Applicant's summary and conclusion

Conclusions:
The pH determination of test item N-tert-butylacrylamide (CAS No 107-58-4) was done following OECD guideline 122. pH of 1% w/v dispersion was measured with the help of pH meter and it was observed to be 6.52 at 26.2 °C
Executive summary:

The pH determination of test item N-tert-butylacrylamide (CAS No. 107-58-4 ) was done as per the test guideline OECD 122. The mean pH of the test dispersionwas determined with the help of digital pH meter. The mean pH was determine to be 6.52 at 26.2 °C.
