NATIONAL FOREWORD
This Indian Standard which is identical with ISO 16163:2005 ‘Continuously hot-dipped coated steel
sheet products — Dimensional and shape tolerances’ issued by the International Organization for
Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the
Wrought Steel Products Sectional Committee and approval of the Metallurgical Engineering Division
Council.
This Indian Standard has been taken up to align it with ISO 16163:2005 by adoption under dual
numbering system.
The text of ISO Standard has been approved as suitable for publication as an Indian Standard without
deviations. Certain conventions are, however, not identical to those used in Indian Standards.
Attention is particularly drawn to the following:
a) Wherever the words ‘International Standard’ appear referring to this standard, they should
be read as ‘Indian Standard’.
b) Comma (,) has been used as a decimal marker in the International Standards, while in
Indian Standards, the current practice is to use a point (.) as the decimal marker.
In reporting the results of a test or analysis made in accordance with this standard, if the final value,
observed or calculated, is to be rounded off, it shall be done in accordance with IS 2: 1960 ‘Rules for
rounding off numerical values (revised)’.
