Historical Standard: Standard Test Method for Maleic Acid in Maleic Anhydride by Potentiometric Titration
ASTM D2930
Scope
1.1 This test method covers the determination of free maleic acid in refined maleic anhydride by potentiometric titration.
1.2 This test method is applicable for all concentrations of maleic acid; however, it is primarily used for concentrations below 0.5%.
1.3 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.
