Reference
Determination of the Burning Rate |
|
Preparations before the Test: |
The test item was loosely filled into a mould. Then the mould was dropped three times from a height of 2 cm onto a solid surface. The lateral limitations were removed and the excess substance was scraped off. A non-combustible and non-porous plate was placed on top of the mould. This was inverted and the mould removed. |
Preliminary Test: |
The pile was ignited with the flame (minimum diameter 5 mm) of a gas burner. The flame was applied to the end of the pile for two minutes. The test item was observed for a total of 4 minutes. The test item did not ignite. |
Main Test: |
As the test item could not be ignited in the preliminary test no further testing of the burning rate was required. |
Description of key information
Flammability: non flammable (EU Method A.10, GLP)
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
The potential flammability of Dicalcium pyrophosphate
(CAS 7790-76-3, EC 232-221-5) was evaluated in a study conducted
according to EU Method A.10 and GLP (Wagner-Rivas, 2015). The
test item Dicalcium pyrophosphate was
used in its initial form.
The
test item could
not
be ignited. Therefore, the test item is considered to be not flammable.
Justification for classification or non-classification
The available data indicate that the substance does not meet the classification criteria in accordance with Regulation (EC) No 1272/2008 (CLP) and the Globally Harmonized System of Classification and Labelling of Chemicals (GHS).
CLP
Flammability: not classified
GHS
Flammability: not classified
