Overview

EN 12521:2023 - published by CEN - specifies minimum requirements for the safety, strength and durability of domestic tables intended for adult use, including tables incorporating glass. It defines test conditions and sequences, prescribes safety limits (e.g., finger entrapment and shear/compression points), and references additional test methods in Annex A (normative) and Annex B (informative). The standard replaces EN 12521:2015 and excludes office, educational, many non-domestic and outdoor tables, and trestle tables.

Key topics and technical requirements

• Scope & exclusions: Covers all types of domestic tables for adults; does not apply to office desks, trestle tables, or tables already covered by other European standards.
• Safety design: Edges and corners in contact with users must be rounded or chamfered; accessible edges free from burrs/sharp edges; movable parts must avoid inadvertent operation or injury.
• Finger entrapment & holes: No accessible holes between 7 mm and 12 mm (unless penetration depth < 10 mm); Annex A provides test methods for finger entrapment.
• Shear and compression points: Limits on gaps created by moving parts:
  • Powered mechanisms: no gap < 25 mm and > 8 mm during movement that could cause injury (tested per Annex A).
  • During normal use: no gap < 18 mm and > 8 mm (tested per Annex A).
• Glass safety: Glass is classified as safety glass if it meets EN 12150-1 fragmentation criteria (or equivalent fragmentation mode). Table 2 vertical impact test applies to glass table tops.
• Stability: Specific stability tests for delicate tables (max surface area 0.30 m²) and other tables; delicate-table criteria include height ≥ 600 mm and weight > 10 kg.
• Strength & durability: Durability requirements cover fixed, height-adjustable, cantilever/pedestal tables and those with castors; tests reference EN 1730:2012. Test forces may be expressed as masses (10 N = 1 kg).
• Annexes: Annex A (normative) - finger entrapment and shear/compression test methods; Annex B (informative) - tabletop deflection test; Annex C (informative) - rationale.

Applications and users

• Manufacturers & designers: Use EN 12521:2023 to design compliant domestic tables and select appropriate materials (including glass).
• Testing laboratories: Apply the normative test methods (Annex A/B) and EN 1730 referenced procedures for conformity testing.
• Retailers, importers & compliance officers: Use requirements to verify product safety and prepare technical documentation for market access.
• Procurement & standards writers: Reference the standard for safety specifications in tenders and national adoption.

3.5
ancillary surface

4 Test conditions and test sequence
The tests shall be carried out in the order in which they are listed in Table 2.
The test conditions shall be as contained in EN 1730:2012, 4.1.
The test forces may be replaced by masses. The relationship 10 N = 1 kg shall be used.
5 Safety requirements
5.1 General
The table shall be so designed as to minimize the risk of injury to the user.
All parts of the table with which the user comes into contact during intended use when the table is
positioned in its intended configuration of use shall be so designed that physical injury and damage are
avoided.
These requirements are met when:
a) the edges and corners of table tops which are directly in contact with the user are rounded or
chamfered;
b) all other edges and corners accessible during intended use are free from burrs and/or sharp edges.
Movable and adjustable parts shall be designed so that injuries and inadvertent operation are avoided.
It shall not be possible for any load bearing part of the table to come loose unintentionally.
All parts that are lubricated to assist sliding shall be designed to protect users from lubricant stains when
in normal use.
5.2 Holes in tubular or rigid components
There shall be no holes in tubular components or holes in rigid components in accessible parts between
7 mm and 12 mm, unless the depth of penetration is less than 10 mm. This requirement is fulfilled if there
is no hazard present when tested in accordance with A.1.
5.3 Shear and compression points
5.3.1 General
The requirements contained within 5.3.2, 5.3.3 and 5.3.4 do not apply to electrically operated furniture.
NOTE The requirements for electrically operated furniture will be provided in EN 17684, which is under
preparation.
5.3.2 Shear and compression points when setting up and folding
Unless 5.3.3 or 5.3.4 are applicable, shear and compression points that are created only during setting up
and folding are acceptable, because the user can be assumed to be in control of his/her movements and
to be able to cease applying the force immediately upon experiencing pain.
The edges of parts moving relative to each other and creating shear and compression points shall be as
specified in 5.1.
5.3.3 Shear and compression points under influence of powered mechanisms
With the exception of operation of doors, flaps and extension elements, there shall be no areas where the
distance between two accessible parts moving relative to each other can be less than 25 mm, and more
than 8 mm in any position during movement that could present a risk of injury to the user, created by
parts of the furniture operated by powered mechanisms, e.g. mechanical springs and gas lifts.
This requirement is fulfilled if there is no hazard present when tested in accordance with A.2.2.
5.3.4 Shear and compression points during use
With the exception of operation of doors, flaps and extension elements, there shall be no areas where the
distance between two accessible parts moving relative to each other can be less than 18 mm, and more
than 8 mm in any position that could present a risk of injury to the user, created by loads applied during
normal use.
The loads used for durability tests within Table 2 are considered representative of normal use.
This requirement is fulfilled if there is no hazard present when tested in accordance with A.2.3.
5.4 Glass
5.4.1 Safety glass
For glass to be considered to be ‘safety glass’ when tested in accordance with Table 2, Test 8 – Vertical
impact test for glass table tops, either:
a) the manufacturer, importer or retailer, provides verification that the glass fulfils the requirements in
EN 12150-1:2
