ASTM D1257-22

Standard Specification for High-Gravity Glycerin

ABSTRACT
This specification covers high-gravity glycerin (98.7 weight%, minimum) for use in the manufacture of alkyd and other synthetic resins. The following properties of glycerin shall be determined: color, Pt-Co scale, sulfate ash content(weight%), and acid value.
SCOPE
1.1 This specification covers high-gravity glycerin (98.7 weight %, minimum) for use in the manufacture of alkyd and other synthetic resins.  
1.2 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.  
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.4 For specific hazard information and guidance, see the supplier's Material Safety Data Sheet for materials listed in this specification.  
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.
