EVALUATION OF TWO METHODS USED IN ASSESSING WOOD FINISHING SYSTEMS AGAINST BLUE STAINING FUNGI

Abstract

Two testing methods, EN 152 and Chiptest, were evaluated to assess the effectiveness of wood finishing systems against blue-stain fungi. Method EN 152 was by exposing the treated samples to natural weathering, followed by laboratory fungal test. The Chiptest method was by laboratory fungal test without exposure to weathering. The assessments were done on the surface discolouration and blue-stain free zone. The study showed that EN 152 method was the more suitable for determining the effectiveness of the finishing system against blue-stain fungi.
