Timber structures - Joints made with mechanical fasteners - General principles for the determination of strength and deformation characteristics (ISO 6891:1983)

Applies to joints made with mechanical fasteners used in statically loaded timber structures. Covers the conditioning of test specimens and explains the apparatus to be used for measuring the geometry of the test specimens, their moisture content and other characteristics. Details the loading procedure and specifies the details to be included in the test report.

Structures en bois - Assemblages réalisés avec des éléments mécaniques de fixation - Principes généraux pour la détermination des caractéristiques de résistance et de déformation (ISO 6891:1983)

La présente Norme internationale spécifie des principes généraux pour la détermination des caractéristiques de résistance et de déformation (glissement) des assemblages réalisés avec des éléments mécaniques de fixation.
La présente Norme internationale est applicable aux assemblages réalisés avec des éléments mécaniques de fixation, utilisés pour les structures en bois soumises à des charges statiques. Des modes opératoires détaillés, appropriés aux assemblages réalisés avec des éléments de fixation spécifiques, seront fournis dans des Normes internationales particulières. Le principe de ces méthodes peut aussi être appliqué à l'essai d'autres sortes d'assemblages. Il est reconnu que pour certains types particuliers d'assemblages non couverts par des Normes internationales, des modifications du mode opératoire d'essai peuvent être nécessaires.

Foreword ISO (the International Organization for Standardization) is a worldwide federation of national Standards bodies (ISO member bodies). The work of developing International Standards is carried out through ISO technical committees. Every member body interested in a subject for which a technical committee has been authorized 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. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISO Council. International Standard ISO 6891 was developed by Technical Committee ISO/TC 165, 77mber structures, and was circulated to the member bodies in January 4982. lt has been approved by the member bodies of the following countries : Australia Egypt, Arab Rep. of Austria France Belgium Germany, F. R. China India Czechoslova kia Ireland Denmark New Zealand Norway Portugal Romania South Africa, Rep. of Sweden United Kingdom The member body technical grounds of the following country expressed disapproval of the document on Canada 0 International Organization for Standardization, 1983 Printed in Switzerland SIST EN 26891:1997

INTERNATIONAL STANDARD ISO 68914983 (E) Timber structures - Joints made with mechanical fasteners - General principles for the determination of strength and deformation characteristics 0 Introduction Developments in the field of load-bearing timber structures re- quire that joints made with mechanical fasteners be tested to obtain information about their strength and deformation (Slip) characteristics. This International Standard lays down general principles which should be followed in Order to achieve comparability of results from investigations carried out in different laboratories. Stan- dard rules for the determination of characteristic strengths for particular types of mechanical fasteners will be given in separate International Standards. This International Standard is based on Joint Recommenda- tions from Working commission W18, Timber Structures, of CIB1) and Co mmittee 3TT, Timber Testing, of RlLEM*), who will also prepare the basis for the above-mentioned supplemen- tary International Standards. 1 Scope This International Standard lays down general principles for the determination of the strength and deformation (Slip) charac- teristics of joints made with mechanical fasteners. 2 Field of application This International Standard is applicable to joints made with mechanical fasteners used in statically loaded timber struc- tures. Detailed procedures appropriate to joints made with specific fasteners will be given in separate International Standards. The principles tan also be used for the testing of other joints. lt is recognized that for some special types of joints not covered by International Standards, modification of the test procedure may be necessary. 3 Reference ISO 554, Standard atmospheres for conditioning and/or testing - Specifica Gons. 1) International Council for Building Research, Studies and Documentation. 2) International Union of Testing and Research Laboratories for Materials and Structures.

The conditioning should be conducted in such a way that the test conditions correspond in a realistic manner to the condi- tions in joints in structures as regards the influence of t
