Reference
Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Qualifier:
equivalent or similar to guideline
Guideline:
other: EC Regulation No.440/2008 Appendix A.10 Flammability(Solids)
Principles of method if other than guideline:
The test is carried out according to 33.2.1.4 in “EC Regulation No.440/2008 Appendix A.10 FLAMMABILITY(SOLIDS)”. The sample is formed a train by a specified mould; then burn one end of the train, observe and record the phenomena of combustion and the burning time.
GLP compliance:
no
Other quality assurance:
ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
Test procedure:
burning rate test: preliminary screening test
Burning time:
>= 45 s
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 method of assessing result is shown in Table3,where the mark“√”means a positiveresult.
