1.1This test method covers the determination of acid number in terephthalic acid (TA) by automatic potentiometric titration. As the index of TA purity, acid number is usually within 674 to 676 mg KOH/g.
1.2In determining the conformance of the test results using this method, results shall be rounded off in accordance with the rounding-off method of Practice E29.
1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
