1.1 These test methods cover the determination of major organic impurities in refined phenol manufactured by the cumene (isopropylbenzene) process. Two test methods are employed to determine the stated major impurities.

1.2 Test Method A determines the concentration of major impurities such as mesityl oxide, cumene, [alpha]-methylstyrene, 2-methylbenzofuran, acetophenone, and dimethylbenzyl alcohol.

1.3 Test Method B determines the hydroxyacetone content.

1.4 The following applies to all specified limits in this standard: for purposes of determining conformance with this standard, an observed value or a calculated value shall be rounded off "to the nearest unit" in the last right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E29.

1.5 This standard does not purport to address all of the safety problems, if any, associated with its use.
