National Small Series Type Approval (NSSTA)

Small Series

If you manufacture modest numbers of vehicles then this route to approval may be right for you.  Again, this option is based on the concept of "type" approval rather than the approval of individual vehicles.  The key advantages of this scheme are that some technical requirements may be reduced, which will have an impact on the costs associated with the approval process and the Conformity of Production (CoP) requirements will be appropriate and proportionate to the scale of your operation.  However, the key disadvantages revolve around the fact that you will be limited to the number of vehicles you can manufacture in the year and there is a limited requirement for other Member States to accept National approvals.

As with ECWVTA the manufacturer will be responsible for the issue of Certificates of Conformity within the limited numbers set out in the relevant legislation.

What is a Type?

On the face of it, you may feel that you have many vehicles to approve but in practice, these may boil down to just a few "types".  But how is a type defined?

Essentially, a type can best be viewed as a range of vehicles, which share a set of fundamental characteristics (these are described in the Directive at Section B of Annex II)

In multi-stage type approval, where the vehicle is built in more than one stage, such as a manufacturer building a chassis cab and a body builder/converter adding a tipper body, each manufacturer's chassis type will require a type for the following stage.
