Child restraint systems –Accredited crash testing

VTI's crash safety laboratory has long and solid experience of testing child restraint systems and was among the first in the world to start performing such.

Important information to our clients about Plus Test

As mentioned in the text below VTI is making major investments to be able to offer testing according to R129. Some of the key elements are however still missing and is delaying the new testing. In addition the calibration of our P-dummies is no longer valid.

It is with great regret that we have to inform our clients that we do not approve any child restraint systems (CRS) according to the Plus Test until earliest by the end March 2023. We will still offer non-approval crash tests to get a preview if the CRS will pass the Plus Test.

VTI's involvement in the design of testing and its methods started in the 1960s. Since then, VTI has actively participated in the development of testing and crash safety for children in vehicles.

In 2021 and 2022, VTI will make a major investment in the forms of a new brake system, new test rig, and new crash dummies to be able to offer testing by ECE Regulation 129. The standard ECE Regulation 44, which VTI previously performed testing according to, has existed since 1974. To meet today's development regarding road safety, ECE Regulation 129 was created. This means that the ECE Regulation 44 is being phased out.

New for ECE Regulation 129 is, among other things, that the length of the child determines which child restraint system (CRS) should be used in harmony with the recommended maximum weight. In the test, a side impact test and several advanced measurements in the crash dummy have been added.

In connection with the update and entry into ECE Regulation 129, in the autumn of 2022, VTI's Plus Test will also undergo a renewal. All to give the child extra safety in traffic.

Testing and E-approval

E-approval is European, and such mandatory testing and approval are governed by ECE Regulation 44 and ECE Regulation 129. ECE stands for Economic Commission for Europe. In Sweden, the Swedish Transport Agency issues the E-approval after testing at VTI. The approval will be valid in all countries that have accepted the regulations. E-approval is mandatory for all child restraint systems.

Plus Test

Plus Test is a voluntary supplementary test to the E-approval and is ordered by the CRS manufacturers, who want to demonstrate qualities in addition to those included in mandatory ECE Regulation 44 or ECE Regulation 129. In a Plus Test, the speed increases to 56 km/h, and the stopping distance is reduced by about 100 mm. We also measure the forces that the child's neck exposes to in a frontal collision. A child restraint system that has passed the Plus Test gives the child a little extra safety and reduces the risk that the child traveling in it exposes to life-threatening high neck forces in a frontal collision.

The Plus Test has been developed in a collaboration between VTI, NTF (National Society for Road Safety), Folksam, SIS (Swedish Standards Institute), Volvo, and representatives of CRS manufacturers.

Prototype testing

VTI's crash safety laboratory also conducts prototype testing of child restraint systems. The testing has many elements, including dynamic testing and component testing.
