MT 32 - TC 62/SC 62B/MT 32

IEC 60806:2022 is applicable to X-RAY SOURCE ASSEMBLIES and X-RAY TUBE ASSEMBLIES.
This document specifies a method for the determination of the greatest geometrically symmetrical RADIATION FIELD at a specified distance from the FOCAL SPOT for which the percentage AIR KERMA RATE along the major axes of the RADIATION FIELD does not fall below a permitted value.
In case multiple FOCAL SPOTS are not super-imposed, each FOCAL SPOT has its own REFERENCE AXIS. Then the maximum RADIATION FIELD can be given for each FOCAL SPOT separately.
IEC 60806:2022 cancels and replaces the first edition published in 1984. This edition constitutes a technical revision.
This edition includes the following significant technical change with respect to the previous edition:
a) addition of solid state detectors as they have become more common since the first edition of 1984.

IEC 60336:2020 applies to FOCAL SPOTS in medical diagnostic X-RAY TUBE ASSEMBLIES for medical use, operating at X-RAY TUBE VOLTAGES up to and including 150 kV.
This document describes the test methods employing digital detectors for determining:
a) FOCAL SPOT dimensions in terms of NOMINAL FOCAL SPOT VALUES, ranging from 0,1 to 3,0;
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.
The contents of the corrigendum of June 2022 have been included in this copy.

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.

IEC 60601-2-28:2017 is also available as IEC 60601-2-28:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 60601-2-28:2017 applies to the basic safety and essential performance of X-ray tube assemblies and to components thereof, intended for medical diagnosis and imaging. Where the general standard IEC 60601-1 and the collateral standard IEC 60601-1-3 refer to me equipment, this is interpreted as X-ray tube assemblies in this particular standard. If a clause or subclause is specifically intended to be applicable to ME equipment only, or to ME systems only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to ME equipment and to ME systems, as relevant. The third edition of this particular standard has been prepared to fit IEC 60601-1:2005 and IEC 60601-1:2005/AMD1:2012 (the amended third edition of IEC 60601-1), which is referred to as the general standard. Apart from the changes related to the amendment of IEC 60601-1, changes related to technical improvements are also included.

IEC 60601-2-28:2010 establishes particular basic safety and essential performance requirements for X-ray tube assemblies for medical diagnosis. This second edition cancels and replaces the first edition published in 1993. This edition constitutes a technical revision. The second edition of this particular standard has been prepared to fit IEC 60601-1:2005 (the third edition of IEC 60601-1), which is referred to as the general standard.

IEC 60613:2010 applies to X-ray tube assemblies either with a rotating anode X-ray tube or a stationary anode X-ray tube, intended for use in medical diagnosis. For an X-ray tube head, its X-ray tube assembly aspects are also within the scope. IEC 60613:2010 covers performance-related definitions and conditions of electrical and loading characteristics of X-ray tube assemblies in relation to their behaviour during and after energization and, where appropriate, methods of presentation and measurement of these characteristics. This International Standard is therefore relevant for the manufacturer and the responsible organization. This third edition cancels and replaces the second edition of IEC 60613, published in 1989. It constitutes a technical revision. This third edition has been adapted to apply to the present technology.

Applies to focal spots in medical diagnostic X-ray tube assemblies or medical use, operating at X-ray tube voltages up to and including 200 kV. Describes the test methods for evaluating focal spot characteristics and the means for indicating compliance. The contents of the corrigendum of May 2006 have been included in this copy.

Defines the concept of permanent filtration in X-ray tube assemblies for medical diagnosis and radiotherapy and describes a method for its determination. It contains requirements for statements of compliance for accompanying documents and for markings on X-ray tube assemblies. Methods are given to determine the permanent filtration in an X-ray tube assembly with an accuracy that is sufficient to enable the appropriate additional filtration to be provided in order to attain the desired total filtration.
