Applicant's summary and conclusion
- Conclusions:
- The melting/freezing temperature of the test material has been determined to be > 633 ± 0.5 K.
As no melting occurred up to 360ºC, no determination of boiling temperature was required. - Executive summary:
For substance MOS-HIGE in project number 1456 -0064, the melting/freezing temperature of the test material has been determined to be > 633 ± 0.5 K. As no melting occurred up to 360ºC, no determination of boiling temperature was required. The determination was carried out by differential scanning calorimetry (DSC) using the procedure specified in ASTM E537-86, Methods A1 and A2 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).
