1、Designation: B22/B22M 15Standard Specification forBronze Castings for Bridges and Turntables1This standard is issued under the fixed designation B22/B22M; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A

2、 number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1 This specification establishes requirements for

3、 bronzecastings for turntables, movable bridges and bridge parts, andbronze castings suitable for use in bridges and other structuresfor fixed and expansion bearings in which motion is slow andintermittent. The following Copper Alloys are specified: UNSNo. C86300, C90500, C91100, C91300, and C93700.

4、NOTE 1Historically, the alloys in this specification have been used inthe applications listed in Appendix X1. Actual practice may vary.21.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. Within the text, SIunits are shown in brackets. The values st

5、ated in each systemmay not be exact equivalents; therefore, each system shall beused independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.1.3 The following safety hazard caveat pertains only to thetest method(s) described in this specificat

6、ion:1.3.1 This standard does not purport to address all of thesafety concerns, if any, associated with 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. Refere

45、sures not over 2.5 ksi 17 MPa, for example, disk-bearingmetals used in turntable and center-bearing swing bridges; forcontact with steel (tensile strength 60 ksi 415 MPa, min) atlow speeds under pressures not over 1.5 ksi 10 MPa, forexample, trunnions of movable bridges; and for bearing andexpansion

46、 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 aresubjected to other than compressive stresses.X1.1.4 Copper Alloy UNS No. C86300 (Formerly AlloyE)For bushings for bridge pins and similar applicat

47、ions 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 machinery bearings and for bearing andexpansion plates under pressures not to exceed 1 ksi 6.9 MPa.X2. METRIC EQUIVALENTSX2.1 The SI unit for stren

48、gth 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 kg,gives it an acceleration of 1 m/s2(N = kgm s2). The derivedSI unit for pressure or s

49、tress 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 identified the location of selected changes to this standard since the last issue(B22/B22M 14) that may impact the use of this standard.
