NATIONAL FOREWORD

This Indian Standard (Third Revision) which is identical to ISO 4633 : 2023 'Rubber seals - Joint rings for water supply, drainage and sewerage pipelines - Specification for materials' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Rubber and Rubber Products Sectional Committee and approval of the Petroleum, Coal and Related Products Division Council.

This standard was first published in 1969 and subsequently revised in 1985 and 2018.

This revision has been brought out to align with the latest version of ISO 4633 : 2023 in dual numbering system to make pace with latest developments that have taken place at international level.

The text of ISO standard has been 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'; and

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.
