New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard which is identical with ISO 17939 : 2015 ‘Ships and marine technology - Oil tank hatches’ issued by International Organization for Standardization (ISO), was adopted by the Bureau of Indian Standards, on recommendation of the Shipbuilding Sectional Committee and approval of the Transport Engineering Division Council.

The text of ISO Standard has been proposed to be approved as suitable for publication as an Indian Standard without deviations. Certain conventions and terminologies 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.
