Applicant's summary and conclusion
- Validity criteria fulfilled:
- not specified
- Conclusions:
- A validation of the results is not possible, as neither validation crieria had been documented, nor the absolute values of the gas production activities had been recorded within all the laboratory manuscripts of the fermentation tube tests. No classification can be made on the base of this result.
- Executive summary:
Product has not to be classified.
