IS/ISO 9809 : Part 2 : 2019 Gas Cylinders - Design, Construction and Testing of Refillable Seamless Steel Gas Cylinders and Tubes - Part 2 Quenched and Tempered Steel Cylinders and Tubes with Tensile Strength Greater than or equal to 1 100 MPA

NATIONAL FOREWORD

This Indian Standard (Part 2) which is identical to ISO 9809-2 : 2019 'Gas cylinders - Design, construction and testing of refillable seamless steel gas cylinders and tubes - Part 2: Quenched and tempered steel cylinders and tubes with tensile strength greater than or equal to 1 100 MPA' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Gas Cylinders Sectional Committee and approval of the Mechanical Engineering Division Council.

The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical to those used in Indian Standard. 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.
