EXAMPLE Designation of a seat to be mounted behind the rider (A), maximum load 15 kg (15): Child seat A15.

4.2 Principle of the most onerous condition
All tests shall be conducted according instructions for use.
It is allowed to use any cycle that is suitable according to this information.

Unless otherwise stated each test shall be conducted with the child seat in the most onerous condition

for that test in terms of:

— the addition (or not) of any other accessories supplied or recommended by the manufacturer for use

with The child seat and with accessories loaded according to the manufacturer's instructions;

— the adjustment of the child seat, and any other adjustable features (e.g. reclined backrest) or

accessories, or any other optional arrangement of the child seat allowed in the manufacturer's

instructions or otherwise approved by the manufacturer;
— any removable padding shall be installed during the measurements.
NOTE The heaviest loads do not always produce the most onerous conditions.
4.3 Tolerances and test conditions

Unless otherwise stated the following tolerances shall be used: All forces shall have an accuracy of ± 5 %.

carried out at a temperature of (23 ± 5) °C unless otherwise specified.
4.4 Order of tests

The test shall be carried out in the order that they appear in this document. All tests shall be performed

on one seat.
Following tests shall be tested in the order that they appears in this standard:

European foreword

This document (prEN 14344:2020) has been prepared by Technical Committee CEN/TC 252 “Child use

and care articles”, the secretariat of which is held by AFNOR.
This document is currently submitted to the second CEN Enquiry.
This document will supersede EN 14344:2004.

This document has been prepared under a mandate given to CEN by the European Commission and the

European Free Trade Association, and supports essential requirements of EU Directive(s).

1 Scope

This document specifies requirements for child seats intended to be mounted on cycles and electrical

power assisted cycles with a cut off speed of up to 25 km/h (i.e. according to EN 15194), their attachment

system and accessories intended to be attached to the seat in order to transport children with a weight

from 9 kg up to 22 kg and who are capable of sitting unaided.

NOTE 1 Some European countries have special legislation for child seats for cycles. Compliance with this

document might not meet this legislation.

NOTE 2 Where a child seat or any part of the child seat has several functions or can be converted into another

function, other relevant standards might be applicable.

It is allowed to use any cycle that is suitable according to this information.

Unless otherwise stated each test shall be conducted with the child seat in the most onerous condition

for that test in terms of:

— the addition (or not) of any other accessories supplied or recommended by the manufacturer for use

with the child seat and with accessories loaded according to the manufacturer's instructions;

— the adjustment of the child seat, and any other adjustable features (e.g. reclined backrest) or

accessories, or any other optional arrangement of the child seat allowed in the manufacturer's

instructions or otherwise approved by the manufacturer;
— any removable padding shall be installed during the measurements.
NOTE The heaviest loads do not always produce the most onerous conditions.
4.3 Tolerances and test conditions
Unless otherwise stated the following tolerances shall be used:
All forces shall have an accuracy of ± 5 %.
All masses shall have an accuracy of ± 1 %.
All dimensions shall have an accuracy of ± 1,0 mm.
All time measurements shall have an accuracy of ± 1s.

All frequencies, amplitudes shall have an accuracy of ± 5 %.

The seat shall be conditioned at a temperature of (23 ± 10) °C for at least 2 h prior to test. All tests shall

be carried out at a temperature of (23 ± 10) °C unless otherwise specified.
4.4 Order of tests

The tests shall be carried out on the same sample in the order that they appears in 8.8 of this document.

A separate sample could be used for all other tests.
