Notes:

Fm 305 Fraction measure factor in Method 305, 40 CFR 305 part 63, appendix A.

a CAS numbers refer to the Chemical Abstracts Services registry number assigned to specific compounds, isomers, or mixtures of compounds.

b Denotes a HAP that hydrolyzes quickly in water, but the hydrolysis products are also HAP chemicals.

c Denotes a HAP that may react violently with water.

d Denotes a HAP that hydrolyzes slowly in water.

e The Fm 305 factors for some of the more common glycol 305 ethers can be obtained by contacting the Waste and Chemical Processes Group, Office of Air Quality Planning and Standards, Research Triangle Park, NC 27711.
