req uest of the Dep rtment of Transport

This stand ard specifies req uirements for restraining sy stems for car y ing infants

up to a mas of13kg in roa v ehicles Because of their phy sical structure and

their ne d for prolong ed rest, b bies are best car ied in a semi reclned position,

facing the rear of the vehicle You g chi dren can be car ied in a simi ar mod e or

as BS325 -2:19 1 an ECE Reg ulation No.4

This edition of BSAU202 difer f om its predeces or in a n mber of important

respects Most nota ly, it defines two mas g roups and sets out specifications for

rear-facing sy stems for each g roup: up to10kg ( g roup0 d ev ices) and up to13kg

( g roup0 + dev ices) Dev ices ofeither g roup can be used on the font or rear seat

of most road v ehicles, as recommended b the man facturer of the restraint
