No, 1.4 is not an universal standard. With the CMAS in Europe, the limit is 1.6 and you can dive up to 40 meters with 32%. I find 1.4 too much low.Rainer:Furthermore, 1.4 isn't a universal standard. Many tech divers will go above it for deco. The U.S. Navy is also more conservative, and uses 1.3. GUE teaches 1.2 (for cold diving).
