[MW:6114] IBR certification of Safety/Relief Valve manufacturer in India

Dear Members,

For an IBR audit or certification of a relief valve manufacturer in India, does IBR require the manufacturer to submit spring design data sheets for Boiler Safety Valves? Does IBR also require the same to be submitted for Section VIII valves set on steam?
In any case, does the IBR require spring design data sheets to be provided alongwith the documentation for the relief/safety valves set on steam be the valves for Boiler or Process application?

Regards

Johnson Madukayil
