Foreword
This Technical Report (CEN/TR 581-4:2005) has been prepared by Technical Committee CEN/TC 207
“Furniture”, the secretariat of which is held by UNI.
Introduction
This standard is part of a series of standards dealing with various aspects of outdoor furniture. Preceding
parts of that series are dealing exclusively with safety. This part covers the aspects of durability, i.e. the ability
of outdoor furniture to withstand long-term mechanical damage and damage arising from the weather. As far
as the weather has an impact not only to the appearance (surface finish) but also to safety features, there is
sufficient evidence to deem that the interior load bearing structure of plastic outdoor furniture remains
sufficiently strong as long as the outer surface shows no significant signs of cracks caused by UV- radiation.
An undamaged surface is additionally an important durability characteristic in itself. Due to different materials
and surface treatments the ability of outdoor furniture to withstand damages caused by natural weather differs.
Therefore this standard provides a range of "weatherability" levels in order to classify the surface finish
regarding its durability to weather. That characteristic is named in the following text as "weatherability". A
standardised information label is foreseen in that context in order to inform the consumer about structural
durability, recommended application and the degree of "weatherability". The level to be classified is voluntary,
it aims to allow informed choice for the customer when buying outdoor furniture.
Levels of structural durability of an outdoor furniture are set by opening the three areas applications
respectively levels of strength as set by ENV 581-2 and EN 581-3 and making them a tool to declare
enhanced durability. To meet the higher strength requirements of a following application means to prolong
durability. The durability level to be chosen is voluntary and thus matter of declaration. The three applications:
CAMPING / DOMESTIC / CONTRACT include consequently three levels of durability. Therefore the group of
experts felt, that the three levels of strength respectively fields of application constitute automatically three
levels of structural durability.
The issue of resistance to UV-radiation, i.e. of long-term strength and safety, is taken into account in this part
of the standard (5.2) by deriving structural strength and safety from an undamaged surface after artificial
weathering.
"Weatherability" for the purpose of this standard is related to the ability of outdoor furniture to maintain its
original aesthetic look respectively appearance for a prolonged time.
In accordance with usual practice in the outdoor furniture market three performance levels for "weatherability"
of surface finish were specified in order to make the mentioned ability assessable. An additional "zero level"
indicates the case where no "weatherability" in terms of unchanged appearance is claimed. In that case the
influences of weather may lead to a rapid change in the surface finish of the outdoor furniture. Subjectively
and individually that need is not to be considered as a deficiency. The declaration of the "zero level" fact was
felt to be a question of fair practice and the avoidance of misunderstandings between supplier and customer
that might otherwise cause complaints. Additionally the informative label together with the instructions for use
give advice how through care and maintenance the durability of the outdoor furniture can be prolonged.
Outdoor furniture made from wood which is inherently weather proof (as e.g. teak wood) and where the
change in appearance due to weather is rather seen as a typical and even desired "patina" than a deficiency
are intentionally exempt from the weather testing. Consumer information in this case means: Declaration of
wood within the product information label (see Clause 8)
Due to the fact that natural weather does not consider the diversity of materials from which the piece of
furniture might be made, the "weatherability" test follows a "general approach" submitting any outdoor
furniture to the same conditions of exposure. As the existing test facilities for artificial weathering do not
provide the possibility to check an entire piece of furniture, the group follows the traditional way to test
specimens. For the need to get test results in an adequate time a natural weathering test was not specified.
Furthermore the document does not include requirements for chemical or mechanical surface stresses as they
may arise from food stuff, cleaning agents, scratching, abrasion, smouldering cigarettes etc.
