This specification covers polyester grade ethylene glycol. Sampled specimens shall undergo tests, for which the following chemical and physical requirements should be met: acidity (as acetic acid); aldehydes (acetaldehyde) content; appearance; chloride content; color (Pt-Co scale); glycols (as ethylene and diethylene glycol) content; iron content; ultraviolet transmittance; water content; ash content; distillation range (initial boiling point and dry point); relative density; and water miscibility.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers polyester grade ethylene glycol.

1.2 The following safety hazards caveat pertains only to the test methods portion, Section 5, described in this specification: This 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.

1.3 Review the current Materials Safety Data Sheets (MSDS) for detailed information comcerning toxicity, first aid procedures, handling and safety precautions.

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

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
