Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2009-07-14 to 2009-08-14
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: GLP guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.10 (Flammability (Solids))
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Remarks:
signed 2004-09-06
Test procedure:
burning time (test type not further specified)
Remarks:
or specified in description of method (migrated information)
Burning time:
0 s
Remarks on result:
other: The test item could not be ignited with a flame.

The test item could not be ignited with a flame. A main burning rate test was therefore not necessary.

Interpretation of results:
non flammable
Remarks:
Migrated information
Conclusions:
The test item could not be ignited with a flame. A main burning rate test was therefore not necessary.
Endpoint:
substances / mixtures which in contact with water emit flammable gases
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water
Endpoint:
pyrophoric solids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied

Description of key information

Silver metal powder has been shown to be non-flammable in contact with a hot flame (experimental results, study in accordance with EU method A.10). Silver metal is not considered to be of concern regarding pyrophoricity, flammability in contact with water and auto-flammability (waiving, studies scientifically unjustified).

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

Justification for classification or non-classification

Silver metal powder has been shown to be non-flammable in contact with a hot flame (experimental results, study in accordance with EU method A.10). Silver metal is not considered to be of concern regarding pyrophoricity, flammability in contact with water and auto-flammability (waiving, studies scientifically unjustified).
