The Q Series of dummies covers the Q0, Q1, Q1.5, Q3, Q3s, Q6 and Q10, each on based on the 50th percentile of children with the respective age. Q Dummies are used in safety testing by EuroNCAP and given a child seat rating, whilst more recently the European regulation ECE R129 was brought in to further promote the use of enhanced child restraint systems.
The Q3 Dummy accurately represents an average 3 year old child and is used for crash testing applications. The dummy is positioned in cars to test occupant safety and used in a range of sled tests for harness and safety belt evaluation.
