Bibliography

The scope of this part is: - to describe the design process of switches and crossings, and the use of the other parts of this standard; - to define the main criteria to be taken into account during the design of the layout, including the safety and functional dimensions as well as geometrical and material aspects; - to define the main criteria to be verified during the design approval; - to define the geometrical and non-geometrical acceptance criteria for inspection of layouts assembled both in the fabrication plant and at track site in case of layouts that are delivered non or partially assembled or in a "kit" form; - to determine the limits of supply; - to define the minimum requirements for traceability.
