4 General requirement and test condition
4.1 Preliminary preparation

The furniture shall be tested as delivered. The furniture shall be assembled and/or configured

according to the instructions supplied with it. Unless otherwise stated the most adverse configuration

shall be used for each test. If mounting or assembly instructions are not supplied, the mounting or

assembly method shall be recorded in the test report. Fittings shall be tightened before testing and shall

not be re-tightened unless specifically required in the manufacturer’s instructions. If the configuration

must be changed to produce the worst-case conditions, this shall be recorded in the test report.

Unless otherwise specified by the manufacturer, the sample for test shall be stored in indoor ambient

conditions for at least 24 h immediately prior to testing.

The tests shall be carried out in indoor ambient conditions at a temperature between 15 °C and 25 °C. If

during a test the temperature is outside of the range of 15 °C to 25 °C, the maximum and/or minimum

temperature shall be recorded in the test report.

Before beginning the testing, visually inspect the unit thoroughly. Record any defects so that they are

not assumed to have been caused by the tests.
4.2 Application of forces

The test forces in durability and static load tests shall be applied sufficiently slowly to ensure that

negligible dynamic load is applied. The forces in durability tests shall be applied sufficiently slowly to

ensure that kinetic heating does not occur.

Unless otherwise stated, static forces shall be maintained for (10 ± 2) s. Unless otherwise stated,

durability forces shall be maintained for (2 ± 1) s.

The forces may be replaced by masses. The relationship 10 N = 1 kg shall be used.

4.3 Tolerances

Unless otherwise stated, the following tolerances are applicable to the test equipment:

— Forces: ± 5 % of the nominal force;
— Velocities: ± 5 % of the nominal velocity;
— Masses: ± 1 % of the nominal mass;
— Dimensions: ± 1 mm of the nominal dimension;
— Angles: ± 2° of the nominal angle.

The accuracy for the positioning of loading pads and impact plates shall be 5 mm.

NOTE For the purposes of uncertainty measurement, test results are not considered to be adversely affected

when the above tolerances are met.

5.5 Additional loading position template

In derogation to EN 1728:2012+AC:2013 and EN 1022:2005, the loading position template for seating

with seat and back made of one suspended or hanging piece of flexible material (e.g. textile) shall be a

cylinder with a mass of (1 ± 0,5) kg and a diameter of (70 ± 10) mm.
6 General safety requirements
6.1 Glass (see B.3)
There shall be no glass in children's seating.
6.2 Edges and corners

All parts shall be so designed that physically injury and damage are avoided. This requirement is

fulfilled when:

— edges of the seat, back rest and arm rests, which are in contact with the user when sitting in the

chair are rounded with a minimum 2 mm radius or chamfer;

— edges of the handles are rounded with a minimum 2 mm radius in the direction of the force applied;

— all other edges and corners are smooth, rounded or chamfered and with no burrs.

6.3 Entrapment hazards (see B.4)
6.3.1 Finger entrapment hazards
6.3.1.1 Requirements

There shall be no completely bounded, circular openings in rigid materials between 7 mm and 12 mm

unless the depth is less than 10 mm when tested in accordance with 6.3.1.2 and/or completely bounded

oval openings where the largest dimension is smaller than 12 mm and where the smallest dimension is

greater than 7 mm.

The size of the holes in mesh shall be less than 7 mm when measured in accordance with 6.3.1.2.

6.3.1.2 Test methods

Check whether the 7 mm finger probe (5.1.1) with an applied force of up to 30 N, enters 10 mm or more

into any open ended tubes and completely bounded circular openings in any possible orientation. If the

7 mm finger probe enters 10 mm or more then the 12 mm finger probe (5.1.1) must also enter 10 mm

or more with an applied force of up to 5 N.

Check whether the conical probe (5.1.2), penetrates holes in the mesh to the 7 mm diameter section

with an applied force of up to 30 N.
6.3.2 Partially bound, V and irregular shaped openings
6.3.2.1 Requirements
The following requirements apply to size 1 seats only.

Partially bound and V-shaped openings with a lower edge ≥ 600 mm above the ground shall be

constructed that when tested in accordance with 6.3.2.2 either:

a) portion B of the V and irregular shaped openings template does not enter the opening; or

---------------------- Page: 13 ----------------------
oSIST prEN 17191:2018
prEN 17191:2017 (E)

b) the apex of portion A of the V and irregular shaped openings template contacts the base of the

opening.
6.3.2.2 Test method

Position the B portion of the V and irregular shaped openings template (see 5.2) between and

perpendicular to the boundaries of the opening (see Figure 7, Figure 8 or Figure 9 as appropriate).

If the full thickness of the template cannot be inserted there is no hazard, but if it can be inserted there

is a hazard, see Figure 7, Figure 8 or Figure 9.

If the V and irregular shaped openings template can be inserted to a depth greater than the thickness of

the template (45 mm), apply the A portion of the V and irregular shaped openings template, so that its

centre line is in line with the centre line of the opening. Ensure that the plane of the test template is

parallel and applied in line with the opening (see Figure 7). Insert the V and irregular shaped openings

template along the centre line of the opening until its motion is arrested by contact with the boundaries

of the opening.

If the V and irregular shaped openings template touches the bottom of the opening there is no hazard,

but if the sides of the template touch the sides of the opening there is a hazard (see Figure 7).

4 General requirement and test condition
4.1 Preliminary preparation

The seating shall be tested as delivered. Knock-down seating shall be assembled according to the

manufacturer’s instructions. If the instructions allow the seating to be assembled or combined in different

ways, the most adverse combination shall be used for each test. Knock-down fittings shall be tightened

before testing. Further tightening shall not take place unless specifically required by the manufacturer. If

the configuration shall be changed to produce the worst-case conditions, this shall be recorded in the test

report.

Unless otherwise specified by the manufacturer, the sample for test shall be stored in indoor ambient

conditions for at least 24 h immediately prior to testing.

The tests shall be carried out at indoor ambient conditions. However, if during a test the temperature is

outside the range 15 °C to 25 °C, the maximum and/or minimum temperature shall be recorded in the

test report.

Before beginning the testing, visually inspect the unit thoroughly. Record any defects so that they are not

assumed to have been caused by the tests.
4.2 Application of forces

The test forces in durability and static load tests shall be applied sufficiently slowly to ensure that

negligible dynamic load is applied. The forces in durability tests shall be applied sufficiently slowly to

ensure that kinetic heating does not occur.
Unless otherwise stated:
— static forces shall be maintained for (10 ± 2) s
— durability forces shall be maintained for (2 ± 1) s.

The forces may be replaced by masses. The relationship 10 N = 1 kg shall be used.

oSIST prEN 17191:2019
prEN 17191:2019 (E)
4.3 Tolerances

Unless otherwise stated, the following tolerances are applicable to the test equipment:

— Forces: ± 5 % of the nominal force;
— Velocities: ± 5 % of the nominal velocity;
— Masses: ± 1 % of the nominal mass;
— Dimensions: ± 1 mm of the nominal dimension;
— Angles: ± 2° of the nominal angle.

The accuracy for the positioning of loading pads and impact plates shall be 5 mm.

NOTE For the purposes of uncertainty measurement, test results are not considered to be adversely affected

when the above tolerances are met.
4.4 Sizes
The seating shall be tested with reference to the seat height, see Table 1.
Table 1 — Seating sizes
Dimensions in millimetres
Size Size 1 Size 2 Size 3
Seat height (h) h ≤ 260 260 < h ≤ 350 h > 350

NOTE Information on seating sizes and the age/size of children is contained within Annex A.

For seating where it is not possible to determine a size (e.g. bean bags), they shall be tested as size 1 for

all tests, except the strength and durability tests for which they shall be tested as size 3.

4.5 Accessibility

For the purpose of the standard, all parts of the seating are considered accessible to the child.

4.6 Testing range of seating

If seating in a range of sizes are all manufactured with identical construction details, or if the seating can

be adjusted to different heights, it is only necessary to carry out the complete strength, durability and

stability tests on the highest size in the range or in the highest position, plus additional stability tests on

the smallest size in the range or the lowest position. In the event of failure of any seating in the above test

programme, the complete test programme shall be carried out on each seating size mark individually.
