These test methods provide for the determination of color and various impurities in acrylonitrile. Color and impurity levels are important factors in many uses of acrylonitrile.

1.1 These test methods cover the analysis of acrylonitrile.

1.2 The analytical procedures appear in the following order:

	Sections
Color	7 to 9
Hydrogen Cyanide	10 to 18
p-Methoxyphenol	19 to 28
Water	29 to 32

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 Review the current Material Safety Data Sheets (MSDS) for detailed information concerning toxicity, first aid procedures, and safety precautions.

1.5 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. See Section 5 for specific hazards statements.

10.1 This test method covers the determination of HCN over the concentration of 0.5 to 10 μg/g in acrylonitrile.
