ASTM D2017-05

Standard Test Method of Accelerated Laboratory Test of Natural Decay Resistance of Woods (Withdrawn 2014)

SIGNIFICANCE AND USE
This test method is useful in determining the relative decay resistance between various species of wood. It is an initial means of estimating the ability of a wood species to resist severe microbial attack and, thereby, qualifying the performance level of a wood species.
This test method is not intended to provide quantifiably reproducible values. It is a qualitative test method designed to provide a reproducible means of establishing relative decay resistance between various species of wood.
SCOPE
1.1 This test method covers the evaluation of the natural decay resistance of wood. The test method may also be used to evaluate the resistance of wood products or of other organic materials subject to decay by wood-destroying fungi, such as those employed in the test.
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.
WITHDRAWN RATIONALE
This test method covers the evaluation of the natural decay resistance of wood. The test method may also be used to evaluate the resistance of wood products or of other organic materials subject to decay by wood-destroying fungi, such as those employed in the test.
Formerly under the jurisdiction of Committee D07 on Wood, this test method was withdrawn in May 2014. This standard is being withdrawn without replacement due to its limited use by industry.
