Specifies requirements for 50 mm and 90 mm kingpins for semitrailers used in articulated vehicles, B-doubles, and road trains, in normal use on both sealed and unsealed roads.

This Standard specifies requirements for 50 mm and 90 mm kingpins for semitrailers used in articulated vehicles, B-doubles, and road trains, in normal use on both sealed and unsealed roads.The requirements cover mechanical properties, dimensional standards for interchangeability, dynamic testing (see Appendix A) and calculation of D-ratings (see Appendix B).NOTES:1 Recommendations and requirements for fifth wheel assemblies on prime movers are given in AS 1771 and AS 1773.2 Recommended wear limits are given in Appendix C.3 Guidance on the attachment of kingpins is given in Appendix D.
