Standard Specification for Glacial Methacrylic Acid (Withdrawn 2011)

ABSTRACT
This specification establishes the properties and requirements for glacial methacrylic acid for use in paint, varnish, lacquer, and related products. Specimens shall be appropriately sampled and tested, and shall adhere to specified requirements as to assay from total acidity by titration, weight, weight of water, color (Pt-Co scale), and inhibitor (methyl of hydroquinone).
SCOPE
1.1 This specification covers glacial methacrylic acid (98.5 % grade) for use in paint, varnish, lacquer, and related products.
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 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.3 For hazard information and guidance, see the supplier's Material Safety Data Sheet.
WITHDRAWN RATIONALE
This specification covers glacial methacrylic acid (98.5 % grade) for use in paint, varnish, lacquer, and related products.
Formerly under the jurisdiction of Committee D01 on Paint and Related Coatings, Materials, and Applications, this specification was withdrawn in June 2011 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the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.
