Sample mass = 19.39 mg

Onset of endotherm detected at 60 ºC. The integrated endotherm gave ΔH = 122 J/g.

Onset of exotherm detected at 280 ºC. The integrated exotherm gave ΔH = -281 J/g.

Conclusions:

The integrated exotherm ΔH was less than 300 J/g. Thus the tested material is considered not to be self reactive.
The substance is considered to be stable at room temperature according to the criteria set out in OECD Guideline 113 (no decomposition observed <150°C).

Thermal stability: No thermal effect (peak) found between room temperature and 150 °C, except the melting point of the substance (approx. 69 °C).

Thermal stability in air: No thermal effect (peak) found between room temperature and the melting point of the substance (approx. 69 °C).

Conclusions:

The study is considered to be adequate and reliable.

Executive summary:

The substance is thermally stable at relevant temperatures, without and with the presence of air.

Description of key information

thermally stable (Schürch, DTA, with air, tested up to 69 °C)

thermally stable (Schürch, DTA, without air, tested up to 150 °C)

not self-reactive (Bailey, DSC)

not self-reactive (Bailey, DSC)

Additional information

Three studies are available. All are considered to be reliable and adequate, and are carried forward for use in risk assessment, classification and labelling.

The substance is considered to be stable at room temperature.

Waivers for "self-heating properties" and "corrosive properties to metals" are provided to document the corresponding non-classification (CLP).

Justification for classification or non-classification

The integrated exotherm ΔH (screening test) was less than 300 J/g. The substance does not meet the criteria for classification (see Regulation (EC) No. 1272/2008, Annex I, Part 2, section 2.8.2.1 (d)). The available experimental test data are considered reliable, suitable for classification purposes and conclusive.
