1.1 This specification covers polyester grade ethylene glycol.
1.2 Review the current Materials Safety Data Sheets (MSDS) for detailed information concerning toxicity, first aid procedures, handling and safety precautions.
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 E 29.
1.4 The values stated in SI units are to be regarded as the standard.
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.
