Investigation of the fixation in wood of chromated zinc chloride and copperised chromated zinc chloride preservatives

IRG/WP 372

V N Sozonova, D A Belenkov

A biological method of evaluating the extent to which CZC and CCZC preparations are retained in wood in terms of the potential protection which they afford against destruction by Merulius lacrymans (dry rot) is given. CCZC is recommended for protection of wood under moderate leaching conditions, while the use of CZC under such conditions is not recommended.
