1、Designation: D3734 05 (Reapproved 2010)Standard Specification forHigh-Flash Aromatic Naphthas1This standard is issued under the fixed designation D3734; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A n
2、umber in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification covers two types of aromatic hydro-
3、carbon solvents, normally petroleum distillates, having highflash points, moderately low volatility, and a distillation rangeof approximately 30C (50F). These solvents are used prima-rily by the coatings industry and are commonly referred to ashigh-flash aromatic naphthas.1.2 The values stated in SI
4、 units are to be regarded as thestandard. The values given in parentheses are for informationonly.1.3 The following applies to all specified limits in thisstandard; for purposes of determining conformance with thisstandard, an observed value or a calculated value shall berounded off “to the nearest
5、unit” in the last right-hand digitused in expressing the specification limit, in accordance withthe rounding-off method of Practice E29.1.4 For specific hazard information and guidance, see thesuppliers Material Safety Data Sheet for materials listed in thisspecification.2.
