Project: Development of Harmonised Side Impact Test Procedures

Reference: S0220/VF

Last update: 08/01/2009 09:48:46


The main objectives of this project are to improve and harmonise side impact testing through the development and delivery of the following:

* an advanced full-scale barrier based side impact test procedure;
* an interior surface test procedure; and
* supporting Regulatory Impact Assessments.


The Department for Transport wishes further to improve occupant protection in car to car side impacts, the second most common accident configuration after frontal impact, using test procedures based on sound scientific research. Research of this nature is normally carried out collaboratively by members of the European Enhanced Vehicle Safety Committee (EEVC) and more recently by members of the International Harmonisation of Research Activities (IHRA). Previously, work undertaken for member states by the EEVC has produced the test methods used in European legislation and by Euro NCAP.

Other countries, namely the USA, have carried out similar research and developed their own test procedures for adoption in their national legislation. Although these different standards have the same aim they are tailored for their respective markets and so vehicles designed to meet one standard might not satisfy the other. However, it should be possible to harmonise certain aspects and for compliance with the more onerous standard to be accepted in lieu of compliance with the other. In this way global harmonisation could be achieved to the benefit of industry without compromise at the regional level.

Given the body of research and the delivery route, improvements to the test procedures should take into account relevant research and be carried out in collaboration with the EEVC and IHRA, the former having set out recommendations for future side impact testing. As milestones are set to coincide with the Enhanced Safety Vehicle (ESV) conferences, the work should be carried out in two phases and reported prior to the conferences scheduled for 2003 and 2005. The first phase will culminate in the delivery of viable draft test procedures that will be validated during the second phase. The work should be scheduled to allow for the production version of the global side impact dummy "WorldSID" that should be available by Spring 2004.

Summary of results

  1. This research programme was undertaken to continue the support provided by the UK in the development of global
    harmonised side impact test procedures. In particular, the programme investigated the development of a full scale side impact mobile deformable barrier test procedure and a sub-system interior surface test procedure.
