Type of information:
experimental study
Adequacy of study:
key study
Study period:
10.09.2011 - 17.09.2011
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Justification for type of information:
Data is from experimental study report
Qualifier:
according to guideline
Guideline:
other: as mentioned below
Principles of method if other than guideline:
It is how easily substance can burn or ignite, causing fire or combustion by brief contact with an ignition source (such as a burning match)
GLP compliance:
no
Other quality assurance:
ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
Specific details on test material used for the study:
- Common name: Potassium iodate
- Molecular formula: HIO3.K
- SMILEY: [K+].[O-][I](=O)=O
- InChi: 1/HIO3.K/c2-1(3)4;/h(H,2,3,4);/q;+1/p-1/fIO3.K/q-1;m
- Substance type: Inorganic
- Physical state: Solid
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. | Remarks: | Additional remarks: Potassium iodate was found to be non flammable since the sample did not ignite when a source of ignition in the form of bunsen burner was brought in close contact with the sample.
