FlXED RESISTORS FOR USE 1N ELECTRONIC
EQUIPMENT
SECTIONAL SPECIFICATION FOR FIXED CHIP RESISTORS
NATIONAL FOREWORD
This Indian Standard, which is identical with IEC Pub I IS-S/QC 400600 ( 1989-03 ) ‘Fixed
resistors for use in electronic equipment, Part 8 : Sectional specification : Fixed Chip Resistor’,
issued by the International Electrotechnical Commission, was adopted by Bureau of Indian
Standards on the recommendation of Resistors Sectional Committee and approval of the Elect-
ronics and Telecommunication Division Council ( LTDC ).
The text of the IEC standard has been approved as suitable for publication as Indian Standard
without deviations. Certain conventions are, however, not indentical to those used in Indian
Standards. Attention is particularly drawn to the following:
a) Wherever the words ‘International Standard’ appear referring to this standrad, they should
be read as ‘Indian Standard’.
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.
In this ,adopted standard, reference appears to certain International Standards for which
Indian Standards also exist. The corresponding Indian Standards which are to be substituted in
their place are listed below along with their degree of equivalence for the editions indicated:

The concerned technical committee has reviewed the provisions of IEC 63 ( 1963 ), IEC 68 and
IEC 410 ( 1973 ), referred in this adopted standard and has decided that they are acceptable for
use in conjunction with this standard.
This standard is intended primarily for use under the IECQ system. A regular Indian Standard
for this component could be different, identical or similar to this standard.
Only the English language text in the International Standard has been retained while adopting it
in this Indian Standard.
