CONTAINED IN VOL. 06.04, 2017 Defines purified terephthalic acid (PTA) for use in the manufacturing of polymers.

1.1This specification covers purified terephthalic acid (PTA) for use in the manufacturing of polymers. Some examples include the production of polyesters for fiber, filament, yarn, film, coating, bottle and resin applications.

1.2The following applies to all specified limits in this specification: for purposes of determining conformance with this specification, 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.

1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4Consult current OSHA regulations, supplier’s Safety Data Sheets, and local regulations for all materials used in this specification.

1.5This 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.
