METRIC EQUIVALENTSX1.1 The SI unit for strength properties now shown is inaccordance with the International System of Units (SI). Thederived SI unit for force is the newton (N), which is defined asthat force which when app
48、lied to a body having a mass of onekilogram gives it an acceleration of one metre per secondsquared (N = kgm/s2). The derived SI unit for pressure orstress is the newton per square metre (N/m2), which has beennamed the pascal (Pa) by the General Conference on Weightsand Measures. Since 1 ksi = 6 894
49、 757 Pa, the metric equiva-lents are expressed as megapascal (MPa), which is the same asMN/m2and N/mm2.SUMMARY OF CHANGESCommittee B05 has identified the location of selected changes to this standard since the last issue (B 534 01)that may impact the use of this standard.(1) A comprehensive five-year review was conducted. Notechnical changes were made to temper and property require-ments. Some sections were rearranged, renumbered, and insome cases reworded to conform to the new Outline of
