ASTM D8534-23

Standard Test Method for Determination of Trace Peroxides in Liquid, Liquefied, and Reagents Soluble Hydrocarbon Streams using Flow Injection System with Ultraviolet/Visible Detector

SIGNIFICANCE AND USE
5.1 This test method is suitable for determining the quantity of hydrogen peroxide, organic hydroperoxides, and organic peroxides as total active oxygen in various hydrocarbon streams for both quality control and quality assurance of the product.
SCOPE
1.1 This test method covers the determination of trace peroxides in various hydrocarbon streams. A list of typical hydrocarbon streams can be found in Appendix X2.  
1.2 This test method is applicable to the determination of peroxides in petroleum liquids including, but not limited to, 1,3-butadiene, styrene, methylcyclohexane, and alpha olefins in the range of 0.1 mg/kg to 100 mg/kg active oxygen. The limit of detection (LOD) is 0.03 mg/kg for active oxygen and the limit of quantitation (LOQ) is 0.11 mg/kg active oxygen. The upper limit has been determined by the calibration range.  
Note 1: LOD and LOQ were calculated using data obtained during development of the method.  
1.3 In determining the conformance of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29.  
1.4 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 9.  
1.6 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.
