45、t 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 applied to a body having a mass of 1 kggives it an acceleration of 1 m/s2(N = kgm s2). The derived SIunit for pres
46、sure or stress is the newton per square metre(N/m2), which has been named the pascal (Pa) by the GeneralConference on Weights and Measures. Since 1 ksi = 6 894 757Pa, the metric equivalents are expressed as megapascal (MPa),which is the same as MN/m2and N/mm2.SUMMARY OF CHANGESCommittee B05 has iden
47、tified the location of selected changes to this standard since the last issue(B570 06(2010) that may impact the use of this standard. (Approved Oct. 1, 2016.)(1) There were no technical changes.
