All car seats available in the EU must pass the ECE standard testing. This, however, is limited to individual car seat parts and fails to measure the force the neck and head are subjected to in a car accident. A car seat may pass the test without ascertaining how the child's neck or head would be affected in case of a car accident.
In Sweden, the forces to which the child's body is subjected are also measured. These tests clearly show that children seated in rear-facing car seats are 5 times safer than children in forward-facing car seats.
