Applicant's summary and conclusion

Interpretation of results:
Category 1 (irreversible effects on the eye) based on GHS criteria
Conclusions:
The substance needs to be considered as severe eye irritant, cat. 1.
Executive summary:

Substance is listed in the consolidated version of EU Regulation 1272/2008 as corrosive, leading to a classification as serious eye damage (Cat. 1).  The substance is highly reactive and hydrolyzes in contact with water or body fluids to the corresponding pyromellitic acid; measured ph-value of hydrolyzed material in water is 2. In literature, the substance is reported to be severly irritant to eyes in a standard Draize test, therefore it was decided to take over this classification and to conduct no further studies.
