FOREWORD
This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the Sewing
Machines Sectional Committee had been approved by the Mechanical Engineering Division Council.
This standard is prepared and published with the interest to facilitate standardization of the sewing machine Head
to be used in manufacturing of the sewing machines and longstanding requirement of the standard on sewing
machine Head will be met. The reference to the latest sewing machine components and performance requirement
standards has been made in this standard.
In preparing this standard, assistance has been derived from the following:
JIS B 9011 : 1978 Household lock stitch machine, issued by Japanese Industrial Standards Committee
JIS B 9014 : 1975 Household straight lock stitch sewing machine heads, issued by Japanese Industrial
Standards Committee
For the purpose of deciding whether a particular requirement of this standard is complied with, the final value,
observed or calculated, expressing the result of a 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 off value should be the same as that of the specified value in this standard.
