This test method determines the relative distribution of the individual C8 aromatic hydrocarbon isomers in the following xylene products: nitration grade xylene conforming to Specification D 843, xylenes for p-xylene feedstock conforming to Specification D 5211, and ten-degree xylene conforming to Specification D 846.
Formerly under the jurisdiction of Committee D16 on Aromatic Hydrocarbons and Related Chemicals, this test method was withdrawn in January 2006. This standard is being withdrawn without replacement due to its limited use by industry.
1.1 This test method determines the relative distribution of the individual C8 aromatic hydrocarbon isomers in the following xylene products:
1.1.1 Nitration grade xylene conforming to Specification D843.
1.1.2 Xylenes for p-Xylene feedstock conforming to Specification D5211.
1.1.3 Ten-degree xylene conforming to Specification D846.
1.2 The absolute concentration of hydrocarbon impurities typically found in commercially available mixed C8 aromatic hydrocarbons should be determined using Test Method D2360.
1.3 This standard does not purport to address all of the safety problems, 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. For specific hazard statements, see Section 8.
