(Test Method)Standard Test Method for Volatile Matter in the Analysis of Particulate Wood Fuels
Standard Test Method for Volatile Matter in the Analysis of Particulate Wood Fuels
SIGNIFICANCE AND USE
4.1 The test procedures described in this test method can be used to determine the percentage of gaseous products, exclusive of moisture vapor, of any particulate wood fuel meeting the requirements specified in this test method.
SCOPE
1.1 This test method determines the percentage of gaseous products, exclusive of moisture vapor, in the analysis sample of particulate wood fuel that is released under the specific conditions of the test. The particulate wood fuel may be sanderdust, sawdust, pellets, green tree chips, hogged fuel, or other type particulate wood fuel having a maximum particle volume of 16.39 cm3 (1 in.3). Volatile matter, when determined as herein described, may be used to indicate yields on processes to provide the basis for purchasing and selling or to establish burning characteristics.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.
