Significance and Use | ||||
This test method is useful for determining low levels of acidity, below 500 μg/g in acrylonitrile. The total acidity is calculated as acetic acid. Acidity may be present as a result of contamination or decomposition during storage, distribution, or manufacture. |

1. Scope | ||||
1.1 This test method covers the determination of total acidity as acetic acid in concentrations below 500 μg/g in acrylonitrile. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 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. Specific hazard statements are given in Section 8. 1.4 Review the current Material Safety Data Sheets (MSDS) for detailed information concerning toxicity, first aid procedures, and safety precautions. |
