IEC TR 60601-4-5:2021 provides detailed technical specifications for SECURITY features of MEDICAL DEVICES used in MEDICAL IT-NETWORKS. MEDICAL DEVICES dealt with in this document include MEDICAL ELECTRICAL EQUIPMENT, MEDICAL ELECTRICAL SYSTEMS and MEDICAL DEVICE SOFTWARE. MEDICAL DEVICE SOFTWARE, although not in the scope of IEC 60601 (all parts), can also make use of this document. Based on the seven foundational requirements described in the state-of-the-art document IEC TS 62443 1 1:2009, this document provides specifications for different MEDICAL DEVICE capability SECURITY LEVELS (SL C). The specified SECURITY capabilities of a MEDICAL DEVICE can be used by various members of the medical community to integrate the device correctly into defined SECURITY ZONES and CONDUITS of a MEDICAL IT-NETWORK with an appropriate MEDICAL IT NETWORK's target SECURITY LEVEL (SL T).
This document is applicable to MEDICAL DEVICES with external data interface(s), for example when connected to a MEDICAL IT-NETWORK or when a human interface is used for processing – e.g. entering, capturing or viewing – CONFIDENTIAL DATA.
This document does not apply to other software used on a MEDICAL IT-NETWORK which does not meet the definition of MEDICAL DEVICE SOFTWARE.

b) LINE SPREAD FUNCTIONS;
c) one-dimensional MODULATION TRANSFER FUNCTIONS;
d) FOCAL SPOT PINHOLE RADIOGRAMS,
and the means for indicating compliance.
In informative annexes, STAR PATTERN imaging and BLOOMING VALUE are described.
IEC 60336:2020 cancels and replaces the fourth edition published in 2005. This edition constitutes a technical revision.
The significant changes of this fifth edition with respect to the previous edition are detailed in Clause E.6. These changes are:
a) introduction of digital detectors and discretization errors;
b) fewer normative requirements;
c) support for both SLIT CAMERA and PINHOLE CAMERA;
d) reintroduction of distorted (skewed) FOCAL SPOT;
e) keeping of STAR PATTERNS and BLOOMING VALUE as informative.

IEC 60522-1:2020 applies to X-RAY TUBE ASSEMBLIES and to FILTERING MATERIAL, in medical diagnostic applications up to a HIGH VOLTAGE of 150 kV. For HIGH VOLTAGES greater than 50 kV, this document applies to X-RAY TUBE ASSEMBLIES with tungsten or tungsten-alloy TARGETS only.
IEC 60522-1:2021 defines the concept of PERMANENT FILTRATION of X-RAY TUBE ASSEMBLIES, and it defines the term FILTERING MATERIAL.
Methods are given to determine the PERMANENT FILTRATION of an X-RAY TUBE ASSEMBLY and for determining the QUALITY EQUIVALENT FILTRATION of FILTERING MATERIALS.
It contains requirements for statements of compliance of X-RAY TUBE ASSEMBLIES in ACCOMPANYING DOCUMENTS and for markings on X-RAY TUBE ASSEMBLIES, and for indications and statements of compliance of FILTERING MATERIAL.
IEC 60522-1:2020 cancels and replaces the second edition of IEC 60522 published in 1999. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the IEC 60522:1999:
The scope of the IEC 60522-1 has been changed with respect to second edition of the IEC 60522 as follows:
a) As radiotherapy standards do not reference IEC 60522, radiotherapy is no longer in the scope. Consequently, the HIGH VOLTAGE is limited to 150 kV, and copper is no longer used as reference material.
b) While IEC 60522:1999 covers only PERMANENT FILTRATION, IEC 60522-1 also covers quite generally “material filtering the X-RAY BEAM incident on the PATIENT”. This concerns materials like ADDED FILTERS, table-tops, a breast COMPRESSION DEVICE, and materials in the BEAM LIMITING DEVICE. For these materials the defined term FILTERING MATERIAL has been introduced.
c) In order to provide technical and scientific background and rationale on the content of IEC 60522-1, IEC TR 60522-2 was introduced.
