Resolution from IRG Working Group II Sub-group 4 'Stain in timber in service'

IRG/WP 2230

D J Dickinson

Sub-group 4 of IRG Working Group II has completed a series of studies of artificial weathering as an alternative to natural weathering in relation to testing the efficacy of chemicals in preventing blue stain in service. The Sub-group reports that within the limits of the equipments studied and described in its report Document No: IRG/WP/2215 the extent of blue stain varied little as a direct consequence of varying the artificial weathering system. The Sub-group considers that any or all of the methods based on the Atlas, Marr or Xenotest systems (as described in Table 4 of Document No: IRG/WP/2215) are suitable on technical grounds for inclusion in a specified methodology.
