Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 4211-5:2021(E)
Furniture — Tests for surface finishes —
Part 5:
Assessment of resistance to abrasion
1 Scope

This document specifies a method for the assessment of the abrasion resistance of surfaces with foils,

laminates, melamine faced boards, pigmented and transparent lacquers.

The test is intended to be carried out on an unused 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.

4 Principle

The test simulates the ability of the furniture surface under test, to resist abrasive wear-through.

Abrasion is achieved by rotating a specimen in contact with a pair of loaded cylindrical wheels covered

with abrasive paper. The wheels are positioned so that their cylindrical faces are equidistant from the

specimen's axis of rotation but not tangential to it. As they are turned by the rotating specimen, they

abrade an annular track on the specimen's surface. The number of revolutions of the specimen required

to cause one defined degree of abrasion, is used as measurement of resistance to surface wear.

5 Apparatus and materials
5.1  Cleaning cloth. White soft absorbent cloth.

5.2 Calibration plates, which shall be Taber S-34 or equivalent, having a thickness of (0,8 ± 0,1) mm

and a Brinell hardness of (48 ± 2) when tested in accordance with ISO 6506-1, except that the ball

diameter shall be 5 mm and the load 360 N.

5.3 Abrasion paper strips, which shall be Taber S-42 or equivalent, of width (12,7 ± 0,1) mm and

length about 160 mm, according to the following specifications:
2 2
a) paper of grammage from 70 g/m to 100 g/m ;

b) open coated 180 grit powdered aluminium oxide (Al O ) having a particle size such that it will pass

2 3

through a sieve of aperture 100 µm and remain on a sieve having an aperture of 63 µm;

c) adhesive backing.

5.4 Test apparatus, which shall be as specified in ISO 9352 with following deviations :

a) the hardness of wheels' rubber layer shall be between 60 Shore A and 70 Shore A, when measured

in the middle of the contact surface; make 4 measurements and calculate the average value;

The laboratories should measure the hardness at least once every 12 months. Checking of rubber wheels

geometry shall be performed. If any deformation is observed the rubber wheel should be rejected.

b) weight of loading: every wheel shall apply a force (5,4 ± 0,2) N on the sample;

c) vacuum system: the suction nozzle should be as close to the surface as possible without rubbing it.

The vacuum system shall remove practically all the dust;

d) the distance between the middle axis of the sample holder and the wheels should be calibrated

according to Annex A;
e) the table rotary speed shall be (60 ± 2) r/min.

5.7  Diffuse light source, providing evenly diffused light giving an illumination on the test surface of

(1 200 ± 400) lx. This may either be diffused daylight or be diffused artificial daylight.

The daylight should be unaffected by surrounding trees, buildings, etc. When artificial light is used,

it is recommended that it should have a correlated colour temperature of (6 500 + 50) K and a colour

rendering index (R ) greater than 92, by using a colour matching booth in accordance with ISO 3668.

6 Preparation and conditioning

Conditioning of test surface shall begin at least one week before testing and shall be carried out in air at

a temperature of (23 ± 2) °C and relative humidity of (50 ± 5) %.

NOTE The final curing of some coatings, such as waterborne coatings, can require a longer conditioning

time.
The conditioning time shall be stated in the test report.
