NOTE 13—If it suspected that the recommended sample size will foul
the electrodes, a smaller sample size can be taken. Results using smaller
sample size may not be equivalent to results obtained with the recommended
sample size. The precision statement does not include results
when using a smaller sample size.
NOTE 14—A titration solvent that contains chloroform (Warning
—May be fatal if swallowed. Harmful if inhaled. May produce toxic
vapors if burned) can be used in place of toluene to completely dissolve
certain heavy residues of asphaltic materials. Results using chloroform
may not be equivalent to results obtained using toluene. The precision
statement does not include results when using chloroform.
