Each member body interested in a subject for which a technical committee has been 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. International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 2. The main task of technical committees is to prepare International Standards. 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. 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.

This International Standard focuses on bond line performance and is directed principally at the evaluation of wood adhesives. When used in this manner, the tests and assessments are made against standardized wood preservative and fire-retardant treated wood. It is expected that product standards (e.g. for glulam, laminated ofqualificationprocedures. The matter of high temperature performance has been controversial in that various national standards have requirements for: strength testing at 220 °C or higher, creep testing at 180 °C or higher, creep testing at 70 °C or higher, placed in this part of isO 20152. Manufacturers of adhesive should familiarize themselves with local building regulations to determine if the“additional" requirements are necessary. Users of this International Standard are reminded that local building regulations are a matter for determination by iv ISO 2011 -All rights reserved ISO 20152-2:2011(E) INTERNATIONALSTANDARD TimberstructuresBondperformanceofadhesives Part 2: Additional requirements 1 Scope This International Standard specifies the performance requirements of wood bond lines in prefabricated structural timber components. 2 Normative references The following referenced documents are indispensable for the application of this document.
