Abstract [en]

Nordtest and SP Swedish National Testing and Research Institute (SP) have financed a study to draft a common Nordic test method to classify wood adhesives for structural purposes according to strength properties after fire exposure. The study has been planned and carried out in cooperation between SP and Norwegian Institute of Wood Technology (NTI) with participation of Otto Graf Institute in Germany (FMPA). Glulam beams produced with six different adhesives have been exposed to fire. Temperature distribution during the fire exposure test, weight loss and charring rate have been determined. Shear strength of glulines and wood have been determined and delamination tests have been carried out on samples exposed to fire and samples not exposed to fire. Short term shear strength and creep rupture tests at elevated temperature have been carried out on samples with wood adhesives used in the test. Preliminary calculations of temperature distributions during fire in wooden members protected against direct fire exposure by gypsum board have been made. The results of the study on beams not protected by gypsum indicate that a wood adhesive that has shown favourable results in a creep rupture test at elevated temperature (80 °C) also will perform well during and after direct fire exposure. A static load test at elevated temperature can be used as an efficient and cheap method as an alternative to fire exposure tests of glued products for structural use. The results of the preliminary calculations on temperature distributions during fire exposure of gypsum protected smaller wood members indicate that under certain circumstances, the temperature can reach and stay at temperatures above 120 °C for a longer period of time. An additional test at higher temperature could be needed for adhesives intended for such structures.
