A quality wrench should come with a recommended cal schedule. Unfortunately it also depends on use and other factors. For home shop use or for that matter any shop use ALL new tools need 100% calibration by an independant shop. I have worked in a big time cal lab at Xerox when I was a student engineer. We calibrated 100% of everything new. We found an astounding number of things way out of spec. From $10 tools to $100,000 tools, no exceptions. After that, for home use, on a torque wrench, get two and cross check every once in a while, eg ck your 50 ft lb wrench at 50 against your 150 ft lb wrench. If ok use it. (This is a TOTAL NO NO for any commercial use and not a recognized cal technique, but for home use, what the heck)
