I've been professionally involved with standards production in both the US and 
Europe over about the last 15 years, and would only say Jim is partially 
correct. There is frequently a high degree of commercial interest in the 
production of a standard such that it helps one party commercially, and 
possibly disadvantages another - a good example was the long drawn out wrangle 
over the 3G mobile telephony standard. Similarly, another on running case is 
the present wrangle over a UWB standard in IEEE 802. One difficulty that also 
emerges is when a standards committee expert in one field attempts to stray to 
other fields, and classic examples here exist in CENELEC, the European 
electrical standards committee. It happens every so often when they attempt to 
stray into or near the radio field, for example, with standards for radio 
station installation or EMC matters concerning radio telemetry in the medical 
field.
