Specifies performance requirements and recommendations for the installation of fifth wheel assemblies. Applies to fifth wheel assemblies used with 50mm, 75mm and 90mm kingpins for articulated vehicle combinations used in heavy road vehicles, B-doubles and road trains, in normal use on both sealed and unsealed roads.

This Standard sets out performance requirements and recommendations for the installation of fifth wheel assemblies. Alternative designs and methods of assembly which do not comply with a specific requirement of this Standard or are not mentioned in it, but which give at least equivalent results are not prohibited. This Standard applies to fifth wheel assemblies used with 50 mm, 75 mm and 90 mm kingpins (referred to in AS/NZS 4968.3) for articulated vehicle combinations used in heavy road vehicles, B-doubles and road trains, in normal use on both sealed and unsealed roads. The requirements cover dimensional standards for interchangeability, strength testing and rating. NOTES: 1 Additional components not specified or supplied by the fifth wheel manufacturer for a typical installation but necessary for a specific installation (e.g. attachment brackets) are not covered by this Standard. 2 Methods for determining D-value for fifth wheel assemblies are specified in AS/NZS 4968.1. 3 Criteria for 50 mm, 75 mm and 90 mm kingpins are specified in AS/NZS 4968.3. 4 Design criteria for trailer skid plates are specified in AS/NZS 4968.3.
