pdfWorksheet -- Physical And Chemical Properties
You are not required to complete this worksheet. It is an optional summary presentation of the data you are submitting, and is intended to assist in the review of the
physical and chemical properties data. This worksheet is also intended to help in the understanding of the types of characterization data typically available for
engineered nanoscale materials. If data is not provided, please help us understand why if wasn’t provided.
Please complete the following worksheet by identifying the property measured; the value of the property; the units in which the property is measured or estimated (as
necessary); whether it is a measured or estimated value; the name of the method used to obtain the data; the page on which the data is provided, or if not provided, an
indication of why is wasn’t provided; and, whether or not the value is claimed as confidential. If non-standard methods were used in the collection of data, EPA would
also be interested in receiving a brief description of the alternate method.
The physical state of the neat substance should be measured for the neat (100% pure) chemical substance. Properties that are measured for mixtures or formulations
should be so noted (% substance in __). In addition, please provide any nanoscale material specific chemical and physical characterization data.
