- Executive summary:
The test item Tris(hydroxymethyl)phosphine oxide (THPO) has a no flash point up to the boiling at approx. 148 °C according to Regulation EC No. 440/2008 Method A.9. Flash Point and DIN EN ISO 2719 (2003).
According to the results of the test on the flash point, the test item is classified as following:
- UN Transport Regulation: As the test item shows no flash point up to the boiling at approx. 148 °C, it has not to be classified in class 3 as flammable liquid.
- GHS (CLP Regulation EC 1272/2008 Annex 1: 2.6): As the test item shows no flash point up to the boiling at approx. 148 °C, it has not to be classified as flammable liquid.

Description of key information
flash point (determined using EU Method A.9 / DIN EN ISO 2719 (2003); GLP): no flash point up to the boiling at approx. 148 °C
Key value for chemical safety assessment
Additional information
The flash point of the test material was determined using EU Method A.9 / DIN EN ISO 2719 (2003).
A reliability score of 1 was assigned, in accordance with the criteria for assigning data quality in line with the principles described by Klimisch (1997).
According to the results of the test on the flash point, the test item is classified as following:
- UN Transport Regulation: As the test item shows no flash point up to the boiling at approx. 148 °C, it has not to be classified in class 3 as flammable liquid.
- GHS (CLP Regulation EC 1272/2008 Annex 1: 2.6): As the test item shows no flash point up to the boiling at approx. 148 °C, it has not to be classified as flammable liquid.
