A bstract A method is given to determine the sag‐resisting properties and the effect of the composition of enameling iron, its gauge, and the temperature on sag values. A theoretical consideration of the deflection of beams is also given. Two types of test strips, one 12 inches long supported near the ends and the other 5.55 inches long and supported at one end, were used. Both types have merit, but the 12‐inch strip seemed to give better results. The composition of the iron seemed to affect the sag values, e.g. , mild steel, with more carbon and manganese, showed higher sag values than enameling iron. The heavier gauge values decreased the amount of sag. Sag values increased with increase of temperature, particularly above 1500°F.
