Overview

ISO 8124-4:2014 - Safety of toys: Part 4 defines safety requirements and test methods for activity toys intended for family domestic use (children under 14 years). It covers toys that are intended to bear the mass of one or more children and where movement is involved - for example swings, slides, seesaws, carousels, rocking toys, climbing frames, fully enclosed toddler swing seats, inflatable activity toys and paddling pools. The document consolidates earlier editions and amendments and is aligned with existing regional standards (e.g., EN 71‑8, ASTM F1148).

Key topics and technical requirements

• Scope and definitions: clear definitions for activity toys, free space, impact area, suspension connectors, inflatable activity toys and paddling pools (pools have a max water depth of 400 mm).
• Safety requirements covering mechanical and physical hazards:
  • Barriers, handrails and platforms to prevent falls
  • Rung ladders, stepladders and stairways design criteria
  • Entrapment - prevention of head, neck and limb entrapment
  • Stability of frames and assemblies (slides, swings, other structures)
  • Specific requirements for slides, swings, seesaws, carousels and rocking toys
  • Inflatable activity toys including construction and deflation considerations
  • Paddling pools and related static load/containment concerns
• Warnings, labelling and instructions: mandatory labelling, assembly, maintenance instructions and consumer warnings to support safe use and supervision.
• Test methods (Clause 6): prescribed laboratory tests such as stability tests, static and dynamic strength, impact testing for swing elements, head/neck entrapment tests, toggle and protrusion tests, suspension connector durability, deflation tests for inflatables and static load tests for paddling pools.
• Normative reference: ISO 8124‑1 (mechanical/physical properties) and informative annexes providing rationale, consumer guidance on surfacing and labelling guidelines.

Practical applications & who uses it

• Toy manufacturers and product designers use ISO 8124‑4 to design and validate safe activity toys for home use.
• Test laboratories and conformity assessors apply the specified test methods to certify compliance.
• Retailers and procurement teams reference the standard to specify safety requirements for products they sell.
• Regulators and safety officers use it when assessing domestic activity toy safety, though national requirements should also be checked.
• Useful for companies producing inflatable play equipment, backyard playsets, toddler swings and paddling pools to demonstrate product safety and reduce liability.

Related standards

• ISO 8124‑1 (mechanical and physical properties)
• EN 71‑8 and ASTM F1148 (regional equivalents referenced in the introduction)

Using ISO 8124‑4:2014 helps organizations manage toy safety risks, design compliant swings and slides, and follow harmonized test methods for domestic activity toys.

Introduction
This part of ISO 8124 is largely based upon existing standards in the European Union (EN 71-8) and in
the United States (ASTM F1148).
However, it should not be construed that a toy manufactured in compliance with this part of ISO 8124
will be in full compliance with relevant national toy safety requirements in the market where the
product is intended to be distributed. The user of this part of ISO 8124 is therefore advised to be aware
of relevant national requirements.
Compliance with the requirements of this part of ISO 8124 will minimize potential hazards associated
with toys resulting from their use in their intended play modes (normal use) as well as unintended play
modes (reasonable foreseeable abuse).
This part of ISO 8124 will not, nor is it intended to, eliminate parental responsibility in the appropriate
selection of toys. In addition, this part of ISO 8124 will not eliminate the need for parental supervision
in situations where children of various ages may have access to the same toy(s).

Swings, slides and similar activity toys for indoor and
outdoor family domestic use
1 Scope
This part of ISO 8124 specifies requirements and test methods for activity toys for domestic family use
intended for children under 14 years to play on or in.
Products covered by this part of ISO 8124 include swings, slides, seesaws, carousels, rocking toys,
climbing frames, fully enclosed toddler swing seats and other products intended to bear the mass of one
or more children.
Products not included within the scope of this part of ISO 8124 are:
a) fitness and sporting equipment unless attached to the activity toy;
b) equipment intended for use in schools, day care centres, kindergartens, public playgrounds,
restaurants, shopping centres and similar public places;
c) juvenile care products such as, but not limited to, infant swings, playpens/enclosures, beds or furniture
including picnic tables, cradle rockers and products specifically designed for therapeutic use.
Inflatable activity toys are included in the scope of this part of ISO 8124. However, a powered blower
used to continuously inflate the toy is not covered by this part of ISO 8124 since it is considered to be a
household appliance and covered by requirements given in IEC 60335-2-80.

4 Requirements
4.1 General
See A.4.1.
4.1.1 Static strength
Activity toys, other than swings, shall not collapse when tested in accordance with 6.2.1 (strength of
toys other than swings). After testing, the toy shall continue to comply with the relevant requirements
of this part of ISO 8124. Requirements for swings are given in 4.7 (swings).
4.1.2 Maximum height
See A.4.1.2.
There shall be no part of the activity toy designed to encourage the child to climb, sit on or stand on, with
a height of 2 500 mm or more when measured from the ground.
This does not include barriers, roofs, etc., that are not intended to be climbed, sat on or stood on.
Barriers, roofs, etc., that are not intended to be climbed shall be designed in such a way that climbing is
not encouraged.
4.1.3 Corners and edges
See A.4.1.3.
Exposed corners and edges shall be rounded.
Corners and exposed edges on moving parts shall have a minimum radius of 3 mm. This does not apply
to swing elements with a mass of 1 000 g or less, the corners and edges of which shall be rounded.
4.1.4 Protruding parts
4.1.4.1 General
Protruding parts (such as bolt ends and nuts) shall be recessed or be protected in such a way that they
do not constitute an entrapment hazard or other hazard to users.
If protrusions cannot be placed within the 50 mm outside diameter test gauge defined in 6.7.1 (all protrusions),
they are considered to be inaccessible and are exempted from these requirements (see Figure 6).
Rope protrusions are specifically exempted from the requirements of 4.1.4.

Figure 9 — Non-entrapment/protrusion zone and protrusion examples
Slides shall be constructed in such a way as to provide a smooth continuous sliding surface with no gaps
or spaces that might create an entrapment hazard such as, but not limited to, the space created between
sidewalls when two single slides are combined to create a doubly wide slide, or the point where a hood
is attached to the sidewalls of a slide. Roller slides are exempt from the requirements of this subclause.
See 4.6.4 (roller slides) for specific requirements for roller slides.
4.1.5 Climbing and swinging ropes, chains and cables
See A.4.1.5.
A suspended climbing rope, chain or cable shall be secured at both ends to prevent the rope, chain or
cable from being looped back on itself creating a loop with an interior perimeter of 130 mm (diameter
41,4 mm) or more.
A rope, chain or cable used to support a swing seat is exempt from these requirements.
4.1.6 Open tubing
All open tubing ends that are not resting on the ground or otherwise covered shall be provided with
caps or plugs that have a smooth finish and are tight-fitting. The protective cap or cover shall not become
detached when tested in accordance with the torque test and the tension test for protective components
specified in ISO 8124-1.
4.2 Barriers
See A.4.2.
Any platform intended for sitting or standing 760 mm or more above the ground shall be equipped with
a barrier on all sides that face outward from the toy.
Openings in barriers to give access to slides, climbing frames and ladders are allowed.
Barriers for platforms from 760 mm to 1 000 mm above the ground shall have a minimum height of 630 mm.
Barriers for platforms greater than 1 000 mm and up to 1 830 mm above the ground shall have a
minimum height of 720 mm.
Barriers for platforms more than 1 830 mm above the ground shall have a minimum height of 840 mm.
Barriers for platforms from 760 mm to 1 000 mm above the ground shall have a maximum vertical
opening of 610 mm between the lowermost member of the barrier and the platform that it surrounds.
Barriers for platforms more than 1 000 mm above the ground shall be designed to minimize the
likelihood of climbing. Openings within these barriers or between the barrier and the platform surface
shall not permit the passage of the torso probe defined in 6.5.1 (head and neck entrapment in completely
bound openings).
For barriers with an uneven top design, a straightedge of (200 ± 5) mm shall be used for measuring
minimum height. Place the straightedge horizontally on top of the barrier. Measure the vertical distance
between the platform and the bottom of the straightedge. The distance shall in no place be less than the
minimum heights specified in this part of ISO 8124.
NOTE Special requirements apply to slides (see 4.6.2 (retaining sides for slides) and 4.6.3 (starting, sliding
and run-out section on slides)).
10 © ISO 2014 – All rights reserved

When tested in accordance with 6.3 (dynamic strength of barriers and handrails), no part of the
barrier or handrail shall collapse, such that the toy does not comply with the relevant requirements of
this part of ISO 8124.
4.3 Rung ladders, stepladders and stairways
These requirements do not apply to toys with a platform height of 600 mm or less.
Rung ladders, stepladders and stairways shall comply with the following requirements.
a) The rung or tread shall have a substantial horizontal stepping surface with a lateral width of 240 mm
or more (see Figure 10).
b) The distance between the upper surface of the rungs or treads on rung ladders or stepladders
shall not be more than 310 mm and on stairways not more 230 mm when measured vertically in
accordance with Figure 10.
c) The surface of the tread shall not be slippery.
NOTE This can be achieved by corrugation of the tread or by use of non-slip materials.
d) The diameter or cross-sectional dimension of the rungs on rung ladders shall be at least 16 mm but
not more than 45 mm. Care should be taken when using designs other than circular cross-sections
to ensure that gripping potential is not seriously impaired.
e) The depth of treads on stepladders with closed risers or stairways shall be 180 mm or more.
f) The inclination of stairways shall not be more than 50°. The inclination of stepladders shall not be
less than 65° and not more than 75°. The inclination of rung ladders shall not be less than 60° and
not more than 90°.
g) Stairways and stepladders with a height of 1 200 mm or more above the ground shall be provided
with a means of continuous hand support from a height of 760 mm (see Figure 10).

4.4 Entrapment
See A.4.4.
4.4.1 Head and neck entrapment
These requirements do not apply to openings where the ground forms the lower boundary.
Activity toys shall be constructed so that no openings create head and neck entrapment hazards either
by head first or feet first passage.
NOTE Hazardous situations in which this type of entrapment can be encountered include the following:
— completely bound openings through which a user can slide head first or feet first;
— partially bound or V-shaped openings;
— shearing and moving openings.

When choosing materials, the manufacturer shall take into account the entrapment hazards that can
occur due to distortion of material during use.
a) Accessible completely bound openings shall also allow passage of probe D (Figure 26) if they allow
passage of probe C (Figure 25) when tested in accordance with 6.5.1 (test for head and neck entrapment).
b) Accessible rigid openings shall not allow the passage of probe E (Figure 27) unless they also allow
the passage of probe D when tested in accordance with 6.5.1.
c) Partially bound and V-shaped openings shall be constructed so that either:
1) the opening is not accessible as illustrated in Figure 29 and when tested in accordance with
6.5.2.3 a); or
2) the tip of the template contacts the base of the opening when tested in accordance with 6.5.2.3 b);
d) Openings between flexible parts of suspended bridges and any rigid side members shall allow the
passage of probe D (Figure 26) under the worst-case condition of loading. Both loaded and unloaded
situations shall be tested.
e) Non-rigid members (e.g. ropes) shall not overlap if by doing so they create openings that do not
comply with the requirements in a).
f) A shield intended to make inaccessible any opening that would otherwise fail the requirements of
a) to e) shall
1) be constructed of a rigid material;
2) not fracture, fail or be displaced in a manner that will allow the opening to become accessible
when impacted by a 127 mm diameter steel ball with 27 J at a point within 25 mm of the
geometric centre of the shield;
3) not fracture, fail or be displaced in a manner that will allow the opening to become accessible
when tested in accordance with the torque and tension tests of ISO 8124-1.
4.4.2 Entrapment of clothing and hair
Hazardous situations in which clothing or hair can be entrapped may be created by:
a) gaps or V-shaped openings in which parts of clothing can become entrapped while or immediately
before the user undergoes a forced movement;
b) protrusions;
c) rotating parts.
