Furniture - Assessment of surface resistance to wet heat (ISO 4211-2:1993 modified)

This European Standard specifies a method of assessment of surface resistance to wet heat and relates to the rigid surfaces of all finished furniture, regardless of material, except for finishes on leather and fabrics which are excluded from this European Standard. The test is generally carried out on finished furniture but might be carried out on test panels of the same material, finished in an identical manner to the finished product and on a size sufficient to meet the requirements of the test.

Möbel - Bewertung der Beständigkeit von Oberflächen gegen feuchte Hitze (ISO 4211-2:1993 modifiziert)

Diese Europäische Norm legt ein Bewertungsverfahren für die Beständigkeit von Oberflächen gegen feuchte Hitze fest und gilt für starre Oberflächen von oberflächenbehandelten Möbeln unabhängig vom verwendeten Werkstoff, außer f für Oberflächen aus Leder und Textilien, die nicht unter diese Europäische Norm fallen. Die Prüfungen werden gewöhnlich am Möbel durchgeführt, können aber auch an Prüfkörpern durchgeführt werden, die aus dem gleichen Werkstoff mit identischer Oberflächenbehandlung wie das Möbel und groß genug sind, um den Anforderungen der Prüfung zu entsprechen.

Meubles - Evaluation de la résistance des surfaces a la chaleur humide (ISO 4211-2:1993 modifiée)

La présente norme européenne prescrit une méthode d'évaluation de la résistance des surfaces a la chaleur humide et porte sur les surfaces dures de tous les meubles finis sans distinction de matériau, a l'exception des finitions appliquées sur le cuir ou les tissus qui sont exclues de la présente norme européenne. L'essai est généralement réalisé sur des meubles finis, mais il pourrait etre effectué sur des panneaux d'essai de dimensions suffisantes pour satisfaire aux spécifications de l'essai, et du meme matériau et de finition identique au meuble fini.

ISO 4211=2:1993(E) Foreword ISO (the International Organization for Standardization) is a worldwide federation 0% national Standards bodies (ISO member bedies). The work of preparing international Standards is normally carried out through ISO technical committees. Esch member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. lnternational organizations, governmental and non-governmental, in liaison with ISO, also take patt in the work. 6SO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 421 l-2 was prepared by Technical Committee ISO/TC 136, Fumiture, Sub-Committee SC 1, Test methods. OS0 421% consists of the following Parts, under the general title Fumiture - Tests for surfaces: - Pari 2: Assessment of resistance to wet heat - Part 3: Assessment of resistance to dry heat - Part 4: Assessment of resistance to Impact - Part 5: Assessment o f resistance to scratching - Part 6: Assessment of resistance to abrasion - Part 7: Assessment of adhesion of finishes to Substrate NOTE 1 ISO 4211 :1979 was originally published as an independent International Standard, but is now regarded as part 1 of this series.

INTERNATIONAL STANQARD ISO 4211=2:1993(E) Furniture - Tests for surfaces - Part 2: Assessment of resistance to wet heat 1 Scope This part of ISO 4211 specifies a method of assess- ment of surface resistance to wet heat and relates to the hard surfaces of all finished furniture, regardless of material, except for finishes on leather and coated fabrics which are excluded from this part of ISO 4211. The test may be carried out on finished furniture but is generally carried out on test Panels of a size suffi- cient to meet the requirements of the test and of the same material and finished in an identical manner to the finished furniture. 2 Normative references The following Standards contain provisions which, through reference in this text, constitute provisions 0% this patt of ISO 4211. At the time of publication, the editions indicated were valid. All Standards are subject to revision, and Parties to agreements based on this part 0% ISO 4211 are encouraged to investigate the possibility of applying the most recent editions of the Standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.

After a specified period of time the block and damp cloth are removed. The test area is wiped dry and the test Panel left undis- turbed for at least 16 h. lt is then examined under specified lighting conditions for signs of darnage (dis- coloration, Change in lustre, blistering or other de- fects). The darnage is assessed by reference to a descriptive numerical rating Code. 4 Apparatus and materials 4.1 Thermometer, as specified in ISO 1770, ca- pable of insertion to the bottom of the centre bore of the heat Source (4.2) or other means of measuring the temperature of the heat Source to an accuracy of + 1 “C. - 4.2 Heat Source, block as shown in figure 1 manu- factured from aluminium alloy to ISO 209-1, Al Mg Si (alloy 6
