This standard is equivalent translation ISO 10283.2007. For ease of use, this standard editorial changes as follows. --- Use the "standard" instead of "this International Standard"; --- Delete international standards foreword. This standard replaces GB /Determination of urethane prepolymers and coatings solution unreacted toluene T 18446-2001 "Gas Chromatography Diisocyanate (TDI) monomer. " This standard GB/T 18446-2001 and the main technical differences are as follows. --- Increasing the range of the species can be determined diisocyanate monomer; --- Using capillary column Determination diisocyanate monomer; --- Using tetradecane or anthracene as an internal standard; --- Improving the precision of the test method. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee paint pigment. This standard was drafted. CNOOC Changzhou coating Chemical Research Institute. The main drafters of this standard. to shore. This standard replaces the standards previously issued as follows. --- GB/T 18446-2001. GB/T 18446-2009/ISO 10283.2007 Paints and varnishes isocyanate resin Determination of diisocyanate monomer1 ScopeThis standard specifies the determination diisocyanate monomer content by gas chromatography method. This standard applies to different definitions of Chapter 3 Cyanate ester resin and a resin solution prepared from such (Preparation of a coating for the coating material and the like) of a toluene diisocyanate), six Methylene diisocyanate, isophorone diisocyanate 2), diphenyl methane diisocyanate 3) and other types of diisocyanate content Determination. 1) The term "toluene diisocyanate" as used here and in the text refers to the 4-methyl-1,3-phenylene diisocyanate (2,4-toluene diisocyanate) and 2-methyl Phenylene-1,3-diisocyanate (2,6-toluene diisocyanate). 2) here and in the text, the term "isophorone diisocyanate" refers to 2-isocyanato-methyl -3,5,5-trimethyl-cyclohexyl isocyanate. This article fit When used at (Ⅰ) and (Ⅱ) to identify stereoisomers. 3) here and in the text, the term "diphenyl methane diisocyanate" refers to 4,4-diphenyl methane diisocyanate, 2,4-diphenylmethane diisocyanate Dioxane and 2,2-diphenyl methane diisocyanate.2 Normative referencesThe following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Whether the latest versions of these documents.
