(Test Method)Standard Test Method for Purity of Acrylate Esters by Gas Chromatography (Withdrawn 2011)
Standard Test Method for Purity of Acrylate Esters by Gas Chromatography (Withdrawn 2011)
SIGNIFICANCE AND USE
This test method provides a measurement of commonly found impurities in commercially available methyl acrylate, ethyl acrylate, butyl acrylate, and 2-ethylhexyl acrylate. The measurement of these impurities and the results thereof can either individually or when totaled and subtracted from 100 (assay) be used for specification purposes.
SCOPE
1.1 This test method covers the determination of the purity of acrylate, ethyl acrylate, n-butyl acrylate, and 2-ethylhexyl acrylate by gas chromatography and, in addition, provides a means for measuring certain impurities such as alcohols and other esters. Water and acidity are measured by other appropriate ASTM procedures and the results are used to normalize the chromatographic values.
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 E 29.
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 hazard information and guidance, see the supplier's Material Safety Data Sheet.
1.5 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 7.
WITHDRAWN RATIONALE
This test method covers the determination of the purity of acrylate, ethyl acrylate, n-butyl acrylate, and 2-ethylhexyl acrylate by gas chromatography and, in addition, provides a means for measuring certain impurities such as alcohols and other esters. Water and acidity are measured by other appropriate ASTM procedures and the results are used to normalize the chromatographic values.
Formerly under the jurisdiction of Committee D01 on Paint and Related Coatings, Materials and Applications, this test method was withdrawn in June 2011 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
