ASTM D8230-19

5.1 Silica generated from the combustion of gases containing siloxane compounds can damage internal combustion engines or microturbine blades, reduce heat transfer efficiency of landfill gas and biogas equipment, and poison catalytic oxidizers that are used to control regulated volatile organic compound emissions. The ability to analyze siloxanes in biologically derived fuel gases and other gaseous fuel matrices is highly desirable in order to assess the initial siloxane content and the efficacy of gas pretreatment measures.

1.1 This test method is primarily for gas-phase siloxane compounds present in biogas and other gaseous fuel samples at ppmv and high ppbv concentrations. It may also be applicable to low ppbv concentrations under certain circumstances.

1.2 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.

1.3 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.
