Overview

prEN 1888-1: Child Care Articles - Wheeled Child Conveyances - Pushchairs and Prams is a draft European Standard developed by CEN (European Committee for Standardization). It sets out safety requirements and test methods for pushchairs and prams designed for the transportation of one or more children, with each child weighing up to 22 kg and any integrated standing platform supporting up to 20 kg. This standard aims to ensure both child safety and product reliability within the European market.

prEN 1888-1:2026 is part of the broader EN 1888 series, designed to harmonize child care product safety across the European Union and EFTA member states. It supersedes previous standards EN 1888-1:2018+A1:2022 and EN 1888-2:2018+A1:2022.

Key Topics

• Scope and Definitions

  • Applies to manually operated pushchairs and prams, including those with multiple seats or platforms.
  • Excludes toys, wheeled baby carriers, motorized vehicles, and conveyances for children with special needs.

• Safety Requirements

  • Specifies requirements for structural integrity, stability, entrapment prevention, and resistance to mechanical hazards.
  • Covers restraint systems, parking and braking devices, and hazards related to choking, suffocation, exposure to chemicals, and thermal risks.

• Test Methods

  • Standardizes procedures for evaluating durability, occupant space, and protected volumes.
  • Addresses worst-case scenarios for product configuration, usage, and loading.

• Marking and Instructions

  • Details requirements for product labeling, consumer information, purchase guidance, and usage instructions to promote safe handling and operation.

Applications

The practical application of prEN 1888-1:2026 is critical for:

• Manufacturers: Ensuring all new pushchair and pram models brought to the European market meet stringent safety and performance requirements. This reduces recall risks and enhances consumer trust.
• Importers and Retailers: Verifying compliance of products before sale. Demonstrating conformance to prEN 1888-1 helps fulfill obligations under EU legislation.
• Testing Laboratories: Providing consistent criteria for product testing, certification, and quality control throughout the EU and associated markets.
• Product Designers: Integrating safety principles, including hazard prevention and structural durability, into the engineering of new models.
• Consumers: Enabling easier identification of compliant products, which assures a baseline level of safety for infants and young children.

By following prEN 1888-1, stakeholders help ensure that wheeled child conveyances meet or exceed recognized safety benchmarks, protecting children while providing confidence to caregivers and regulators alike.

Related Standards

• EN 1888-3: Wheeled child conveyances for leisure sport activities.
• EN 1466: Carry cots and stands for domestic use - Safety requirements and test methods.
• EN 17826: Child care articles - Chemical hazards - Requirements.
• EN 71-2: Safety of toys - Flammability.

Ensuring conformity with prEN 1888-1 and associated standards supports the wider objectives of the EU General Product Safety Regulation (2023/988/EU).

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 Material suitability
Different weather conditions during the usage of the product can influence the material performances.
Annex E provides general guidance on the choice of materials.
4.2 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 carry cots 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, the combination shall comply with this European Standard.
4.3 Principle of the most onerous condition
Unless the test method gives specific indications for any of the following topics, 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 carry cots 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 placement of the test masses on the seat
units and/or pram bodies and/or carry cots and/or car seats shall be carried out in the most onerous
condition, regardless of the manufacturer’s instructions;
— 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; such loads shall be evenly distributed on the loading support surface in the receptacle
(e.g. sandbags, etc.); 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 manufacturer’s instructions;
— the adjustment of seat units, pram bodies, handles, car seats, and any other adjustable features or
accessories (with exception of the backrest inclination), 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.
4.4 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°.
4.5 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 (21 ± 6) °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.

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 or hooks for specific test
methods, as long as the centre of gravity is not changed and mass remains within tolerances and the test
procedure is not affected.
