UN R145: Proposal for Supplement 3

Reference Number: GRSP-73-25/Rev.1

Proposal to reflect the size ranges used in UN R129, OICA suggests using the stature of 100 cm (which is approximately a child weighing 18 kg). This would be aligned with the requirement that non-integral ECRS are not allowed for children with a stature of less than 100 cm (6.1.3.3.) and also with the requirement for toxicity testing in 6.3.1.1 (para 6.3.1.1 does not apply to non-integral ECRS with a stature range of 100 cm or above).
