Disclosure to Promote the Right To Information

Whereas the Parliament of India has set out to provide a practical regime of right to
information for citizens to secure access to information under the control of public authorities,
in order to promote transparency and accountability in the working of every public authority,
and whereas the attached publication of the Bureau of Indian Standards is of particular interest
to the public, particularly disadvantaged communities and those engaged in the pursuit of
education and knowledge, the attached public safety standard is made available to promote the
timely dissemination of this information in an accurate manner to the public.

NATIONAL FOREWORD

This Indian Standard ( Part 2 ) which is identical with IS0 2162-2 : 1993 ‘Technical product docu-
mentation - Springs - Part 2 : Presentation of data for cylindrical helical compression springs’
issued by the International Organization for Standardization ( IS0 ) was adopted by the Bureau of
Indian Standards on the recommendation of Drawings Sectional Committee and approval of Light
Mechanical Engineering Division Council.
This standard was originally published in 1983 by adopting IS0 2162 : 1973 ‘Technical drawings -
Representation of springs’. IS0 2162 has since been revised in 1993 by splitting it into the
following three parts, under the general title ‘Technical product documentation - Springs’.

Part 1 Simplified representation

Part 2 Presentation of data for cylindrical helical compression springs

Part 3 Vocabulary
In view of the above, the committee responsible for the formulation of this standard has also
decided to revise IS 10716 : 1983 splitting into three parts by adopting the above three parts of IS0
2162 respectively.
This standard ( Part 2 ) establishes a uniform system for the presentation of data and for the
representation of cylindrical helical compression springs to be used in technical product
documentation. Other parts of this series are given as follows:
IS 10716 ( Part 1 ) : 1999 Technical product documentation - Springs : Part 1 Slmpllfled
representation ( first revision )
IS 10716 ( Part 3 ) : 1999 Technical product documentation - Springs : Part 3 Vocabulary

The text of IS0 has been approved as suitable for publication as Indian Standard without
deviations. Certain conventions are, however, not identical to those used in Indian Standards.
Attention is especially drawn to the following:

Wherever the words, ‘International Standard’ appear, referring to this standard, they should be
read as ‘Indian Standard’.
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:

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
