Bronze valves ....Radiography???

Hi everybody,
I would like to know if it is necessary to radiograph bronze valve casting. Does anybody know if their are vendors who give Bronze valves with radiography. Also are their any standards which specify the percentage of radiography. If radiography is not done what other test is used to certify the valve body.

Also one of our vendors gives bronze ball valve with Fire safe Design but does not give the Fire safe certificate. What does fire safe design imply without a fire safe test certificate ?? Can bronze valve undergo a fire safe test??

The bronze valve is used in firewater service.
