ASTM D6832-13<\/h3>\n

Historical Standard: Standard Test Method for the Determination of Hexavalent Chromium in Workplace Air by Ion Chromatography and Spectrophotometric Measurement Using 1,5-diphenylcarbazide<\/h4>\n
\n

ASTM D6832<\/h4>\n

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

\n

1.1 This test method specifies a method for the determination of the time-weighted average mass concentration of hexavalent chromium in workplace air samples.<\/p>\n<\/p><\/div>\n

\n

1.2 The method is applicable to the personal sampling of the inhalable fraction of airborne particles, as defined in ISO\u20097708, and to area (static) sampling.<\/p>\n<\/p><\/div>\n

\n

1.3 The sample dissolution procedure specifies separate procedures for soluble and insoluble hexavalent chromium.<\/p>\n<\/p><\/div>\n

\n

1.4 The method is applicable to the determination of masses of 0.01 \u03bcg to 10 \u03bcg of hexavalent chromium per sample without dilution.<\/p>\n<\/p><\/div>\n

\n

1.5 The concentration range for hexavalent chromium in air for which this procedure is applicable is approximately 0.1 \u03bcg\/m 3<\/sup> to 100 \u03bcg\/m3<\/sup>, assuming 1 m3<\/sup> of air sample. The range can be extended upwards by appropriate dilution.<\/p>\n<\/p><\/div>\n

\n

1.6 Interconversion of trivalent and hexavalent chromium species may occur during sampling and sample preparation, but these processes are minimized to the extent possible by the sampling and sample preparation procedures employed.<\/p>\n<\/p><\/div>\n

\n

1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.<\/p>\n<\/p><\/div>\n

\n

1.8 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
