Where does this come from? The US piping codes specify one allowable only (I was just joking about liberal and conservative and faith-based allowables). You can apply factors to that one allowable in specific named circumstances to evaluate secondary stress and certain thermal stresses. Are you referring to the allowable primary plus secondary stress as being governed by a 'liberal' allowable?
