Adhesives - Wood adhesives for non-structural applications - Determination of tensile shear strength of lap joints
This European Standard specifies tests for adhesives for wood and derived timber products for the assessment of their resistance to hot and cold water. It can be used for the assessment of the strength of bonds with a thin bond-line. It does not apply to adhesives for structural use or to the manufacture of particleboards, fibreboards and plywood. It does not replace tests on finished products.
Klebstoffe - Holzklebstoffe für nicht tragende Anwendungen - Bestimmung der Klebfestigkeit von Längsklebungen im Zugversuch
Diese Europäische Norm legt Prüfungen für Klebstoffe für Holz und Holzprodukte im Hinblick auf ihre Beständigkeit gegen warmes und kaltes Wasser fest. Sie kann zur Beurteilung der Klebfestigkeit von Klebungen mit dünner Klebstofffuge verwendet werden. Sie gilt nicht für Klebstoffe für tragende Bauteile oder zur Herstellung von Spanplatten, Faserplatten und Sperrholz. Sie ersetzt keine Prüfungen für Fertigprodukte.
Adhésifs - Colles pour bois à usages non structuraux - Détermination de la résistance au cisaillement en traction des joints à recouvrement
La présente Norme européenne spécifie une méthode d'essai applicable aux colles pour bois et pour matériaux dérivés du bois, permettant d'évaluer leur résistance à l'eau chaude et à l’eau froide. Elle peut être utilisée pour évaluer la résistance à la rupture des joints présentant un joint de colle mince. Elle ne s'applique pas aux adhésifs destinés à des usages structuraux ni à la fabrication des panneaux de particules, des panneaux de fibres et des contreplaqués, et ne remplace pas les essais sur des produits finis.
Lepila - Lepila za les za nekonstrukcijsko uporabo - Ugotavljanje natezno-strižne trdnosti spojev s preklopom
Ta evropski standard določa preskuse za lepila za les in lesne proizvode za oceno njihove odpornosti na vročo ali mrzlo vodo. Uporablja se lahko za oceno trdnosti vezav s tanko vezno linijo. Ne uporablja se za lepila za uporabo pri konstrukcijah ali proizvodnjo ivernih plošč, vlaknenih plošč in vezanih plošč. Ne nadomešča preskusov končnih proizvodov.

EN 205:2016 (E) 3 European foreword This document (EN 205:2016) has been prepared by Technical Committee CEN/TC 193 “Adhesives”, the secretariat of which is held by AENOR. 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 February 2017, and conflicting national standards shall be withdrawn at the latest by February 2017. 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. This document supersedes EN 205:2003. Compared to EN 205:2003 the following modifications have been made: a) assessment of the strength based on thick bond lines deleted; b) processing conditions for adhesive application specified in 6.1 if no manufacturer's instructions are available; c) number of test pieces modified in 6.3; d) test results of all 20 test pieces to be given in the test report. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 205:2016 (E) 4 Introduction European Standards giving a common classification with respect to durability classes for wood adhesives will allow considerable improvement in consumer protection in any future product liability system with regard to properties guaranteed by the adhesive manufacturer. The methods described in this standard are suitable for the following and other applications: — assessing the usability and quality of adhesives for wood and derived timber products; — classifying these adhesives into the durability classes D1 to D4 of EN 204 (thermoplastic adhesives) and C1 to C4 of EN 12765 (thermosetting adhesives); — assessing effects on the bond strength resulting from the bonding conditions chosen, the various conditioning sequences and the treatment of the test pieces before and after bonding. SAFETY STATEMENT — Persons using this document should be familiar with the normal laboratory practice, if applicable. This document does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any regulatory conditions. ENVIRONMENTAL STATEMENT — It is understood that some of the material permitted in this standard may have negative environmental impact. As technological advantages lead to acceptable alternatives for these materials, they will be eliminated from this standard to the extent possible. At the end of the test, it is essential that the user of the standard take care to carry out an appropriate disposal of the wastes, according to local regulation SIST EN 205:2016
