Description / Abstract:

This International Standard applies to X-RAY TUBE ASSEMBLIES for medical diagnosis and RADIOTHERAPY.


This standard 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.

NOTE 1 This standard does not contain requirements for any specific values of PERMANENT FILTRATION or TOTAL FILTRATION to be provided. For X-RAY TUBE ASSEMBLIES and X-RAY EQUIPMENT used for diagnostic purposes, appropriate requirements are given in IEC 60601-1-3.

NOTE 2 The method of determination described in this standard is suitable as a type test. It is not intended as a test to be applied by the USER.
