- experimental study
- Adequacy of study:
- key study
- Study period:
- 22 November 2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Reason / purpose for cross-reference:

- Type of method:
- other: Capillary/metal block
- Key result
- Melting / freezing pt.:
- >= 63.4 - <= 63.9 °C
- Conclusions:
- Under the conditions of this study the melting range of the test material was 63.4 to 63.9 °C.
- Executive summary:
The melting temperature of the test material was determined in accordance with the standardised guideline OECD 102 using the capillary/metal block method.
A capillary tube was filled and placed in a heated metal block. The temperature rise was adjusted to a suitable preselected linear rate and a beam of light was then directed through the sample to a photocell. On melting of the sample, the intensity of the light reaching the photocell increases and a stop signal was sent to the digital indicator reading out the temperature of the heating chamber.
Under the conditions of this study, the melting range of the test material was 63.4 to 63.9 °C.

Additional information
The melting temperature of the test material was determined in accordance with the standardised guideline OECD 102 using the capillary/metal block method. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
A capillary tube was filled and placed in a heated metal block. The temperature rise was adjusted to a suitable preselected linear rate and a beam of light was then directed through the sample to a photocell. On melting of the sample, the intensity of the light reaching the photocell increases and a stop signal was sent to the digital indicator reading out the temperature of the heating chamber.
Under the conditions of this study, the melting range of the test material was 63.4 to 63.9 °C.
