Reference
Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
07 September 2015 to 10 December 2015
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
Deviations:
no
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))

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

In contact with the flame of the gas burner the test item melted, emitted yellow sparks and turned into a black residue. White smoke was observed. After removal of the ignition source, no propagation of combustion of the test item was observed.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
No propagation of combustion of the test item along 200 mm length of the pile within 4 minutes was observed. According to the guidelines, performance of the burning rate test is not required. Based on the results obtained the test item is considered ‘not highly flammable’.
Executive summary:

The purpose of the study was to determine the physico-chemical properties for Formaldehyde, oligomeric reaction products with acetone and diphenylamine.

 

The study was performed to the following guidelines, in compliance with GLP:

European Community (EC), EC no. 440/2008, Part A: Methods for the Determination of Physico-Chemical Properties, Guideline A.10: “Flammability (Solids)”, Official Journal of the European Union no. L142, May 31, 2008.

United Nations (UN), UN no. ST/SG/AC.10/11/Rev.5: Recommendations on the Transport of Dangerous Goods, Part III: Classification Procedures, Test Methods and Criteria Relating to Class 2, Class 3, Class 4, Division 5.1, Class 8 and Class 9, Test N.1: “Test Method for Readily Combustible Solids”, 2009.   

 

The preliminary screening test was performed for the determination of the flammability of Formaldehyde, oligomeric reaction products with acetone and diphenylamine.

 

No propagation of combustion of the test item along 200 mm length of the pile within 4 minutes was observed. According to the guidelines, performance of the burning rate test is not required. Based on the results obtained the test item is considered ‘not highly flammable’.
