NATIONAL FOREWORD
This Indian Standard (First Revision) which is identical with ISO 6067:1985 ‘Shipbuilding and marine
structures — Winches for lifeboats’ issued by the International Organization for Standardization (ISO)
was adopted by the Bureau of Indian Standards on the recommendations of the Marine Engineering
and Safety Aids Sectional Committee and approval of the Transport Engineering Division Council.
The Indian Standard was first issued in 1979. This revision has been taken to harmonize it with latest
version of ISO Standard.
The text of the International 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 while in Indian Standards, the current practice
is to use a point (.) as the decimal marker.
