I checked my bookshelf and found in McFerrin's The Piano - Its Acoustics the following (p 152): "The pitch that has become standard is 440 Hz at 68 degrees Farenheit for A-49. This standard was chosen as the official pitch to be recommended by the American Federation of Musicians in 1917. It was adopted by the US government in 1920, by the Associated Music Industries in 1925, and by the International Conference on Pitch in London in 1939." Doesn't say anything about that conference - who attended, what countries were represented, etc. But I guess maybe 440 is law in the USA, if this quote is to be believed. Nothing mentioned about a treaty. I'd guess the PTG written test is a wee bit inaccurate in its answer to that question. Somebody interpreted "conference" as "treaty."
