IS/IEC 61262 : PART 2 : 1994 : Medical Electrical Equipmnent Characteristics of Eectro-Optical X-ray Image Intensifiers : Part 2 Determination of the Conversion Factor

NATIONAL FOREWORD

This Indian Standard (Part 2) which is identical with IEC 61262-2 : 1994 Medical electrical equipment - Characteristics of electro-optical X-ray image intensifiers - Part 2: Determination of the conversion factor' issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendation of Ionizing Radiation Imaging and Radiotherapy Equipment Sectional Committee and approval of the Medical Equipment and Hospital Planning Division Council.

This standard was first published in 1993 as IS 13813 : 1993 by adopting IEC Pub 573 : 1-977. IEC Pub 573 :1977 had been withdrawn and replaced by IEC 61262-2 :1994.This standard will therefore, supersedes IS 13813:1993'Measurement of the conversion factor of electro-optical X-ray image intensifiers' and after the publication of this standard IS 13813 :1993 shall be treated as withdrawn.

IEC 61262 has been published in various parts. The other parts which have been adopted so far are:

Part 1 Determination of the entrance field size

Part 3 Determination of the luminance distribution and luminance non-uniformity

Part 4 Determination of image distortion {underpreparation)

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'.

b) Comma (,) has been used as a decimal marker in the International Standard while in Indian Standards, the current practice is to use a point (.) as the decimal marker.>
