In my old age I have become more observant of the ethics involved in such things. I think it all came home to me on the day a friend got quite PO'd when my son suggested he was going to make a copy of the $15 music CD his wife peddles. This was, and you probably know this is coming, the same guy that wanted me to copy Adobe Photoshop for him (or buy him a bootleg copy in Bangkok or something similar). I've got qualms with respect to the ASBC because they are a not for profit organization. Their lifeblood is dues and what they can get for selling publications, check services etc.
The MOA are really just a standardized industry test so that you can take the results and compare them over years and between breweries.
Yes, that is the intent but the industry is the brewing industry. The paint industry does not measure color the way the brewing industry does. The only place where there is 100% cross over is with respect to water chemistry. There are no water chemistry methods in the MOAs. Standard Methods for the Analysis of Water and Waste Water (developed for the drinking water and sewage treatment industries) is incorporated by reference. You can probably find that in libraries. Yes, the test for protein is basically a Kjeldahl test but it has been tweaked for beer/wort. Of course if you are only interested in knowing how to test for protein using Kjeldahl's method you can look it up o Wikipedia.
Now if you are interested in one or 2 I wouldn't have a problem sending those to you (reasoning that the ASBC isn't going to get your money in any case) but I wouldn't feel right about flagrantly violating the license agreement.
Another suggestion you might want to consider: they also publish "Laboratory Methods for Craft Brewers". As the name suggests it is not nearly as extensive (or expensive) as the full set of MOAs and contains all the methods that a home brewer is ever going to contemplate.
I'd also be happy to tell you about what's involved in carrying out any of the analyses that I know about (i.e. the ones I've done).
