ASTM D5932-08-e1-Reapproved2013<\/h3>\n

Historical Standard: Standard Test Method for Determination of 2,4-Toluene Diisocyanate (2,4-TDI) and 2,6-Toluene Diisocyanate (2,6-TDI) in Air (with 9-(N-Methylaminomethyl) Anthracene Method) (MAMA) in the Workplace<\/h4>\n

ASTM D5932<\/h4>\n

Scope<\/strong><\/p>\n

\n

1.1<\/span> This test method covers the determination of gaseous 2,4-toluene diiso<\/span>cyanate (2,4-TDI) and 2,6-toluene diiso<\/span>cyanate (2,6-TDI) in air samples collected from workplace and ambient atmospheres.<\/p>\n<\/p><\/div>\n

\n

1.2<\/span> Differential air sampling is performed with a segregating device.2<\/span><\/span>,<\/sup>3<\/span><\/span> The gaseous fraction is collected on a glass fiber filter (GFF) impregnated with 9-(N-methylaminomethyl) anthracene (MAMA).<\/p>\n<\/p><\/div>\n

\n

1.3<\/span> The analysis of the gaseous fraction is performed with a high performance liquid chromatograph (HPLC) equipped with ultraviolet (UV) and fluorescence detectors.<\/p>\n<\/p><\/div>\n

\n

1.4<\/span> The analysis of the aerosol fraction is performed separately as described in Ref (1<\/span>)<\/span>.4<\/span><\/span><\/p>\n<\/p><\/div>\n

\n

1.5<\/span> The range of application of this test method, utilizing UV and a fluorescence detector, is validated for 0.029 to 1.16 \u03bcg of monomer 2,4- and 2,6-TDI\/2.0 mL of desorption solution, which corresponds to concentrations of 0.002 to 0.077 mg\/m3<\/sup> of TDI based on a 15-L air sample. This corresponds to 0.28 to 11 ppb(V) and brackets the established TLV value of 5 ppb(v).<\/p>\n<\/p><\/div>\n

\n

1.6<\/span> A field blank sampling system is used to check the possibility of contamination during the entire sampling and analysis.<\/p>\n<\/p><\/div>\n

\n

1.7<\/span> The values stated in SI units are to be regarded as the standard.<\/p>\n<\/p><\/div>\n

\n

1.8<\/span> 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.<\/i><\/p>\n<\/p><\/div>\n
