Clarity in writing and drawings should never be sacrificed by using abbreviations. This could lead to a misunderstanding in the meaning. You shouldalways avoid abbreviations in technical writing and on drawings that are going to be distributed to foreign countries.

This list by no means is complete and variations may be found.
