IEC 60522-1-2020 pdf free.Medical electrical equipment – Diagnostic X-rays – Part 1: Determination of quality equivalent filtration and permanent filtration.
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.
NOTE 3 This document does not contain requirements for any specific values of PERMANENT FILTRATPON, For X-RAY
EQUIPMENT used for diagnostic purposes, FILTRATION requirements are given in e.g. IEC 60601-1-3:2008 and
IEC 60601-1-3:2008IAMD1:2013 or in the applicable particular standard.
NOTE 4 The method of determination described in this document is suitable as a type test. It is not intended as a test to be applied by the USER.

3.1 FILTERING MATERIAL
material between the X-RAY TUBE ASSEMBLY and the PATIENT which causes FILTRATION of the
X-RAY BEAM
3.2 PERMANENT FILTRATION
QUALITY EQUIVALENT FILTRATION effected in an X-RAY TUBE ASSEMBLY by permanently fixed materials intercepting the X-RAY BEAM, that are not intended to be removed for any application and are not provided with means for removal in NORMAL USE
3.3 QUALITY EQUIVALENT FILTRATION
quantitative indication of the FILTRATION effected by one or several layer(s) of reference material(s) which, if substituted in a beam of specified RADIATION QUALITY under NARROW BEAM CONDITION for the material under consideration, give(s) the same RADIATION QUALITY as for the material under consideration
Note 1 to entry: The QUAlITY EQUIVALENT FILTRATION Is expressed In suitable subrnultiples of the metre together
with the reference material(s).
Note 2 to entry: In this document. RADIATION QUALITY Is characterized by Its first HALF-VALUE LAYER.

4 Determination of QUALITY EQUIVALENT FILTRATION
4.1 Alignment of X-RAY TUBE ASSEMBLIES and of the FILTERS
If, apart from the X-RAY TUBE ASSEMBLY under test, a reference X-RAY TUBE ASSEMBLY is used. then their REFERENCE AXES shall be aligned.IEC 60522-1 pdf free download.
