  ? For the steel types for which sufficient data were available, the proof stress values given were derived from data collected and assessed in accordance with BS 3920, using the smoothed lower 95 % confidence lines. For certain other steel types insufficient data were available and other bases were adopted. ? Values based on 304 smoothed lower 95 % confidence lines.
