Endpoint:
substances / mixtures which in contact with water emit flammable gases
Type of information:
other: statement
Adequacy of study:
key study
Study period:
25 August 2009 – 12 October 2009
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: The EU method was followed. Based on the molecular structure of the test substance a statement rather than a full study was considered sufficient to cover this endpoint.
Qualifier:
according to
Guideline:
EU Method A.12 (Flammability (Contact with Water))
Deviations:
not applicable
GLP compliance:
yes (incl. certificate)

The structure of the test substance does not contain groups that might lead to the evolution of a dangerous amount of flammable gas when coming into contact with water or damp air. No metals, transition metals, boron or silicon are present. Moreover, the test substance is known to be water-soluble. The impurities were not taken into account but it is not to be expected that these have any influence.It is not to be expected that an interaction between the different components occurs.

Interpretation of results:
other: not highly flammable
Conclusions:
HEXAHYDRO-1,3,5-TRIMETHYL-S-TRIAZINE is not highly flammable in contact with water or damp air.
Endpoint:
flammability
Type of information:
other: statement
Adequacy of study:
key study
Study period:
25 August 2009 – 12 October 2009
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
The EU method was followed. Based on the molecular structure of the test substance a statement rather than a full study was considered sufficient to cover this endpoint.
Qualifier:
according to
Guideline:
EU Method A.13 (Pyrophoric Properties of Solids and Liquids)
Deviations:
not applicable
GLP compliance:
yes (incl. certificate)

The molecular structure of the test substance does not contain any chemical groups that might lead to spontaneous ignition a short time after coming into contact with air. The impurities were not taken into account but it is not to be expected that these have any influence.It is not to be expected that an interaction between the different components occurs. Furthermore, experience in handling (see section 4.12) shows that the test substance does not ignite spontaneously after coming in contact with air at room temperature.

Interpretation of results:
other: not pyrophoric
Conclusions:
HEXAHYDRO-1,3,5-TRIMETHYL-S-TRIAZINE is not pyrophoric.

Description of key information

Flammability in Contact with Water = Not flammable, EC A.12, Baltussen (2010)

Pyrophoricity = Not pyrophoric, EC A.13, Baltussen (2010)

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

Two key studies were submitted for this endpoint. In studies conducted in accordance with EC Method A.12 and EC Method A.13, the substance was determined not to be flammable or pyrophoric (Baltussen, 2010).

Justification for classification or non-classification

An assessment of flammability on contact with water and pyrophoricity both produced negative results in the presented studies. The test item is therefore considered to be non-flammable and no classification is required under Regulation (EC) No 1272/2008.
