Flash point
Administrative data
Link to relevant study record(s)
- Endpoint:
- flash point of flammable liquids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Study performed according to standard guideline with acceptable restrictions.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Deviations:
- not specified
- GLP compliance:
- no
- Remarks:
- but certified ISO 17025 : "testing laboratory for safety testing in the field of chemistry, protection against explosion and fire, electrostatic, storage, transport"
- Type of method:
- closed cup
- Remarks:
- Pensky-Martens method
- Flash point:
- > 110 °C
- Atm. press.:
- 1 013 mBar
- Conclusions:
- No ignition of the test substance was observed up to 110°C. Above this temperature the test substance was refluxing. According to DSD and CLP regulations phosphinic acid 60% is out of any hazard category and therefore is classified as not flammable
- Executive summary:
Flash point of phosphinic acid 60% has been measured in a Pensky-Mertens method according to method A1 requirements from regulation (CE) n°440/2008 with acceptable restrictions.
The result of three independent measurements at 1013 mBar showed not flammability up to 110°C.
No ignition of the test substance was observed up to 110°C. Above this temperature the test substance was refluxing.
According to DSD and CLP regulations phosphinic acid 60% is out of any hazard category and therefore is classified as not flammable.
Reference
No ignition of the test substance was observed up to 110°C. Above this temperature the test substance was refluxing.
Description of key information
One key data was obtained on phosphinic acid in aqueous solution at 60 % according to standard guideline. No ignition of the test substance was observed up to 110°C. Above this temperature the test substance was refluxing. Phosphinic acid 60% is out of any hazard category and therefore is classified as not flammable under DSD and CLP regulations.
Key value for chemical safety assessment
Additional information
Flash point of phosphinic acid 60% aqueous solution has been measured in a Pensky-Mertens method according to method A1 requirements from regulation (CE) n°440/2008 with acceptable restrictions. The result of three independent measurements at 1013 mBar showed not flammability up to 110°C. Above this temperature the test substance was refluxing.
Therefore, it is concluded that no ignition of the test substance was observed up to 110°C.
According to DSD and CLP regulations phosphinic acid 60% is out of any hazard category and therefore is classified as not flammable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
