European foreword
This document (EN 15187:2024) has been prepared by Technical Committee CEN/TC 207 “Furniture”,
the secretariat of which is held by UNI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by January 2025, and conflicting national standards shall
be withdrawn at the latest by January 2025.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.

— added new Table 3 “Correlation between irradiation time and total irradiation amount at different
intensity”
— new sub clauses: “Specimen holders”, “Deionized or distilled water”, “Cleansing solution”, “Cleansing
agent” added to Clause 5;

1 Scope
This document specifies a method for the assessment of the effects of light in indoor conditions, by
exposure to artificial radiation and applies to rigid surfaces of all finished products regardless of material.
It does not apply to finishes on leather and fabrics.
The test is intended to be carried out on a part of the finished furniture, but can be carried out on test
panels of the same material, finished in an identical manner to the finished product, and of a size sufficient
to meet the requirements of the test.
This document describes the most important parameters, such as the colour change when a surface is
exposed and specifies the conditions to be used in the exposure apparatus.
The light resistance of a surface can be assessed by using two apparatus as specified in Clause 4, one as a
reference test method, and the other for in-company testing.

3.1
test panel
panel including the test surface (see 3.2)
Note 1 to entry: It can be cut from a finished item of furniture or it can be a separate panel produced in the same
manner as the finished item of furniture.
3.2
test surface
part of the test panel including an exposed section as well as the control sections

As amended by EN ISO 4892-2:2013/A1:2021.
Note 1 to entry: See Figure 1 and Figure 2.
4 Principle
4.1 General
Accelerated exposure to light of furniture surfaces to filtered xenon-arc radiation is carried out in order
to assess the change of contrast and colour. The surface is assessed by comparing the exposed section
with the masked control section or with the separated control section (see Clause 8) from the same test
surface.
4.2 Choice of methods
The apparatus specified in 5.1 shall be used as a reference method in cases where the influence of
humidity cannot be excluded.
The apparatus specified in 5.2 can be used for in-company testing in cases where the influence of
humidity can be excluded.
5 Apparatus and materials
5.1 Apparatus with humidity control
A test device as specified in EN ISO 4892-1 and EN ISO 4892-2:2013 with xenon lamp using window
glass filters according to method B in EN ISO 4892-2:2013 , and test parameters, as specified in Table 1.
