http://standards.ieee.org/catalog/olis/dtransformers.html
has a list of transformer-related standards from IEEE.
62-1995 IEEE Guide for Diagnostic Field Testing of Electric Power Apparatus--Part 1: Oil Filled Power Transformers, Regulators, and Reactors - has a few specs for moisture etc.
There's also a few guides in that link for reclamation of tranformer oil, specs for silicon oil (fire retardant). I remember one more specifically on limits for transformer oil (prior to putting it in transformers), but I didnt see it at the above link.
Midel provides their oil up to 50ppm moisture? Way too high for high-voltage transformers.
RE: transformer oil
There is also an ASTM Standard D-117 "Standard Method of Testing and Specifications for Electrical Insulating Oils of Petroleum origin"
Transformer oil is also commonly refered to as 10C oil.
