Whole vehicle type approval

All three outward forms are basically demanding EC approved components. The difference in demand is how documents are verified.

According National Type approval
National whole vehicle type approval offers possibilities to in small series manufacturing of vehicle families in specified variants. This approval can be given with reduced outward forms.
Those type approved can only be  without any additional inspection within approved country. The vehicles can NOT freely be sold in any other country member of EC.
Components and system where EC approval are requested such as coupling equipment and underrun protection has to be mounted according to registrered mounting instruction and be verified according to relevant EC directive demand.

Single approval
Single approval registration is NOT intend for serial manufacturing of vehicle families but there is no restrictions in numbers. Vehicles single approved can not be freely sold in other countries member of EC without new inspection, but with high level of the documentation the adminstration will be easier handled.
Every indiviual vehicle or trailer has to be inspected before approval. The adminstration will be simplified for each every product that are approved according relevant EC directive. The handling of single approval are similar to present inspection.
