Testing infant car seats

Even though parents around the world are all so different, they have one thing in common. They all share the same concern for the safety of their children. Particularly in the car, this is a topic where compromise simply is not an option. To help parents choose the right car seat or infant carrier for their children, standards have been implemented across the world. The current mandatory standard is ECE R44/04. Since 2013, the ECE 129 regulation runs in parallel and states that a rearward-facing car seat is mandatory for children up to 15 months. In addition to the legal requirements, infant carriers and car seats are also checked and tested by independent testing institutes such as German automobile club (ADAC) and Stiftung Warentest. To emerge as the winner of such a test, products must meet stringent requirements in a variety of different categories.

Example ADAC: How are baby car seats tested?

The child seat tests are carried out by a consortium of different mobility clubs and consumer organisations (ADAC, ÖAMTC, TCS, Stiftung Warentest) once or twice a year. The mobility clubs and consumer protection organizations publish the test results. The German automobile club ADAC tests car seats and infant carriers from each group in front and side-impact collisions. The front impact collision takes place at a speed of 64 km/h whereas the side-impact collision impacts at a speed of 50 km/h. Depending on the weight category, dummies of varying sizes are used in various crash situations to simulate the effects of an accident on children of differing ages and weights as accurately as possible. In addition to the crash test, further tests are carried out to evaluate the safety of the child seats with regards to misuse potential, handling, ergonomic design, cleaning properties, workmanship and the presence of harmful substances. The car seats are also tested in everyday use with real children and parents.

Why is a baby car seat test so important?

The test criteria of e.g. the ADAC test are far stricter than the requirements of the ECE-R 44 standard and are constantly being tightened. Accordingly, the acceptable critical values and categories are under constant review. 2011, for example, saw the implementation of tests for harmful substances in car seats. Therefore, tests of this kind make a significant contribution to enhancing the safety of car seats and infant carriers over time.
