This study and the conclusions which are drawn from it fulfil the quality criteria (validity, reliability, repeatability). - Executive summary:
A study was performed to determine the melting temperature of the test item according OECD Method 102 and U.S. EPA. Test Guidelines, OPPTS 830.7200. The melting temperature was determined using the caplillary/metal block method . Subsamples of the test substance were heated in melting point capillary tubes in a temperature-controlled heating block. Measurement of melting points was limited to ≤ 400°C (approximately 673K), the maximum specified for the instrumentation used. The temperature at which fine droplets adhered uniformly to the wall of the melting point tube was accepted as the melting point. The definitive melting point testing provided a mean melting point of 128.5 ± 0.1°C (401.7K) and a mean melting range from 128.5 ± 0.1°C (401.7K) to 131.3 ± 0.1°C (404.4K) - for the three tests. Upon melting, the test substance appeared clear.
