Head form impact tests are carried out on instrument panel as part of meeting the requirements of the interior fitting regulation ECE R India adopted the ECE R21 regulation and interior fitting impact tests became mandatory in April for models manufactured from April and April for models being manufactured before April With the implementation of interior fitting regulation in India, it is mandatory that every manufacturer tests and certifies their product to comply with the energy dissipation standards as defined in the regulation ECE R Extensive interior fitting test program is carried out for various models ranging from MY to MY During the development testing following types of failures were observed: Occurrence of surface cracks due to sharp edges and component dislocation. High deceleration levels more than 80g continuously for 3ms experienced by the head form. Various counter measures such as material change, reduction in stress concentration area, design for energy absorption and other techniques were adopted to overcome these problems.
