IS 18443 : 2025 Medical Electrical Equipment - X-Ray Tube Assemblies for Medical Diagnosis - Focal Spot Dimensions and Related Characteristics (IEC 60336 : 2020, MOD)
(Superseding IS/IEC 60336 : 2005)
NATIONAL FOREWORD
This Indian Standard which is modified adoption of IEC 60336 : 2020 + COR 1 'Medical electrical equipment - X-ray tube assemblies for medical diagnosis - Focal spot dimensions and related characteristics' issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendation of the Electromedical, Diagnostic Imaging and Radiotherapy Equipment Sectional Committee and approval of the Medical Equipment and Hospital Planning Division Council.
This standard was first published in 1986 as IS 12024 which was based on IEC Pub 336 (1982) 'Characteristics of focal spots in diagnostic X-ray tube assemblies for medical use'. It was superseded by IS/IEC 60336 : 2005 which was an identical adoption of IEC 60336 : 2005 'Medical electrical equipment - X-ray tube assemblies for medical diagnosis - Characteristics of focal spots'. This publication supersedes IS/IEC 60336 : 2005.
Corrigendum 1 issued in 2022 to IEC 60336 : 2020 has been incorporated at the end of this publication. The text of IEC standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards.
Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'; and
b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
