ASTM E1690-95
Historical Standard: ASTM E1690-95 Standard Test Method for Determination of Ethanol Extractives in Biomass
SUPERSEDED (see Active link, below)
ASTM E1690
1. Scope
1.1 This test method covers the determination of ethanol soluble extractives, expressed as a percentage of the oven-dried biomass, of hard and soft woods, herbaceous materials (such as switchgrass and sericea), agricultural residues (such as corn stover, wheat straw, and bagasse), and wastepaper (such as office waste, boxboard, and newsprint). All results are reported relative to the oven-dried weight of the sample.
Note 1This method may not be suitable for hard and soft wood samples that include bark or those with more than 10% extractable materials.1.2 The values stated in SI units are to be regarded as the 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 and health practices and determine the applicability of regulatory limitations prior to use.
