【国外标准】 Standard Specification for n-Butyl Acrylate (Withdrawn 2011)

This specification covers n-butyl acrylate (99 % grade) for use in paint, varnish, lacquer, and related products. This material shall be subjected to the following tests: purity test, water test, color test, acidity test, and hydroquinone methyl ether level test. For safety harzards, butyl acrylate samples must be stored in amber bottles or protect them from light by other means to aid in preventing polymerization. Keep samples away from heat sources and chemicals that can cause free radical polymerization. Butyl acrylate can polymerize violently evolving considerable heat.1.1 This specification covers n-butyl acrylate (99 % grade) for use in paint, varnish, lacquer, and related products.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 E 29.1.4 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. Specific hazard statements are given in 4.1.1.5 For specific hazard information and guidance, consult supplier's Material Safety Data Sheet.
