GB/T 26642-2022 is the Chinese standard "Non-destructive testing - Industrial computed radiography with storage phosphor imaging plates - General principles for testing of metallic materials using X-rays and gamma rays".
Its scope clause reads: This document specifies the basic techniques of computed radiography with a view to obtaining satisfactory results economically and reproducibly.
The technology to detect It is based on the basic theory of measurement and experimental measurement. This document specifies the use of industrial computer X and gamma rays that store phosphorescent imaging plates (IPs).
General rules for detection. This document is based on the basic principles of film-based radiographic inspection of metallic materials as defined in ISO 5579.
Basic setup of radiation sources, detectors and their corresponding geometrical positions in accordance with ISO 5579 and related product standards, such as welding seam standard ISO 17636 And casting standard EN12681 requirements.
This document does not prescribe missing acceptance clauses. Computed radiography (CR) systems provide computer-only viewing and evaluation Digital grayscale image.
This document establishes recommended principles for the selection of detectors and radiographic testing. Computers, software, monitors, printers and observation conditions and other important elements are not the main content of this document.
This document specifies the minimum requirements for computed radiography and digital images to obtain film-based radiographs as determined in accordance with ISO 5579 Photographic detection is equally lacking in detection sensitivity.
Some application standards, such as EN16407, provide inspections that may require different or less stringent requirements. test conditions.
