This is kind of conflating two different things.

One thing is conventions around things like where curly braces go, naming conventions for classes and methods and different types of variables, how much whitespace to use where, and so forth. Most of these things don't actually matter at all, but code certainly is easier to read if everyone on a team follows the same ones (so that I know that Foo.bar() is a static method while foo.bar() is a method call on a local variable and _foo.bar() is a method call on an instance variable on the class, without having any other deep knowledge of the code). The point of conventions is basically to get everyone to stop bikeshedding about things that don't matter (like which line a curly brace goes on in an if statement), so that they can shut up and go back to writing code. There's no rational way to decide trivial questions like "how much white space should we use," so rather than having people engaging in pointless holy wars over two versus four spaces, we just establish a convention and stop talking about it. It really does make life easier on a team if people are on the same page there, and there are plenty of tools that make it trivial for people to format their code so it conforms to the conventions.

Then there's the issue of "standards," which is a much larger, amorphous topic that probably shouldn't just be trivialized. Trying to encode them formally is probably madness, but when some person on your team writes a 245-line-long function or calls a method "getFoo" when it in fact writes a file to disk as a side effect, you do probably want to have a little chat during a code review to say, "Hey, yeah . . . so that's not really okay, even if the code functions correctly." That's what I think of as "standards:" the assumption that just getting things to work isn't the only thing that matters. And just throwing that out the window and saying "Anything goes so long as it works" is pretty suicidal if you're working on a team.

The way I addressed your "standards" issue is to just reference the book "Code Complete (2nd edition)" http://www.cc2e.com/ and tell developers to follow all of those guidelines. It's a long book but well worth reading, and generally applicable to most any procedural or OO language.

For Java specifically our "standards" also incorporate the book "Effective Java (2nd edition)" http://www.informit.com/store/effective-java-9780321356680 .
