NUMBER OF REPLICATIONS: 3 per concentration - Evaluation criteria:
- A test item is considered mutagenic if:
-A dose-related increase in the number of revertants occur and/or:
-A reproducible biologically relevant positive response for at least one of the test points occurs in at least one strain with or withour metabolic activation. - Statistics:
- The mutation factor is calculated by dividing the mean value of the revertant counts through the mean values of the solvent control.
