1 Scope

GB/Z 41399-2022 is the Chinese national standard on non-destructive testing instruments - industrial digital x-ray imaging system, in the field of testing. The /Z suffix marks it as a guiding technical document: it does not prescribe requirements that can be certified against, but sets out the technique, the method or the state of the art that the standards bodies recommend following. It was issued on 15 April 2022 by the State Administration for Market Regulation; Standardization Administration of China. As a guiding technical document it carries no separate date of entry into force: it applies from publication. Classification: ICS 19.100, CCS N78. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the principles, technical requirements, test methods and signs of industrial X-ray digital imaging systems. This document applies to the production, use and debugging of industrial X-ray digital imaging systems (hereinafter referred to as systems).

3 Terms and Definitions

The terms and definitions defined in GB/T 12604.2 and GB/T 36015-2018 and the following terms and definitions apply to this document.

3.1 X-ray digital detector X-raydigitaldetector A device that receives X-rays and converts them into digital signals that can be processed by a computer.

4 Principles

The X-ray machine emits X-rays, penetrates the detected workpiece, and is received by the image detector system, and the image information is input through the acquisition and processing. After that, use computer software for image processing to improve the contrast and clarity of the image, and display the processed image. on the display. The schematic diagram is shown in Figure 1.

Note. The image detector system includes X-ray digital detectors, image intensifiers and other components.
