In the mid-seventies, the United Nations' group of experts on passive safety started to work on requirements for child restraint systems. The work resulted in ECE-Regulation 44: "Uniform provisions concerning the approval of restraining devices for child occupants of power-driven vehicles" that entered into force in 1982. An ad-hoc group was asked to develop a series of child dummies for this regulation. Originally, the regulation described 4 child dummies including the P¾ (9 months), P3 (3 years), P6 (6 years), and P10 (10 years). In 1988, a 5th dummy was added representing a newborn child, the P0 and in 1995 the 18-month-old child dummy was developed (P1½).

These six dummies are known as the TNO P-series of child dummies. The dimensions and mass distribution of the dummies represent those of 50th percentile children of their respective ages.

P-Dummies are designed in 6 sizes; P0 Newborn, P¾ 9MO, P1½ 18MO, P3 3YO, P6 6YO, P10 10YO
