|Significance and Use|
4.1 The presence of water in PTA used for the production of polyester is undesirable because it reduces the purity of the PTA.
4.2 Determining the amount of water content remaining from the manufacture of PTA is often required. This test method is suitable for setting product specifications and for use as an internal quality control tool where these products are produced or are used.
1.1 This test method covers the determination of water in purified terephthalic acid (PTA) between 0.01 and 1.00 % (w/w) by Volumetric Karl Fischer Titration.
1.2 In determining the conformance of the test results using this method to applicable specification, results shall be rounded off in accordance with the rounding-off method of Practice .
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
