Summary
The main objective of this study is to evaluate heat delamination characteristics of structural adhesives used for face bonding of cross-laminated timber, when subjecting both sides of CLT specimens to the small-scale flame test as required in the normative Annex A.2 of CSA O177 "Qualification Code for Manufacturers of Structural Glued-Laminated Timber" [3]. While not technically in accordance with the CSA O177 Annex A.2 methodology, this flame exposure allows for a direct comparison to previous work performed on glulam specimens [2]. The long-term objective is to determine which currently-accepted test method allows for a better evaluation of heat delamination characteristics of adhesives used in structural engineered wood products, based on their actual end-use applications (e.g. bending, compression, combined stress, etc.) and their inherent manufacturing characteristics (e.g. cross-plies, etc.)

Summary
The main objective of this study is to evaluate the heat release rate and fire growth contribution due to heat delamination characteristics of CLT manufactured with four types of adhesives used for face bonding, when exposed to a constant radiant heat flux. The evaluation is performed using the principles of ISO 5660-1 “Reaction-to-fire tests - Heat release, smoke production and mass loss rate – Part 1: Heat release rate (cone calorimeter method)”. The American version of this test method is ASTM E1354 « Standard Test Method for Heat and Visible Smoke Release Rates for Materials and Products Using an Oxygen Consumption Calorimeter ». The long-term objective is to determine which currently accepted test methods allow for the most suitable evaluation of heat delamination characteristics of adhesives used in structural engineered wood products, based on their actual end-use applications (e.g. bending, compression, combined stress, cross-plies, etc.).

Summary
The main objective of this preliminary study is to evaluate the heat release rate and fire growth contribution due to heat delamination characteristics of CLT manufactured with current certified ANSI/APA PRG-320 adhesives used for face bonding, when exposed to a constant radiant heat flux. The evaluation is performed using the principles of ISO 5660-1 “Reaction-to-fire tests - Heat release, smoke production and mass loss rate – Part 1: Heat release rate (cone calorimeter method)” [19]. The American version of this test method is ASTM E1354 « Standard Test Method for Heat and Visible Smoke Release Rates for Materials and Products Using an Oxygen Consumption Calorimeter » [20]. The long-term objective is to determine which currently accepted test methods allow for a better evaluation of heat delamination characteristics of adhesives used in structural engineered wood products, based on their actual end-use applications (e.g. bending, compression, combined stress, cross-plies, etc.)
