Endpoint:
substances / mixtures which in contact with water emit flammable gases
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING


The following statement has been reported by an expert:

A test substance is considered highly flammable when it ignites spontaneously in contact with water, or evolves a flammable gas at a minimum rate of ≥ 1 litre/kg of the substance per hour.
 
The molecular structures of the main constituents in the test substance do not contain groups that might lead to ignition in contact with water and/or to the evolution of a flammable gas. Moreover the test substance was dissolved in water during the determination of the water solubility. It demonstrated that the test substance does not ignite spontaneously in contact with water.
 
In conclusion, PEMP product is considered ‘not highly flammable’ in contact with water.

Qualifier:
according to
Guideline:
other: UN ST/SG/AC.10/11/Rev.5: Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Appendix 6 "Screening procedures" (2009)
Deviations:
no
Interpretation of results:
not classified based on GHS criteria
Conclusions:
The substance PEMP product is considered ‘not highly flammable’ in contact with water.
Endpoint:
pyrophoric liquids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING

The following statement has been reported by an expert:

A test substance is considered pyrophoric when it ignites within five minutes of coming in contact with air.

The molecular structures of the main constituents in the test substance do not contain groups that might lead to ignition in contact with air. Moreover the test substance was handled under normal laboratory conditions during this project. It demonstrated that the test substance does not ignite in contact with air.
 
In conclusion, PEMP product has no pyrophoric properties.

Description of key information

No pyrophoric properties and 'not highly flammable in contact with water' (based on experience in handling and on structural features: UN-MTC Appendix 6).

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Flash point: > 200°C

Auto-ignition temp.: 345°C

Justification for classification or non-classification

-Because the flash point is > 60°C, no classification is required for the CLP hazard 'Flammable liquid'.

-No classification is required for the CLP hazard 'Pyrophoric liquids' or 'Substances which in contact with water emits flammable gases'.

-Because of its high auto-ignition temperature and because the substance is a liquid, no classification is required for the CLP hazard 'self-heating' .
