DIN IEC 62709:2025-05

This document applies to security screening systems that utilize X-ray radiation and are used to inspect people who are not inside vehicles, containers, or enclosures. Specifically, this document applies to systems used to detect objects carried on or within the body of the individual being inspected. It specifies minimum performance for such systems, standard test procedures, and test objects for measuring the image quality of the systems. The standard makes reference to DIN IEC 62463 (VDE 0412-11): 2025-03, Radiation protection instrumentation - X-ray systems for the security screening of persons (IEC 62463:2024) with regard to electromagnetic compatibility as well as radiological, electrical, and mechanical safety. The standard differs from DIN IEC 62709 (VDE 0412-12):2015-06 as follows: a) clarified the test procedures to maintain consistency with IEC 62463; b) changed the term "spatial resolution" to "pentalith resolution"; c) modified some standard test conditions; d) modified some terms and definitions; e) changed the imaging requirements for transmission general-use systems. This standard applies to the following types of systems: - systems designated as mobile or fixed; - systems employing detection of primary radiation, backscattered radiation, forward-scattered radiation or some combination of these modalities to form two-dimensional X-ray images; - systems that are primarily imaging but that also may have complementary features such as material discrimination, automatic active or passive detection alerts. However, the standard does not address how to test these complementary features.
