International acoustic emission standard analysis and development outlook

At present, the major acoustic emission (AE) standards in the world mainly consist of American, European, International Organization for Standardization (ISO) and Chinese standards. The status of the four groups of standards is analysed in this paper and compared based on quantity and type. A comparative analysis of the content of certain similar standards is carried out. Compared with ISO and European standards, the quantity of American and Chinese standards is larger due to the rapid conversion of new technologies into standards. European standards are well-principled and systematic and the general standards provide the basis for all AE testing and standard development. ISO standards, even when dealing in part with similar content, seek to be consistent with European and American standards, to have a distinct presentation of methodologies and to follow the principles of developing standards for new technologies. © 2020 British Institute of Non-Destructive Testing.
