1、Designation: D 4709 07Standard Specification forMethyl Acrylate1This standard is issued under the fixed designation D 4709; 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 indicate

2、s the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers methyl acrylate (99 % grade)for use in paint, varnish, lacquer, and related products.1.2 The following applies to all specified limits in

3、 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 specification limit, in accordance withthe rounding-off method of Practice E29.1.3 The values

4、 stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.4 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 safet

However, it is not knownwhether methyl acrylate was part of the sample set included in theinterlaboratory study.4. Hazards4.1 Methyl acrylate is a flammable liquid. Its vapors canform explosi

11、ve mixtures with air and are particularly irritating.Store samples in amber bottles or protect from light by othermeans to aid in preventing polymerization. Keep samples awayfrom heat sources and chemicals that can cause free radicalpolymerization. Methyl acrylate can polymerize violentlyevolving co
