- Acceptance criteria
Generally, the experiment is to be considered valid if the following criteria are met:
• The number of revertant colonies in the negative controls was within the normal range of the historical control data for each tester strain.
• The sterility controls revealed no indication of bacterial contamination.
• The positive control articles both with and without S-9 mix induced a significant increase in the number of revertant colonies within the range of the historical control data.
• The titer of viable bacteria was >10E9/ml.
Evaluation criteria
The test chemical is considered positive in this assay if the following criteria are met:
• A dose-related and reproducible increase in the number of revertant colonies, i.e, about doubling of the spontaneous mutation rate in at least one tester strain either without S-9 mix or after adding a metabolizing system.
A test substance is generally considered nonmutagenic in this test if:
• The number of revertants for all tester strains were within the historical negative control range under all experimental conditions in two experiments carried out independently of each other.

Applicant's summary and conclusion
- Conclusions:
- Under the conditions of the study, the test substance was therefore not mutagenic in the Salmonella typhimurium/ Escherichia coli reverse mutation assay.
- Executive summary:
A study was conducted to determine the mutagenic potential of the test substance according to OECD Guideline 471 and EU Method B13/B14, in compliance with GLP. The tested strains were Salmonella typhimurium TA 1535, TA 100, TA 1537 and TA 98, and Escherichia coli strain WP2 uvrA. A standard plate and a pre-incubation test were run, both in dose range of 36 to 9000 µg test substance / plate, with and without Arochlor-induced rat liver S9 mix. No precipitation of the test substance and no bacterio-toxic effect were found. An increase in the number of his+ or trp+ revertants was not observed in either of the assays, either with or without S9 mix. Under the conditions of the study, the test substance was therefore not mutagenic in the Salmonella typhimurium/ Escherichia coli reverse mutation assay (Engelhardt, 2000).
