ASTM E1534-93(2019)
(Test Method)Standard Test Method for Determination of Ash Content of Particulate Wood Fuels
Standard Test Method for Determination of Ash Content of Particulate Wood Fuels
SIGNIFICANCE AND USE
5.1 The ash content determines the weight of the noncombustible part of a particulate wood fuel that oxidizes during a combustion process but releases no energy.
SCOPE
1.1 This test method covers the determination of ash expressed as the percent of residue remaining after dry oxidation of particulate wood fuels. Particulate wood fuels are defined in Terminology E1126.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 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.
