Actual practice may vary.21.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The va
5、lues stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with
6、 its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

This information is pro-vided for “information only” and should not be considered asrecommendations.X1.1.1 Copper Alloy UNS No. C91300 (Formerly AlloyA)For contact with hardened steel disks at low speeds underpressures not over 3 ksi 20 MPa, for example, disk-bearingmetals used i

43、0 ksi 415 MPa, min) atlow speeds under pressures not over 1.5 ksi 10 MPa, forexample, trunnions of movable bridges; and for bearing andexpansion plates under pressures not to exceed 2.5 ksi.X1.1.3 Copper Alloy UNS No. C90500 (Formerly AlloyD)For gears, worm wheels, nuts, and similar parts that aresu
44、bjected to other than compressive stresses.X1.1.4 Copper Alloy UNS No. C86300 (Formerly AlloyE)For bushings for bridge pins and similar applications inwhich angular movement is slight and compressive stressesmay attain 8 ksi 55 MPa.X1.1.5 Copper Alloy UNS No. C93700 (Formerly AlloyC)For ordinary mac

METRIC EQUIVALENTSX2.1 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 astha
46、t force which, when applied to a body having a mass of 1 kg,gives it an acceleration of 1 m/s2(N = kgm/s2). The derived SIunit for pressure 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
47、, the metric equivalents are expressed as megapascal (MPa),which is the same as MN/m2and N/mm2.SUMMARY OF CHANGESCommittee B05 has identified the location of selected changes to this standard since the last issue (B22 09)that may impact the use of this standard.
