What do you mean by "more info?" The standard itself is quite good at explaining the process by which to design a storage tank. Are you looking for history on the standard itself or guidance on how to use it for your project?
Yes the history of the standard is useful. Alot of my tanks were built in the 1970's and I need to see old and new editions to the 650 standard. Any good websites that can help me out on that?
