Reference 2

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
In accordance with point 1 of REACH Annex XI, it is considered justified to omit the testing for substances or mixtures which in contact with water emit flammable gases. Testing does not appear scientifically necessary as experience in use and experience of handling the substance indicates that it does not emit flammable gases in contact with water.

Reference 3

Endpoint:

pyrophoric solids

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
In accordance with point 1 of REACH Annex XI, it is considered justified to omit the testing for pyrophoric properties. Testing does not appear scientifically necessary as experience in use and experience of handling the substance indicates that it does not possess pyrophoric properties.

Description of key information

Flammability (solids)

Diphenyl carbonate is non-flammable, EU Method A.10, Bayer (2001b)

Key value for chemical safety assessment

Flammability:

non flammable

Additional information

Flammability (solids)

The endpoint is addressed with one key study (Bayer, 2001b). The study was awarded a reliability score of 2 in accordance with the criteria for assessing data quality as set forth by Klimisch et al. (1997).

The study was performed in accordance with the standardised guideline EU Method A.10 and the test material was determined to be not highly flammable.

Pyrophoric Properties and Substances which in Contact with Water Emit Flammable Gases

In accordance with point 1 of REACH Annex XI, it is considered justified to omit the testing for pyrophoric properties and testing for substances or mixtures which in contact with water emit flammable gases. Testing does not appear scientifically necessary as experience in use and experience of handling the substance indicates that it does not possess pyrophoric properties or emit flammable gases in contact with water.

Justification for classification or non-classification

In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No. 1272/2008, the substance does not require classification with respect to flammability.
