During the definitive boiling point testing the test substance samples provided a corrected mean boiling point of 563.1 ± 1.4K and a mean corrected boiling range from 447.4 ± 1.0K to 563.1 ± 1.4K (for the three tests). Upon melting, the test substance was clear and light yellow. Upon removal from the instrument (at test termination), the test substance was amber in color. Results of the uncorrected boiling point determinations for the test substance are presented in Table 3. Table 4 contains the normalized (normal) boiling point data (corrected to standard barometric pressure).
