European foreword
This document (EN 1888-1:2018+A1:2022) has been prepared by Technical Committee CEN/TC 252
“Child care articles”, the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by October 2022, and conflicting national standards shall
be withdrawn at the latest by October 2022.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes !EN 1888-1:2018".
This document includes Amendment 1 approved by CEN on 01 January 2022.
The start and finish of text introduced or altered by amendment is indicated in the text by tags !".
In comparison with this EN 1888:2012, the significant technical changes relate to the following issues:
a) chemical hazards;
b) entrapment hazards;
c) hazards from moving parts;
d) entanglement hazards;
e) parking device test method;
f) stability of the vehicle;
g) introduction of an informative Annex E giving relevant translations for warning sentences;
h) introduction of an informative Annex D giving information on the assessment of moving parts of
canopies;
i) introduction of an informative Annex G giving information on the arrangement of approval marks for
car seats.
In November 2014, the European Working Group decided to split EN 1888 into different parts to clearly
treat in a different way, new products or new functions of wheeled child conveyances.
EN 1888 is currently composed with the following parts:
— EN 1888-1, Child care articles — Wheeled child conveyances — Part 1: Pushchairs and prams;
— EN 1888-2, Child care articles — Wheeled child conveyances — Part 2: Pushchairs for children above
15 kg up to 22 kg.
EN 1888 therefore becomes EN 1888-1 and is only applicable to pushchairs and prams. It will be used as
a reference in future parts.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United
Kingdom.

4 General requirements and test conditions
NOTE Words in italics are defined in Clause 3 (Terms and definitions). Additional information on the
background and rationale for various requirements is given in Annex A.
4.1 Samples
Tests should be carried out in the order of the clauses given in this European standard, unless otherwise
stated. Each test shall be carried out only using one vehicle, unless otherwise stated.
Vehicles with multiple places for pram bodies and/or seat units shall comply with all applicable
requirements in any possible arrangement in accordance with the manufacturer's instructions. If a
vehicle can be equipped with an additional seat unit or pram body or type A/B car seat supplied or
recommended by the manufacturer, the combination shall comply with this European Standard.
4.2 Principle of the most onerous condition
Unless otherwise stated each test shall be conducted with the vehicle in the most onerous condition for
that test in terms of:
— the choice and number of seat units and/or pram bodies and/or car seats attached to the chassis stated
in the manufacturer's instructions;
— the addition of any additional seat unit(s) approved by the manufacturer;
— the use of test masses: for vehicles transporting more than one child, at least one place that a child
can occupy shall be loaded with a test mass;
— the loading (or not) of any receptacle designed for carrying additional load(s) allowed for in the
instructions or otherwise approved by the manufacturer and the placing (or not) of load(s) in any
such facility, up to the maximum mass allowed in the manufacturer's instructions, or 2 kg if nothing
is indicated; small pockets fitted onto textile parts are not concerned by this condition;
— the addition (or not) of any other accessories supplied or recommended by the manufacturer for use
with the vehicle and with accessories loaded according to the manufacturers instructions;
— the adjustment of seat units, pram bodies, handles, car seats, and any other adjustable features or
accessories, or any other optional arrangement of the vehicle allowed in the manufacturer's
instructions or otherwise approved by the manufacturer.
NOTE The heaviest loads do not always produce the most onerous conditions.
4.3 Tolerances for test equipment
Unless otherwise stated, the accuracy of the test equipment shall be:
— forces ± 5 %;
— masses ± 0,5 %;
— dimensions ± 0,5 mm;
— timing ± 1 s;
— angles ± 0,5°.
4.4 Test conditions
The vehicle shall be conditioned at a temperature of (23 ± 5) °C for at least 2 h prior to tests. All tests shall
be carried out at a temperature of (23 ± 10) °C unless otherwise specified.
For vehicles fitted with inflatable tyres, the tyre pressure shall be adjusted according to manufacturer’s
instructions for use before conducting the entire test procedure. If a tyre is punctured during the test
procedure, the tyre shall be replaced and the test procedure continued.
4.5 Determination of the protected volume
4.5.1 Protected volume of seat units
The protected volume of seat units shall be determined in accordance with Figure 1 below.
EN 1888-1:2018 (E)
Dimensions in millimetres
Key
1 origin from which the protected volume has been defined (mid-point of the junction line, on the uncompressed
upper surface of the seat unit)

The space underneath the seat and underneath the leg rest is excluded from the protected volume, except
for a 50 mm wide band measured from the outermost edge of the seat/leg rest sides where the seat/leg
rest is not fitted with lateral protections of a height greater than 50 mm (textile or any rigid component)
(see Figure 2).

5 Test equipment
5.1 Test masses
5.1.1 General
Unless otherwise specified, the test masses shall be those given in 5.1.2 to 5.1.9.
Any damage to fabric which may occur as a result of abrasion by the test masses during tests shall be
ignored. Damage can be minimized by using a convenient means of protection of negligible mass. Where
damage is not caused by abrasion by the test masses it constitutes a structural failure.
Test masses may be fitted with additional handles for carrying purposes, as long as the centre of gravity
is not changed and mass remains within tolerances and the test procedure is not affected.
5.1.2 Test mass A
Test mass A is a rigid cylinder (160 ± 5) mm in diameter and (300 ± 5) mm in height, having a mass
of (9 + 0, 1/0) kg and with its centre of gravity in the centre of the cylinder. All edges shall have a radius
of (5 ± 1) mm. Two anchorage points shall be provided, positioned (150 ± 2,5) mm from the base and
at 180° to each other around the circumference as shown in Figure 9.
