Application Summary AI generated
This standard specifies a test method for evaluating the DNA-damaging or repair-inducing potential of chemicals using bacterial cells, such as Escherichia coli or Bacillus subtilis. It is applied in the safety assessment of industrial chemicals, pharmaceuticals, and environmental pollutants to identify genotoxic substances that may cause mutations or cancer. The test is used by regulatory agencies and laboratories for chemical hazard classification and risk management in occupational and environmental health contexts.
