Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 03 February -06 April 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7200 (Melting Point / Melting Range)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- capillary method
- Melting / freezing pt.:
- > 400 °C
- Conclusions:
- No melting point of the test material according to the criteria described in the guideline could be observed up to 400 °C.
Reference
The determination of the melting point was performed by visual judgement using the capillary method.
In the preliminary test up to 400 °C no melting point as described in the guideline could be observed. No colour or physical state changes were noted.
Description of key information
Melting point: > 400 °C (EU Method A.1, GLP)
Key value for chemical safety assessment
Additional information
The melting/freezing temperature of diphosphoric acid, compound with 1,3,5-triazine-2,4,6-triamine (1:2) was determined by the capillary method using an electronically controlled heating system in a study conducted according to EU Method A.1 and GLP (Wagner-Rivas V, 2017). The melting point of the test material was determined to be greater than 400 °C.
