has been adjusted so that there is a basis for formulating leak detection methods and product documentation, so as to give full play to the basic general support of the term file. Support functions to better promote non-destructive testing trade, exchanges and technical cooperation. Non-destructive testing terminology leak detection1 ScopeThis document defines terms related to leak detection. This document is applicable to leak detection related fields.2 Normative referencesThere are no normative references in this document.3 Terms and definitions3.1 Atomic/molecular structure 3.1.1 Concentration The ratio of the number of atoms or molecules of a certain component in the mixed gas to the total number of atoms or molecules of the mixed gas. Note 1.For an ideal gas (4.1.1), it is equal to the ratio of the partial pressure (3.2.2) to the total pressure. Note 2.In other cases, the concentration is mole fraction and the symbol is nB. 3.1.2 Ionization potential The minimum energy required to remove an electron from an atom or molecule to form a positive ion, expressed in electron volts. 3.2 Pressure and vacuum 3.2.1 Atmospheric pressure The pressure of the atmosphere at a specific place and time. 3.2.2 Partial pressure pA,pB The pressure generated when gas or steam exists alone in a closed container. 3.3 Gas/solid interaction 3.3.1 Gettering The removal of gas in a solid or internal cavity in a permanently bonded manner usually involves a chemical reaction. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 12604.7-2021_English be delivered?Answer: Upon your order, we will start to translate GB/T 12604.7-2021_English as soon as possible, and keep you informed of the progress.
