Designation: E2470 − 26Standard Specif i cation forPolyester Grade Ethylene Glycol 1This standard is issued under the f i xed designation E2470; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (´) indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specif i cation covers polyester grade ethylene gly-col.1.2 The following applies to all specif i ed limits in thisstandard; for purposes of determining conformance with thisstandard, an observed value or a calculated value shall berounded off “to the nearest unit” in the last right-hand digitused in expressing the specif i cation limit, in accordance withthe rounding-off method of Practice E29.1.3 Consult current OSHA regulations, suppliers’ SafetyData Sheets, and local regulations for all materials used in thisspecif i cation.1.4 Units—The values stated in SI units are to be regardedas standard. No other units of measurement are included in thisstandard.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety, health, and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade (TBT) Committee.2.
