FOREWORD
This Indian Standard ( Part 13/Sec 3) was adopted by the Bureau ofIndian Standards, after the
draft finalized by the Piezoelectric Devices for Frequency Control and Selection Sectional
Committee, LTD 12 had been approved by the Electronics and Telecommunication Division
Council.
This standard shall be read in conjunction with IS 4570( Part 1) : 1983 'Specification for crystal
unit holders: Part I General requirements and tests (firt revision)'.
This standard ( Part 13/Sec 3 ) is based on IEC Doc 49 (C.O.) 223 'Quartz crystal unit outlines
for automatic handling, Types CD 01, CD 02, CD 03, CD 04, CD 05, issued by International
Electrotechnical Commission (lEe ) and covers Quartz crystal unit holder outlines type CD 03.
For the purpose ofdeciding whether a particular requirement ofthis standard is complied with,
the final value, observed or calculated, expressing the result ofa test or analysis, shall be rounded
off in accordance with IS 2 : 1960 'Rules for rounding off numerical values (revised)'. The
number of significant places retained in the rounded oilvalue should be the same as that ofthe
specified value in this standard.
