Bases of Material Selection

The bases of material selection is that they must all have an easy to dissociate hydroxyl radical.

The basis of any material selection in any environment is to first clearly identify all of the anticipated conditions of that environment and the likely forces applied onto that material. Low temperature service in a refrigerator in Miami FL. will be different from any mountaineering equipment and even further different for a Martian rover.

Indeed a good answer. I would add that there are a number of bases that do not necessarily have 'an easy to dissociate hydroxyl radical'....and I'm not just referring to those commonly associated with different types of strikes (military or umpires)...

.

Methylamine, CH₃NH₂, is a good example. So is ammonia, NH₃. Both are definitely bases, yet lack any easily cleaved/donated hydroxyl radical.

.

Sometimes a useful definition off bases involves the ready acceptance of hydron cations (or the more involved exchange for which it is the net result).....though that still leaves out 'military bases' and 'who is on 1st'.

The ability to withstand low temperatures.

What else!

Hopefully there is more information forthcoming from OP. I have the feeling we can get this thread very very far!

Er, how about the experimental activities and practical experience that went into creating the facility's Piping Standards Manual?
