A note (or other information) needs to be added to E517 that the r-value of magnesium alloys and high strength aluminum alloys are sensitive to the gage length used for its determination. This Work Item will add a statement or brief discussion to this effect to E517. Some discussion as to what to do about this may also be presented.
