NATIONAL FOREWORD
This Indian Standard which is identical with ISO 9904:2000 ‘Textile machinery and accessories— Steelpins for spinning preparatory and spinning machinery’ issued by the International Organization forStandardization (ISO) was adopted by the Bureau of Indian Standards on the recommendations of theSpinning Preparatory, Spinning and Doubling (Twisting) Machinery Sectional Committee (TX 15) andapproval of the Textile Division Council.
The text of ISO Standard has been proposed to be approved as suitable for publication as an IndianStandard without deviations. Certain cor,ventions are, however, not identical to those used in IndianStandards. Attention is particularly drawn to the following:
a) Wherever the words ‘International Standard’ appear referring to this standard, they shouldbe read as ‘Indian Standard’.
b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practiceis to use a point (.) as the decimal marker.
In the Bibliography of the standard being adopted reference appears to certain International Standardsfor which Indian Standards also exist, as listed below:

Bureau of Indian Standards
BIS is a statutory institution established under the Bureau of /ndian Standards Act, 1986 to promote
harmonious development of the activities of standardization, marking and quality certification of
goods and attending to connected matters in the country.

Review of Indian Standards
Amendments are issued to standards as the need arises on the basis of comments. Standards are also
reviewed periodically; a standard along with amendments is reaffirmed when such review indicates that
no changes are needed; if the review indicates that changes are needed, it is taken up for revision.
Users of Indian Standards should ascertain that they are in possession of the latest amendments or
edition by referring to the latest issue of ‘BIS Catalogue’ and ‘Standards: Monthly Additions’.
