【国外标准】 Standard Specification for Ethylene Glycol

This specification establishes the properties and requirements for ethylene glycol for use in the preparation of surface coatings. The material shall be appropriately sampled and tested, and shall conform to the following specified requirements: apparent specific gravity; color (Pt-Co units); distillation range (initial boiling point and dry point); water content; acidity as acetic acid; diethylene glycol content; and iron content.1.1 This specification covers ethylene glycol for use in the preparation of surface coatings.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.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 E29.1.4 For specific hazard information and guidance, consult the supplier's Material Safety Data Sheet.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
