The revised version of the document GA/T 1065-2013 "Microdose X-ray Inspection Equipment" was released on December 1,.2019.
The metrological performance requirements of the "Standard for the Calibration of Test Bodies for Online Safety Inspection Equipment" cannot meet the requirements of the current micro-dose X-ray safety inspection equipment test bodies.
Calibration requirements.
This document covers the micro-dose X-ray security inspection equipment, including the transmission type baggage security inspection equipment, transmission type cargo security inspection equipment
All test objects in equipment, human body security inspection equipment, and backscatter object security inspection equipment clearly stipulate micro-dose X-ray security inspection
The purpose of the calibration requirements for equipment test bodies is to standardize the calibration work of micro-dose X-ray safety inspection equipment test bodies.
This document provides guidance for the processing and quality assessment of micro-dose X-ray safety inspection equipment test bodies and establishes the
Operability and traceability of calibration work of line safety inspection equipment test body.
