Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Flammability
Administrative data
Link to relevant study record(s)
- 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
- 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.
- Test procedure:
- ignition time on contact with air
- Remarks:
- Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
- Remarks on result:
- no ignition on contact with air (not further specified)
- Remarks:
- corresponding to 'no' in migrated source record.
- Test procedure:
- ignition time on contact with air
- Remarks:
- Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
- Remarks on result:
- no ignition on contact with air (not further specified)
- Remarks:
- corresponding to 'no' in migrated source record.
- 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.

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

Silver metal is not considered to be of concern regarding pyrophoricity, flammability in contact with water and auto-flammability (waiving, studies scientifically unjustified).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
