Additional information

The Pocket Guide presents key information and data from the US Department of Health and Human Services and as such is a reliable governmental source of information and is considered a suitable key study for this endpoint (NIOSH 2005). The WHO ICSC (2005) indicates that the flash point of the test substance is 32°C. No information on the primary source of the data or the methods used is available. However, this information is taken from a reliable peer reviewed database and so can be considered reliable and suitable for use as the supporting study for this endpoint

The flash point of commercial DCPD was taken from proprietary data. There is no information on the GLP status of the study or the methods used but the results are taken from company specific datasheets and are considered to be suitable for use for this endpoint.
