Introduction

This document is a revision of GA/T 1065-2013 "Specification for Calibration of Microdose X-ray Safety Inspection Equipment Test Body".

Because it is GB 15208.1-2018 "Microdose X-ray Safety Inspection Equipment Part 1: General Technical Requirements", GB 15208.2-2018 Micro-dose X-ray security inspection equipment Part 2: Transmission baggage security inspection equipment, GB 15208.3-2018 Micro-dose X-ray GB 15208.4-2018 "Micro-dose X-ray Security Inspection Equipment Part 3: Transmission Cargo Security Inspection Equipment" Equipment Part 4: Human body safety inspection equipment", GB 15208.5-2018 "Microdose X-ray safety inspection equipment Part 5: Back 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.
