The Scope of the Truck and Bus Coupling and Interchangeability Committee is to establish minimum performance requirements and standard test procedures for fifth wheels. Any model of fifth wheel tested to this standard should properly couple and uncouple to a commercial SAE J700 (2 inch) kingpin. The performance requirements are to be based on actual fifth wheel loadings, sound engineering judgment and wherever possible, in harmony with existing standards and/or practices.
