Corrosiveniss is an undesirable characteristic in awood preservative, because it results indamage to the metal of the treating equipment and to the metal fittings and fastenings, as may be applied to the wood in service. The ohviously corrosive chemicals find little or no use as wood preservatiyes. Howeever, it is necessary to consider the possible deterioration of metals, such as nails, bolts and the like. An investigation to determin the corrosiye action on galvenized-iron wire caused by wood preservatives was done by five methods including the similar method described in Japanese indastrial standard A 9304. The results obtaained were as follows: 1) It was shown that the corrosive action by oil-berne or emulsifiable concentrates was not serious. On the other hand, water treatment has been shown to have greater corrosive action on test wire. 2) The greater corrotion to the galvanized-iron wire was observed when the wire was steeped in the preservative solution to the extent of about half of the wire length. 3) The oil borne type is found less corrosive to galvanized-iron wire than emulsifiable concbntrate. 4) The white rust grown on the galvanized-iron wire was tried to remove by treating with 10 parsent of diammonium citrate aquabus solution. In this case, treating conditions showd a remarkable influense to the loss in weight of the test wire.
