Endpoint:

flammable solids

Type of information:

read-across from supporting substance (structural analogue or surrogate)

Adequacy of study:

key study

Reason / purpose for cross-reference:

read-across source

- The flame of the gas burner did ignite the test substance pile. The test substance melted, burned with a yellow flame and turned into a light brown to black residue. Grey smoke was observed. After removal of the ignition source, the flame extinguished after 2 seconds and no propagation of combustion was observed.

- As no propagation of combustion of the test substance along 200 mm length of the pile within 4 minutes was observed, performance of the burning rate test is not required in accordance with the guidelines.

Interpretation of results:

other: not highly flammable

Conclusions:

The preliminary screening test was performed for the determination of the flammability of the substance in accordance with United Nations (UN) Test N.1 (2009), EU Method A.10 (2008) and according to GLP principles. As no propagation of combustion of the test substance along 200 mm length of the pile within 4 minutes was observed, the substance is considered not highly flammable. This result is read across.

Description of key information

Based on a study and experience during handling of the substance under normal laboratory conditions, the substance is considered to be non flammable. With the Pensky-Martens closed cup method was determined with a related member of the chemical category (amphoacetates C12) that aqueous solutions of the substance have no flash-point.

Key value for chemical safety assessment

Flammability:

non flammable

Additional information

The preliminary screening test was performed for the determination of the flammability of a substance analogue in accordance with United Nations (UN) Test N.1 (2009), EU Method A.10 (2008) and according to GLP principles. A freeze dried aqueous solution was used in this study. As no propagation of combustion of the test substance along 200 mm length of the pile within 4 minutes was observed, the substance is considered not highly flammable. This result is read across.

The molecular structure of the components of the substance was evaluated for the presence or absence of groups (metals or metalloids) that might lead to ignition in contact with water and/or to the evaluation of a flammable gas. As the molecular structure of the components of the substance does not contain such groups, the substance is considered "not highly flammable" in contact with water.

Based on experience during handling under normal laboratory conditions, it was concluded that the substance has no pyrophoric properties.

The Pensky-Martens closed cup method was applied for the determination of the flash-point of an aqueous solution of a related member of the chemical category (amphoacetates C12), according to UN, EC, ISO and ASTM guidelines and according to GLP principles. No flash-point was observed up to boiling of the test substance. The read-across from the other member of the chemical category alkylamphoacetates to the registered substance for flammability is considered scientifically justified based on the overall information available (see report for the category approach in IUCLID chapter 13).

Justification for classification or non-classification

Based on the results obtained in the preliminary screening test performed with the substance in accordance with EU Method A.10 (2008), expert judgement based on the molecular structure of the components of the substance and experience during handling of the substance under normal laboratory conditions, the substance does not need to be classified for flammability in accordance with the CLP Regulation. As it was determined that aqueous solutions of the substance have no flash-point, also aqueous solutions of the substance do not need to be classified for flammability in accordance with the CLP Regulation.
