IS 3196 : Part 4 : 2001 Welded Low Carbon Steel Cylinders Exceeding 5 Litre Water Capacity for Low Pressure Liquefiable Gases - Specification - Part 4 : Cylinders for Toxic and Corrosive Gases

1 Scope

1.1 This standard deals with welded low carbon steel cylinders intended for storage and transportation of toxic and/or corrosive low pressure liquefiable gases of nominal capacity up to and including 250 litres water capacity. This standard lays down the requirements for the design, materials to be used, manufacture, construction, tests and marking of these cylinders.

1.1.1 Cylinders intended for storage and transportation of methyl bromide gas shall have a maximum nominal capacity up to and including 130 liters water capacity.
