(Test Method)Standard Test Method for Determination of Peroxides in Butadiene
Standard Test Method for Determination of Peroxides in Butadiene
SIGNIFICANCE AND USE
4.1 Due to the inherent danger of peroxides in butadiene, specification limits are usually set for their presence. This test method will provide values that can be used to determine the peroxide content of a sample of commercial butadiene.
4.2 Butadiene polyperoxide is a very dangerous product of the reaction between butadiene and oxygen that can occur. The peroxide has been reported to be the cause of some violent explosions in vessels that are used to store butadiene.
SCOPE
1.1 This test method covers the determination of peroxides in butadiene.
1.2 This test method covers the concentrations range of 1 mg/kg to 10 mg/kg as available oxygen.
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 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4.1 The user is advised to obtain LPG safety training for the safe operation of this test method procedure and related activities.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
