    Description

    Southern pine plywood is substantially all being manufactured with phenolic glue for exterior use. Because panels must not delaminate in service, a reliable predictor of glueline durability is required. Drawing on the experience of the Douglas-fir plywood industry, southern manufacutrers have adopted as a predictor the percentage of wood failure(% WF) observed in randomly selected and thoroughly wetted shear specimens. A high % WF is accepted in the industry as evidence that the bond will be durable (7, 6).
