Applicant's summary and conclusion

Conclusions:
Using a linear heating rate of 0.5°C/min, Reactive Orange F08-0314 did not melt up to 400°C.

During the tests the following transformation temperatures were recorded:

1. Start of transition: The test item darkened.
2. 2nd step of transition: The colour of the test item changed dark brown.
3. Final stage of transition: The colour of the test item changed black.

No liquid phase was observed up to 400°C.
Executive summary:

Study performed to Commission Regulation (EC) No 440/2008 of 30 May 2008 laying down test methods pursuant to Regulation (EC) No 1907/2006 of the European Parliament and of the Council on the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), Method A.1, Official Journal of the European Union L 142 of 31 May 2008 and Organisation for Economic Co-operation and Development (OECD), Guidelines for Testing of Chemicals, Guideline No. 102, “Melting Point / Melting Range”; adopted July 27, 1995. This study is compliant with the Principles of Good Laboratory Practice (GLP) and reported with a valid GLP certificate.

 

For the determination of the melting point or melting range, the capillary method was used. A small amount of the test item was heated in the electronic controlled sample block and the temperature around the sample was displayed. The sample was observed visually while raising the temperature. The initial and final melting temperatures were determined.

Using a linear heating rate of 0.5°C/min, Reactive Orange F08-0314 did not melt up to 400°C.

 

No melting point was observed up to 400°C.
