Materials and methods

Test guideline

Qualifier:

according to guideline

Guideline:

other: JISA-9201, 9302, 9301 (Standard Japanese procedure for testing efficacy of wood preservative)

Deviations:

not specified

Principles of method if other than guideline:

Method is used to test efficacy of chemicals used as wood preservatives against specified test fungi. Standardized wood blocks, both weathered and unweathered, are treated (pressure impregnation) with a range of concentrations of the test chemical and incubated with the decay fungi for 90 days. Weight loss of the test block is used to assess the efficacy of the chemical preservative.

GLP compliance:

Results and discussion

Any other information on results incl. tables

The concentrations of 2,4,6-TBP reported (e.g. efficacy against decay fungi at concentrations down to 0.5% dilution, which is pressure impregnated into the wood) are applicable only to wood preservation.

Applicant's summary and conclusion

Conclusions:

Report consists of very short summary and data tables, with standard methods attached. Appears to have followed the attached standard methods (Japanese methods for testing efficacy of wood preservatives, JISA-9201, 9302, and 9301). No analytical details provided. The concentrations of 2,4,6-TBP reported (e.g. efficacy against decay fungi at concentrations down to 0.5% dilution, which is pressure impregnated into the wood) are applicable only to wood preservation. However, it can be concluded from study that 2,4,6-TBP is toxic to the tested decay fungi at particular concentrations.
