Executive summary:

The test was designed to be compatible with the following guidelines and recommendations of EPA/OCSPP 830.6302. 6303 and 6304.


The colour of the test substance was assessed under normal daylight by the Munsell colour system to be N 9.5. This was described as off-white to white in colour.


The physical state of the test item was assessed at 20°C. The test substance was observed to be a solid (powder).


Due to the potentially hazardous nature of the test item, the odour was not directly assessed; however, any odour detected whilst handling the material was recorded. No discernible odour was noted while working with the test substance.
