the study was carried out between 21 April 2017 and 7 June 2017
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
EU Method A.10 (Flammability (Solids))
GLP compliance:

Specific details on test material used for the study:
Identification: LA-63P
Appearance/Physical state: White powder
Chemical name: 1,2,3,4-Butanetetracarboxylic acid, tetramethyl ester, reaction products with1,2,2,6,6-pentamethyl-4-piperidinol and β,β,β’,β’-tetramethyl-2,4,8,10-tetraoxaspiro[5.5]undecane-3,9-diethanol
Batch: 112Z5
Purity: 100%
Expiry date: 30 June 2017
Storage conditions: Room temperature in the dark
Key result
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

The pile melted and failed to ignite during the 2 minutes that the Bunsen flame was applied.

The result of the preliminary screening test obviated the need to perform the main test.

Interpretation of results:
not classified based on GHS criteria
The test item has been determined to be not highly flammable as it failed to ignite in the preliminary screening test.
Executive summary:

Flammability (Solids). Not highly flammable, using a procedure designed to be compatible with Method A.10 Flammability (Solids) of Commission Regulation (EC) No 440/2008 of 30 May 2008.
