Overview

ISO 7170:2021 - "Furniture - Storage units - Test methods for the determination of strength, durability and stability" defines standardized test methods for assessing storage furniture when fully assembled prior to use. It covers both movable and non‑movable parts (shelves, doors, extension elements, castors, etc.). The standard provides detailed procedures for applying forces, loading, tolerances, test apparatus and reporting, but does not set pass/fail acceptance criteria. Instead, Annex B supplies suggested loads, cycles and forces (for example for domestic use), while Annex A gives guidance on choosing appropriate test parameters.

Key technical topics and requirements

• General test conditions: preparation, force application, prevention of movement and measurement tolerances.
• Test equipment and apparatus: specifications for jigs, loading devices and slam‑shut apparatus.
• Non‑movable parts: tests for shelves (retention, deflection, shelf support strength), tops/bottoms (sustained/static loads), clothes rails and structural strength (underframes, legs, drop tests).
• Movable parts: pivoted doors, sliding doors, roll fronts, flaps and extension elements - strength, durability, slam‑shut/open and interlock tests.
• Locking/latching mechanisms: strength and durability tests for locks and latches.
• Other elements: trays, coat hooks, units mounted to the building or floor, and castor/wheel behaviour.
• Stability testing: comprehensive stability procedures including unloaded/loaded conditions, opening of doors/extension elements, dynamic tests for castored units and anti‑overturning device strength.
• Documentation: required content of the test report.
• Informative annexes (Annex C rationale; Annex D apparatus) explain test selection and specific equipment.

Practical applications - who uses ISO 7170

• Furniture manufacturers and designers: validate product strength, durability and stability during development.
• Independent test laboratories and certification bodies: perform reproducible tests for technical files and conformity assessment.
• Retailers and specifiers: verify supplier claims and support product selection for safety and performance.
• Regulators and safety assessors: reference test methods for consumer protection and accident investigation.
• Procurement and contract furniture buyers: specify test methods in tenders and quality requirements.

Applying ISO 7170 helps reduce product failures, improve consumer safety (anti‑overturning performance), and provide consistent, reproducible test evidence for marketing or compliance purposes.

Related standards

Consult other ISO furniture and safety standards and relevant national regulations for complementary test criteria and acceptance limits. Annex B of ISO 7170 gives suggested loads for domestic use; users should adapt loads and acceptance criteria to market, application and regulatory requirements.

Introduction
This document has been developed with the objective of promoting relevant test methods for
determining the strength, durability and stability of storage furniture, simulating normal functional
use, as well as foreseeable misuse, that might reasonably be expected to occur. The tests are designed to
evaluate properties without regard to materials, design/construction or manufacturing processes and
intended to demonstrate the ability of the item to give satisfactory service in its intended environment.
The test results are only valid for the unit/component tested. These results can be used to represent
the performance of production models prior to use, provided that the tested unit/component is
representative of the production model. Only when properly justified, they can be used for failure
analysis of a unit that has been in use.
The strength and durability tests do not assess the structure of the building, e.g. the strength of wall
hanging cabinets includes only the cabinet and the parts used for the attachment. The wall and the
attachment into the wall are not included.
Assessment of ageing and environmental degradation is not included.

4 General test conditions
4.1 Preliminary preparation
The unit(s)/component(s) shall be tested as delivered. The unit(s)/component(s) shall be assembled
and/or configured according to the instructions supplied. Unless otherwise stated, the most adverse
configuration (3.8) 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 needs to be changed in order to produce the worst-case (3.26) conditions, this shall
be recorded in the test report.
During testing, the unit shall be placed on the floor and levelled, unless otherwise specified. The
levelling device (3.18) shall be set to the mid position but not more than 13 mm from fully closed.
A combination of tests can be necessary to cover the properties of multifunction components (e.g. a
receding door shall be tested both as a sliding door and as a pivoted door).
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 27 °C. If
during a test the temperature is outside of the range of 15 °C to 27 °C, the maximum and/or minimum
temperature shall be recorded in the test report.
In addition, the test for deflection of shelves (6.1.4) and sustained load tests (6.2.1) except metal, stone
and glass shelves, shall be carried out at a relative humidity of 45 % to 55 %. If during a test the relative
humidity is outside this range, the maximum and/or minimum shall be recorded in the test report.
4 © ISO 2021 – All rights reserved

If a test cannot be carried out as specified (e.g. because a loading pad cannot be used for the application
of a force due to the design of a product), the test shall be carried out as closely as possible to that
specified.
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. Carry out measurements, if specified.
It is not necessary that all tests be carried out on the same unit, but all tests specified for a particular
component shall be carried out on the same component.
In Annex C, rationale for selected test methods is provided.
4.2 Application of forces
The test forces shall be applied sufficiently slowly to ensure that negligible dynamic force is applied.
Unless otherwise specified, each specified force shall be maintained for not less than 10 s and not more
than 15 s.
The test forces in durability tests shall be applied at a rate to ensure that excessive heating (3.11) does
not occur. Unless otherwise specified, each test force shall be maintained for (2 ± 1) s.
Forces shall be applied in a manner that ensures normal functioning of self-closing and damping
mechanisms. The forces can be replaced by masses. The relationship 10 N = 1 kg shall be used.
In Annex B, loads, forces and cycles are suggested to ensure that the test methods are of use where
no requirements document is available, or to assist in the development of one. See also Annex A for
guidance to develop requirements documents.
4.3 Tolerances
Unless otherwise stated, the following tolerances are applicable to the test equipment:
— forces: ± 5 % of the nominal force;
— velocities: ± 10 % of the nominal velocity;
— masses: ± 1 % of the nominal mass;
— dimensions: all dimensions less than 200 mm shall have an accuracy of ± 1 mm of the nominal
dimension; the other dimensions shall have an accuracy of ± 0,5 %; the dimension of the spherical
curvature of 300 mm radius on the loading pad (5.5) shall have an accuracy of ± 5 mm;
— angles: ± 2° of the nominal angles.
The accuracy for the positioning of loading pads shall be ± 5 mm.
Test forces, masses, dimensions, velocities and angles used to perform the test shall be targeted at the
nominal values specified and shall be subjected to the above tolerances.
NOTE For the purposes of uncertainty measurement, test results are not considered to be adversely affected
when the above tolerances are met.
4.4 Prevention of movement during test
If a free-standing unit (3.14) tends to overbalance during the tests specified in Clauses 6 and 7, load the
unit until this tendency stops, unless otherwise specified.
If a free-standing unit tends to slide during the tests specified in Clauses 6 and 7, with the exception of
6.4.2 and 6.4.3, the unit shall be restrained by stops (5.4).
4.5 Loading
Unless otherwise specified, for strength and durability tests, all storage components that are not
subject to testing shall be uniformly loaded according to Table 1.
Table 1 — Loads for strength and durability tests
Component Load
All horizontal storage areas, including shelves, bottoms, tops and flaps 0,65 kg/dm

5 Test equipment and apparatus
5.1 Unless otherwise specified, the tests can be applied by any suitable device, because results are
dependent only upon correctly applied forces and not on the apparatus.
The equipment shall not inhibit deformation of the unit/component, i.e. it shall be able to move so that
it can follow the deformation of the unit/component during testing, so that the loads are always applied
at the specified points and in the specified directions.
5.2 Floor surface, a rigid, horizontal and flat surface.
5.3 Wall surface, shall be rigid, vertical and flat.
5.4 Stops, devices to prevent the article from sliding but not tilting, not higher than 12 mm, except in
cases where the design of the unit necessitates the use of higher stops, in which case the lowest stop that
prevents the item from moving shall be used. For stability tests, the lowest height that prevents the item
from moving shall be used.

5.5 Loading pad, a rigid disc 100 mm in diameter, with a flat face and a 12 mm front edge blend radius.
Where space prevents the use of a 100 mm diameter loading pad, a 50 mm diameter loading pad with
similar properties can be used.
5.6 Apparatus for slam shut/open of extension elements, as given in Annex D.
5.7 Masses, shall be designed so that they do not reinforce the structure or re-distribute the stresses.
NOTE For the deflection of shelves (6.1.4), steel masses with a mass of 1 000 g and with a length of 85 mm, a
width of 50 mm, and a thickness of 30 mm are suitable.
5.8 Spherical objects, such as glass marbles with 10 mm to 15 mm diameter. They shall be loosely
packed in a flexible bag large enough to allow them to move in the bag during the test.
NOTE A bag that is approximately 50 % filled is considered loosely packed.
5.9 Loads for suspended filing pockets (3.24), shall be loaded with paper or an equivalent alternative
as shown in Figure 21.
5.10 Steel impact plates, 200 mm in length, with one surface faced with a 3 mm thick layer of rubber
with a hardness of (85 ± 10) IRHD according to ISO 48-5:2018. Other properties of steel impact plates
are as defined in Table 3.

5.11 Obstacles for castor durability tests, use two steel strips 50 mm wide and 2 mm high with the
edges having a radius of 2 mm, 500 mm apart and parallel on the floor surface and perpendicular to the
test direction.
5.12 TV Template, two templates constructed as frame or box as shown in Figure 2, with dimensions
as defined in Table 4, able to support a load acting through the centre of gravity of the TV template. The
weight of the unloaded template shall be (10 ± 0,2) kg.
The centre of gravity of the unloaded template shall be the geometric centre of the unloaded template.
When a load is added to the template, the variation of the position of the centre of gravity to that of the
unloaded template shall be restricted to 5 mm.
When testing, the template shall remain in its initial position.

6.1 Shelves
6.1.1 General
For units with an indeterminate number of shelves, unless otherwise specified, divide the internal
height of the unit, in millimetres, by 200 and take the nearest integer. This number, minus one, shall
then be the number of shelves to be fitted.
The number of shelves (N) that shall be fitted is calculated by the following formula:

Introduction
This document has been developed with the objective of promoting relevant test methods for
determining the strength, durability and stability of storage furniture, simulating normal functional
use, as well as foreseeable misuse, that might reasonably be expected to occur. The tests are designed to
evaluate properties without regard to materials, design/construction or manufacturing processes and
intended to demonstrate the ability of the item to give satisfactory service in its intended environment.
The test results are only valid for the unit/component tested. These results can be used to represent
the performance of production models prior to use, provided that the tested unit/component is
representative of the production model. Only when properly justified, they can be used for failure
analysis of a unit that has been in use.
The strength and durability tests do not assess the structure of the building, e.g. the strength of wall
hanging cabinets includes only the cabinet and the parts used for the attachment. The wall and the
attachment into the wall are not included.
Assessment of ageing and environmental degradation is not included.

4 General test conditions
4.1 Preliminary preparation
The unit(s)/component(s) shall be tested as delivered. The unit(s)/component(s) shall be assembled
and/or configured according to the instructions supplied. Unless otherwise stated, the most adverse
configuration (3.8) 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 needs to be changed in order to produce the worst-case (3.26) conditions, this shall
be recorded in the test report.
During testing, the unit shall be placed on the floor and levelled, unless otherwise specified. The
levelling device (3.18) shall be set to the mid position but not more than 13 mm from fully closed.
A combination of tests can be necessary to cover the properties of multifunction components (e.g. a
receding door shall be tested both as a sliding door and as a pivoted door).
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 27 °C. If
during a test the temperature is outside of the range of 15 °C to 27 °C, the maximum and/or minimum
temperature shall be recorded in the test report.
In addition, the test for deflection of shelves (6.1.4) and sustained load tests (6.2.1) except metal, stone
and glass shelves, shall be carried out at a relative humidity of 45 % to 55 %. If during a test the relative
humidity is outside this range, the maximum and/or minimum shall be recorded in the test report.
If a test cannot be carried out as specified (e.g. because a loading pad cannot be used for the application
of a force due to the design of a product), the test shall be carried out as closely as possible to that
specified.
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. Carry out measurements, if specified.
It is not necessary that all tests be carried out on the same unit, but all tests specified for a particular
component shall be carried out on the same component.
In Annex C, rationale for selected test methods is provided.
4.2 Application of forces
The test forces shall be applied sufficiently slowly to ensure that negligible dynamic force is applied.
Unless otherwise specified, each specified force shall be maintained for not less than 10 s and not more
than 15 s.
The test forces in durability tests shall be applied at a rate to ensure that excessive heating (3.11) does
not occur. Unless otherwise specified, each test force shall be maintained for (2 ± 1) s.
Forces shall be applied in a manner that ensures normal functioning of self-closing and damping
mechanisms. The forces can be replaced by masses. The relationship 10 N = 1 kg shall be used.
In Annex B, loads, forces and cycles are suggested to ensure that the test methods are of use where
no requirements document is available, or to assist in the development of one. See also Annex A for
guidance to develop requirements documents.
4.3 Tolerances
Unless otherwise stated, the following tolerances are applicable to the test equipment:
— forces: ± 5 % of the nominal force;
— velocities: ± 10 % of the nominal velocity;
— masses: ± 1 % of the nominal mass;
— dimensions: all dimensions less than 200 mm shall have an accuracy of ± 1 mm of the nominal
dimension; the other dimensions shall have an accuracy of ± 0,5 %; the dimension of the spherical
curvature of 300 mm radius on the loading pad (5.5) shall have an accuracy of ± 5 mm;
— angles: ± 2° of the nominal angles.
The accuracy for the positioning of loading pads shall be ± 5 mm.
Test forces, masses, dimensions, velocities and angles used to perform the test shall be targeted at the
nominal values specified and shall be subjected to the above tolerances.
NOTE For the purposes of uncertainty measurement, test results are not considered to be adversely affected
when the above tolerances are met.
4.4 Prevention of movement during test
If a free-standing unit (3.14) tends to overbalance during the tests specified in Clauses 6 and 7, load the
unit until this tendency stops, unless otherwise specified.
If a free-standing unit tends to slide during the tests specified in Clauses 6 and 7, with the exception of
6.4.2 and 6.4.3, the unit shall be restrained by stops (5.4).
4.5 Loading
Unless otherwise specified, for strength and durability tests, all storage components that are not
subject to testing shall be uniformly loaded according to Table 1.
Table 1 — Loads for strength and durability tests
Component Load
All horizontal storage areas, including shelves, bottoms, tops and flaps 0,65 kg/dm

a
Measured perpendicular to the plane of the filing pockets.
b
Maximum load 100 kg per unit.
5 Test equipment and apparatus
5.1 Unless otherwise specified, the tests can be applied by any suitable device, because results are
dependent only upon correctly applied forces and not on the apparatus.
The equipment shall not inhibit deformation of the unit/component, i.e. it shall be able to move so that
it can follow the deformation of the unit/component during testing, so that the loads are always applied
at the specified points and in the specified directions.
5.2 Floor surface, a rigid, horizontal and flat surface.
5.3 Wall surface, shall be rigid, vertical and flat.
5.4 Stops, devices to prevent the article from sliding but not tilting, not higher than 12 mm, except
in cases where the design of the unit necessitates the use of higher stops, in which case the lowest stop
that prevents the item from moving shall be used. For stability tests, the lowest height that prevents the
item from moving shall be used.
5.5 Loading pad, a rigid disc 100 mm in diameter, with a flat face and a 12 mm front edge blend
radius. Where space prevents the use of a 100 mm diameter loading pad, a 50 mm diameter loading pad
with similar properties can be used.
5.6 Apparatus for slam shut/open of extension elements, as given in Annex D.
5.7 Masses, shall be designed so that they do not reinforce the structure or re-distribute the stresses.
NOTE For the deflection of shelves (6.1.4), steel masses with a mass of 1 000 g and with a length of 85 mm, a
width of 50 mm, and a thickness of 30 mm are suitable.
5.8 Spherical objects, such as glass marbles with 10 mm to 15 mm diameter. They shall be loosely
packed in a flexible bag large enough to allow them to move in the bag during the test.
NOTE A bag that is approximately 50 % filled is considered loosely packed.
5.9 Loads for suspended filing pockets (3.24), shall be loaded with paper or an equivalent
alternative as shown in Figure 21.
5.10 Steel impact plates, 200 mm in length, with one surface faced with a 3 mm thick layer of rubber
with a hardness of (85 ± 10) IRHD according to ISO 48-5:2018. Other properties of steel impact plates
are as defined in Table 3.

5.11 Obstacles for castor durability tests, use two steel strips 50 mm wide and 2 mm high with the
edges having a radius of 2 mm, 500 mm apart and parallel on the floor surface and perpendicular to the
test direction.
5.12 TV Template, two templates constructed as frame or box as shown in Figure 2, with dimensions
as defined in Table 4, able to support a load acting through the centre of gravity of the TV template. The
weight of the unloaded template shall be (10 ± 0,2) kg.
The centre of gravity of the unloaded template shall be the geometric centre of the unloaded template.
When a load is added to the template, the variation of the position of the centre of gravity to that of the
unloaded template shall be restricted to 5 mm.
When testing, the template shall remain in its initial position.

6 Test procedures for non-movable parts
6.1 Shelves
6.1.1 General
For units with an indeterminate number of shelves, unless otherwise specified, divide the internal
height of the unit, in millimetres, by 200 and take the nearest integer. This number, minus one, shall
then be the number of shelves to be fitted.
The number of shelves (N) that shall be fitted is calculated by the following formula:
Nh= integer of /200 −1
()
where h is the internal height of the unit.
6.1.2 Shelf retention test — Horizontal outward force
This test is only applicable to shelves that are movable within the unit.
Apply the horizontal outward force specified to the middle of the front edge of the shelf.
6.1.3 Shelf retention test — Vertical downward force
This test is only applicable to shelves that are not fixed.
By means of a 50 mm diameter loading pad (5.5), apply the vertical downward force specified to a point
25 mm from the front edge of the shelf at the position most likely to cause failure.
6.1.4 Deflection of shelves
Testing of the deflection of shelves, which are not made of metal, glass or stone, shall be carried out in a
controlled humidity atmosphere (4.1).
Place the shelf on its supports in the unit.
The deflection of the shelf shall be measured at a point 10 mm from the front edge where the deflection
is greatest.
The deflection shall be measured to an accuracy of ± 0,1 mm with reference to a straight line parallel to
the front edge drawn between two adjacent supports.
Load the shelf uniformly (see Figure 3) with the load specified and apply for
— one hour for shelves made of metal, glass and stone, and
— one week for all other shelves.
At the same points as specified above, measure and record the deflection under load to an accuracy
of ± 0,1 mm and as a percentage of the distance between the supports.

6.1.5 Strength of shelf supports
Load the shelf uniformly with half the load specified for the deflection of shelf test (6.1.4), except at
220 mm from one support, where the impact plate (5.10) shall be tipped over 10 times over the support
(see Figure 4). The striking surface of the impact plate (5.10) shall be that faced with rubber. All
supports of the shelf shall be tested.
If the clear height (3.5) is less than 205 mm, the test is not carried out.
This test is not applicable to shelves, tops and bottoms that are fully supported by the structure of the
unit or have a length of less than 230 mm.
This test shall be carried out on all horizontal surface (e.g. shelves, tops and bottoms that can be used
as storage area).

6.2 Tops and bottoms
6.2.1 Sustained load test for tops and bottoms
This test is applicable to all tops and bottoms that are not completely supported by the floor during use.
The sustained load test shall be carried out in a humidity-controlled atmosphere (4.1).
The deflection of the top or bottom shall be measured where it is greatest.
The deflection shall be measured and recorded with reference to a straight line drawn between two
adjacent supports to an accuracy of ± 0,1 mm and as a percentage of the distance between the supports.
Load all components intended for storage purposes, with the specified load(s) in Table 1.
Load the top or bottom uniformly (see Figure 5) with the load specified and apply for
— one hour for tops and bottoms made of metal, glass and stone; review on enquiry, and
— one week for all other tops and bottoms.
Measure and record the deflection under load as specified above.

6.2.2 Static load test for tops and bottoms
This test is only applicable to tops that are ≤ 1 000 mm from the floor and to bottoms that are not
completely supported by the floor during use where the clear height (3.5) is 1 600 mm or more.
Load all components intended for storage purposes, with the specified load(s) in Table 1. Apply through
the loading pad (5.5) the specified vertical downward force 10 times at the worst-case position but not
less than 50 mm from the edges.
Record the loading point.
6.3 Clothes rails and supports
6.3.1 Strength of supports
When clothes rails are structurally interconnected, all the clothes rails shall be loaded.
The span of a clothes rail is the distance between consecutive supports.
Place the rail on its supports in the unit.
Load all components intended for storage purposes, with the specified load(s) in Table 1.
Each support shall be loaded consecutively. End supports shall be loaded with the specified load placed
as close as possible to the support. Intermediate supports shall be loaded with double the specified load
placed as close as possible to the support (see Figure 6).
The force shall be applied for 1 h.
